I now compiled linux-drm-nightly as of today (git 89271faca1 from cgit.freedesktop.org) and the situation has improved a little: when writing to the disk, I get the below output about once a minute, and a pause and (probably) a bus reset, but no more crashes and unusable disks until reboot.

I also tried to use "libata.force=1:1.5G" to artificially slow down the wire speed and this seems to make those errors appear less often, while also slowing down the disk noticeably.
Anything else I should or can try?
Closing. It was a bad disk after all - Linux was right in spitting countless errors at me :-( I have to reopen this bug. Even with 4.0.0-rc7 (freedesktop git checkout as of yesterday), after changing cabling, replacing the disk itself, changing the harddisk position inside the PC case and retrying all of the above again, I still get these timeout errors with all consequences (filesystem being corrupt, remounted read-only, etc) when copying large amounts of data.
The new disk is - according to SMART - perfectly OK and works as long as I do not copy large amounts of data (roughly for up to 30 minutes). In the syslog output, I can detect no references to hardware errors - only timeouts. This might be due to the "shingled tracks" of this disk, which require rewriting adjacent tracks after write processes, which might cause the timeouts on the OS side (but that's just a guess).
Anything else I can try? Is there a way to increase the DMA timeout values so the OS waits longer?

Update: error also occurs when increasing timeout in /sys/block/sda/device/timeout to 120 (seconds). Will try 240s next. (But is this a solution?)

But Linux doesn't think so and eventually times out. According to this article http://www.storagereview.com/seagate_archive_hdd_review_8tb, the disk seems to work as designed - and the OS should be able to cope with long(er) timeouts because the disk needs time to perform an internal garbage collection after large writes, similar to TRIM on SSDs. However, in their tests the write performance was bad but writes never completely stopped so there were no timeouts (as far as I can see) like in my case. I need to decide within the next week whether I keep this disk or exchange it for a smaller non-shingled disk at a slightly higher price (e.g. WD Green 6TB): is this a pure Linux issue, should I keep the disk and wait for Linux to support it, or are chances that I got another bad disk and I should give up on Seagate (again)? Please reply. Thank you! See also http://serverfault.com/questions/682061. I have the same failure with the same drive and newer kernels. But kernel 3.16.0-4-amd (Debian build) and 3.18.10 had uptimes of 19 and 26 days respectly. I have tried all new kernels since, but they crash my system (including 4.0.1). I'm experiencing similar problems with three different Seagate Archive 8TB drives. I used 3.18 patched with multipath-tcp to fill the drives with existing data and switched to 4.0.7 afterwards to make use of overlayfs merged in 3.19. After this change, I was unable to successfully write larger amounts of data (>10GiB) to the disk without having severe problems like others mentioned before. I support the idea that the drive is doing some kind of internal garbage collection between writes and seems unaccessible during that time. This can even be observed by running the drives with 4.0 until the error occurs and then rebooting to 3.18. The drive will still be unaccessible after rebooting and spit out ATA errors. Even my UEFI doesn't show the drive identifier at that point. After powering down the system for a few seconds, the drive seems to continue to work just fine. Thanks for filing this bug, I was unable to connect the dots myself and would have never guessed that this is actually caused by the kernel. I started to replace hardware and was going crazy about this problem. I'm recreating my SnapRAID parity drive at the moment and the parity drive has written over 2TiB without a single error in dmesg on 3.18.6. I also raised this issue with someone at Seagate, I hope they're interested in this too. Thank you! Just to echo a "me too". I've had the same expierence on 4.0.7 and 4.0.6. 3.14 works without issue. I have some more notes here. https://bbs.archlinux.org/viewtopic.php?pid=1542409#p1542409 Just another data point: I have exactly the same issue as OP with 4.0.4 and 4.0.8 kernels. As many ppl are reporting: 3.14/3.16/3.18=OK; 3.19/4.x=NOK I definitely think this is kernel regression in kernel support(tollerance) for SMR DM drives. Following patch (0006-revert-Implement-ATA_DEV_ZAC.patch) on 4.0.8 allows me to successful write 7T of test data without any SATA error. Without patch drive interface goes down after 50-150G of writes.

Workaround patch for kernel 4.0+
Hi, Thanks for finding this solution. I have two questions: 1. I guess this patch is not the final solution, because it is removing previously added functionality that, to my understanding, was supposed to help for handling SMR drives. Wouldn't this be needed sooner or later? Is this issue further investigated? 2. I have checked all releases up to kernel v4.2 rc7. The problematic code is still in everywhere after v3.18. Does anybody have information when this issue would be fixed for good in the mainline Kernel? Best regards, Jörg Got this problem with 2 different Samsung 8Tb SMR drives. The issue is very annoying. Any chance to see it fixed? Created attachment 186701 [details]
Bisect to locate error for Seagate ST8000AS0002 archive drive
description: Motherboard
product: M4A88TD-M EVO
Model Family: Seagate Archive HDD
Device Model: ST8000AS0002-1NA17Z
Firmware Version: AR13
Bisect log attached.
The last working (good) version I'm sure has the commits that have previously been recommended to be reverted.
With some failures, drive is accessible and responds to smartctl other times it's not. Upon failure the machine must be switched off to get access to the drive. Even then the drive can sometimes report a smart error in bios. It will then restore itself.
Using the patch at http://marc.info/?l=linux-scsi&m=144062955906401&w=2 git checkout v3.19 git apply <patch> compiled but didn't fix the problem. git checkout v3.19 git revert f9ca5ab832e7ac5bc2b6fe0e82ad46d536f436f9 9162c6579bf90b3f5ddb7e3a6c6fa946c1b4cbeb compiled but didn't fix the problem. The smart end-to-end error attribute has started to climb on the drive so will switch back to 3.18 to eliminate hardware error. sweeneygj@, if you have a chance, could you please bisect this issue between v3.18 and v3.19 tags?

Sorry about the delay. Just got back from vacation. I'm a bit confused as to why 4f258a46346c would be the culprit as it should only affect sizing of BLOCK_PC requests which none of these are presumably are (I see WRITE FPDMA QUEUED in the log above which would be a REQ_TYPE_FS). The only way my patch would change the behavior for FS requests would be if somehow the ata host did not set max_hw_sectors and is using the new, larger default introduced by Christoph's patch. But I don't see anything obvious in libata that would suggest max_hw_sectors is not getting set. Anyway. I'll look at it in detail tomorrow. Worth noting, I tried these drives with NCQ disabled, and they still behaved the same way. I can't test anymore as I'm using the drive. I'm running with an old kernel for now (3.14) What about kernel 3.19? Is there anything I can do to fix/workaround this issue? I have installed Ubuntu server 15.04 on x86-64 platform. Any news? Hi Futuref, I am also running Ubuntu and have the same problems. There are also older Kernels for Ubuntu 15.04 (Vivid). See: http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=M;O=D I did downgrade Ubuntu 15.04 to 3.18.x kernels and that works well for me. The problem seems to start with the 3.19 Kernels and I do not have any problems with the Seagate Archive drives and the 3.18 Kernel. I also did not find a good work-around for the 3.19 and newer kernels. For the time being this works well for me and I plan to stay at this kernel version until the problem is solved and the solution made it into the Ubuntu mainline kernel. Hello joergn, I was excatly looking for such concrete instructions :) Doing the downgrade to 3.18.x made it work again. The drive just goes and goes... Thank you so much! Here's another data point. I'd been experiencing the same issues (albeit with BTRFS). Now running kernel 4.3rc5-1 and all is well again.

I'd love to but both my SMR drives are part of my BTRFS pool so I can't direct a write to a single drive :-( If you have BTRFS then 'balance' operation is an easy way to trigger this error. With 4.1 kernel 'btrfs balance' fails after 10 minutes for me. Haven't tried recent kernel.

OK great, will be starting a balance today - will report back Unfortunately, I also see these errors with 3.18.22 (-31822-lowlatency) on Ubuntu 15.04 with a Seagate 8 TB drive. I will try if 3.18.21 works as others said this version was working for them. Hi Mario and others, I am on Ubuntu 15.04 and Kernel 3.18.22 since ubuntu made that version available on their server. I have 3 of the 8TB drives and they were stable with all the 3.18 Kernels I tried. I must however say that I did not do a serious stress test but use them by pushing larger media files to the drives. Maybe I am just lucky. Any later Kernel I tried did cause massive problems with my usage profile. What did you do in order to see the error? Has anybody tried Ubuntu 15.10 with its 4.2 Kernel yet? I am a little bit hesitant to upgrade because of the potential problems. I'm not 100% sure it is the same fault but my headless machine died again today with 3.18.21-generic while doing a BTRFS send/receive to the 8 TB drive. After a reboot, df says it stopped at 275 GB of ~5TB total amount of data to be transferred. The machine had no other duties. Before the send/receive, a ~14h long SMART self-test completed and it has found no errors. A related response from a Seagate engineer... in April :( http://marc.info/?l=linux-ide&m=142956580918560&w=2 I will try if it works if I suspend the send/receive from time to time so the drive can flush its buffers. Why not getting in contact with Seagate directly? Are there any devs who could talk to Seagate kernel spezialists? I have written an email to adrian.palmer@seagate.com, but did not get a response yet. I guess it would help to build up a sustainable solution. Created attachment 191421 [details]
dmesg of the session where I'm experiencing problems on 3.14, ncq disabled
I just replaced one of my 8TB Archive HDDs because it was faulty, the drive wouldn't even start properly in the end. I assume this was unrelated to the problem here.
Now that I've gotten the replacement, I've added partitions, encrypted the partition with dm-crypt and created an ext4 filesystem on top of that.
Then I started recovering my data via SnapRaid, after around 200GiB the sata errors started to come back up. I attached the complete dmesg for reference.
I'm using kernel 3.14.51 with NCQ disabled.
I've talked to Adrian Palmer in the past, I also tried to make him aware of the problems we're having here. I really hope I can get this drive to work sometime soon without having to constantly worry about problems...

Yesterday, the drive went even further. After doing full power cycle, the drive didn't come back up (COMRESET failed before opening my encrypted /, not showing up in lsblk). Even I physically moved it into another machine, the drive didn't show up in Linux and even Windows 7. However, I noticed a periodic, even rhythmic noise from the device so I guessed it was 'doing' something, so I let it sit for at least 20min, then the noise had stopped. I rebooted the machine and the drive was visible in both Linux and Windows. I then moved the drive back to the original machine where I started the SnapRAID restoration procedure. Because I restored around 370G so far, SnapRAID verified this first so it read around 370G, which worked flawlessly until around 360G, then I got input/output errors and SnapRAID stopped. The attachment contains a log of this session plus a smartctl -a. I'm now running a full test with 'SeaTools' (on Windows, the FreeDOS based ones are plain buggy), I _think_ this drive is faulty. Sorry for the noise here, I hope this can be figured out....

So far all the information I could find regarding that combination was that it is not advised by Seagate, due to the SMR performance characteristics. By using BTRFS, which only writes actual data during rebuilds, I hoped to mitigate that "problem". > git checkout v4.3-rc7 > git revert 4f258a46346c > git apply <patch linked to in comment #17> Has been running for over a week now with different I/O patterns and without problems. > It would be better to test on a single drive: can you safely btrfs delete > device? Unfortunately no. I'm currently running a degraded RAID1 with one disk only, which hopefully amounts to something like a single individual disk ;) Figured out what's going on. Patch coming...

Applied to 4.3 and 240GB transferred without error. hmm I also have some of these drives (ST8000AS0002-1NA17Z Firmware Version: AR13) and interestingly I've never had these problems... I always ran at Debian sid (which is right now kernel 4.2.6) but I guess I got one of the first drives that were sold in Germany (when did they come out?) so I must have started with an older version. Also, I use btrfs on those drives and once send/received one nearly full fs (6TB or so) in one bunch to another 8TB disk... and I noticed no single error[0] So either the difference is btrfs, or something in Debian... or perhaps that I'm always running these devices via a USB/SATA bridge (with USB3.0 though)... so perhaps I never ran into these issues because of the slowness of the bridge. HTH [0] Well I have other problems now, but I guess these are purely btrfs related: http://thread.gmane.org/gmane.comp.file-systems.btrfs/50107 Hi, just wanted to chime in, in case this helps things further along. I'm experiencing the same problems as everyone else here. I'm running Debian Jessie (current stable), with a own compiled kernel 4.3.0 and using BTRFS as a filesystem. I have a server with 4 drive hotswappable drive bay. I bought a 8TB Seagate HD, stuck it in the bay, and proceeded to copy data to it. After about 40GB, the drive stopped responding and I noticed a lot of kernel errors. I figured the drive was faulty, so I ordered a replacement from amazon. So the replacement arrived. I figured, this time I'd test it out first before I integrate it into my storage array. I hooked up the drive to usb-sata adapter, formatted with btrfs and proceeded to rsync my data onto it. This ran the whole night and I managed to copy 670GB of data onto it. Via USB2.0 the data rate topped at about 20MB/s. I figured the drive is good, so I put into the drive bay of my server. Now directly attached via SATA. And lo and behold, dmesg errors again. Just like everyone else has been reporting. I'm not sure if it's simply the lower transfer speed, or the things are differently managed via a USB interface. By the way, when the drive was attached via USB, I had it connected to a different computer running Debian Jessie with the 4.2.0 kernel. I've now downgraded my server to kernel 3.16 to see if the errors still persist. Just a Comment from my side. This is definitely not just BTRFS related as I am having the same issues using EXT4 on 4.1 kernel (Ubuntu)... I'd say the circumstances that provoke this issue are clear now. We should all test the patch of Martin in Comment 67 now with kernel 4.3 in order to get this patch into the next kernel version asap. I'll start a send/receive of ~6TB during the weekend. Martin, It is possible to prepare patch https://bugzilla.kernel.org/show_bug.cgi?id=93581#c67 for 4.1 mainline? I have 24/7 server running 4.1.8 with Seagate 8T SMR and all problems listed in this bugreport. I can easily test how Your fix is working in 4.1 kernel. (In reply to Robert Krig from comment #71) > > I've now downgraded my server to kernel 3.16 to see if the errors still > persist. Just wanted to mention, rsync has been running for a few hours now. Copied a further 900GB of Data. No kernel error messages what so ever on the standard Debian Jessie kernel "3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt11-1+deb8u5" Martin K. Petersen, I was running Arch with 4.3 kernel + your patch and it makes the error go away. I was running 'btrfs balance' for more than 24 hours now with spikes of additional read/write traffic. Arch 4.3 kernel with your patch handles it. No any kernel messages/errors. Everything looks good now. Thanks Martin for the patch. When it is accepted upstream please 'CC' stable kernel also. It would be great to see it in 4.3 as well. Hello together, as this ticket was created on the branch 4.19.x, I was wondering if this branch might get patched too, Ubuntu is running on it... Ubuntu 15.10 (Wily) v4.3-0-g6a13feb with 7c4fbd5 from Comment 67 Ubuntu scripts from http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.3-unstable/ Model Number: ST8000AS0002-1NA17Z Firmware Revision: AR13 I'm filling a new btrfs with ~6T. This seems to be working. I'm only on 160G, but it failed long before this with the the generic amd64 Ubuntu 14.04.3 LTS and 15.10 kernels. I will report if "WRITE FPDMA QUEUED" returns. Thank you very much, Martin K. Petersen! Is there anywhere else I should post in support of the patch? It looked like a very small conflict to apply it to Ubuntu-4.2.0-19.23-0-g22ed8ce, but for me it was easier to just build v4.3. (In reply to Martin K. Petersen from comment #67) > Please try this: > > http://git.kernel.org/cgit/linux/kernel/git/mkp/linux.git/commit/?h=bugzilla- > 93581&id=7c4fbd50bfece00abf529bc96ac989dd2bb83ca4 Thanks Martin for supplying the patch, I applied it to kernel 4.3.0 and booted a J1900N-D3V board with the ST8000AS0002-1NA17Z FW AR13 with it, SATA2 3Gbps. Created a 2.3T partition (after a first 5T one), btrfs single d/m/s profile and started filling it by rsyncing data over Gbit LAN. 1.5TB transferred with roughly 50MB/s transferspeed total average, no ATA errors in dmesg. Then I put the drive in an H87M-PRO board, SATA3 6Gbps. Same transfertest, also no ATA errors in dmesg. The 5T partition is bcache + dm-crypt + btrfs(compress-force=zlib,nossd) that I have filled with kernel 3.18.22 on an AMD E-350 board, also without ATA errors in dmesg (total average roughly 10MB/s). Then doing 3x parallel dd_rescue /dev/sdX file (3 independent SATA devices, files on 5T) resulted in ATA errors soon after transfers started. After about 150GB in total, the 5T fs went ro and kernel BUG in btrfs/extent-tree.c due to the I/O errors I assume. My machine successfully transferred a 5 TB btrfs subvolume with kernel 4.3 and Martin's patch. I will compare the data now but everything looks good so far. Thank you Martin! Hi, will this bug ever officially been fixed? How can i fix this bug without changing the kernel, now i cant use my virtualbox, because of an missing 'modprobe vboxdrv' .. Without the fix my hdd is clicking all the time and is slow and same times unaccessible. With w7 it worked fine. How can i add the fix to the existing kernel? Hi, kernel 4.4 was just released. I checked the changelogs but I didn't see any mention of this bugfix. Does anyone know if the patch that fixes this bug has already been implemented in upstream kernel 4.4 release? Good news, Martin's patch was accepted: Your commit has been added to the upstream scsi tree On branch "fixes" This patch is scheduled to be pushed for 4.4 Great news!!! And this patch should be absolutely backported to stable kernel as well. This patch is part of upstream kernel now. Its upstream sha is ca369d51b3e1649be4a72addd6d6a168cfb3f537 Thanks for your work Martin. Could you please send it to stable maillist please? The change should be really backported to previous kernel versions. I am running a btrfs balance on 4.4rc4 (which has the patch) and can confirm it seems to be working. No errors so far, and the balance is almost done. I have upgraded the kernel from 4.3.0+patch to 4.4.0-rc4. /sys/block/sdb/device/queue_depth is 31, 3Gbps SATA (chipset limit), the disk is an iSCSI target and roughly 400G extra has been written/pushed to it so far. No errors, all runs fine. I compiled 4.4.0-rc5 and gave it a try. I am not facing any ATA errors like before but now drive is sooo slow (and also quite warm). For writing data (I do copy with Midnight Commander) it shows almost 1MB/s. I don't know are my problems now related to luks or something else. I am running ext4 inside luks container.

Is that drive almost full? SMR drives will slow down a lot when they start to fill. No, I have managed to copy less than 1gb. It's sooo slow. I dont think SMR disk speed would ever reduce to these speeds. (In reply to shan from comment #90) > No, I have managed to copy less than 1gb. It's sooo slow. > I dont think SMR disk speed would ever reduce to these speeds. btrfs rebalance was doing ~55MB/sec for a few days straight to ours. That was with -rc4, and about 70% full. The "blocked for more than 120 seconds" messages are I suspect just telling you what you already know—it's going slow. Suggest checking smartctl, iostat, etc. I did many tests, removed luks, tried with plain ext4, attached straight to sata (I used it from the usb docking station). Funny thing was that from usb docking station it copied 800Mb fast (at least Midnight commander showed show), before it froze. Attached to sata it copied 1600Mb fast before frozage. Then I started to play with partition table and noticed that parted and fdisk made partitions which always gave warning about alignment? "Warning: The resulting partition is not properly aligned for best performance.". Then I created partition with gparted and now parted showed: (parted) align-check opt 1 1 aligned And voila now I have managed to achieve those ~55MB/sec speeds. Hmm sounds quite worrying... while it's understandable that you may suffer from some performance penalty when you fs (or any other block layer) isn't aligned, one shouldn't suffer from freeze... :( May indicate that the fix isn't complete yet. I have now copied 6TB of data and everything seems to work. But, I have got two of those "Blocked for more than 120" messages and I thought that disk will freeze again, but with both cases it continued with good speed. This happened when I had copied around 70GB. There was something about ext4 lazy init, If I remember correctly (I lost logs), also there were some messages related the source I copied data from (seeks errors with USB drive). It could be that errors with source made these "blocked" messages. Found the logs for those two "blocked for more than 120". I think these are not related to the source, the source errors happened later. Dec 25 09:17:22 i7 kernel: [ 1560.020132] INFO: task ext4lazyinit:2009 blocked for more than 120 seconds.

The system being unresponsive for a while, but then continuing without any errors except e.g. those 120s blocked messages? Cause that could be just "normal" (or a pointer that the IO scheduler could be improved ;)... but if "freeze" means the system crashed or became unresponsive forever, that would be a "real" bug. Those "blocked for more than 120" are probably no reason to worry much. Did you experience any other fs corruptions then? Before first bugfix, yes I lost everything (I am using luks). After fix I haven't faced any corruption (At least luks container is still intact). Hmm problem is that I dont know how Midnight Commander works, but that is my "frontend" where I see this frozage. Frontend shows me progress of copying process. It shows nice bar where first 800Mb goes really fast to the disk before it freezes, it is normal behaviour (at some point) because it waits for data to be really written to the disk (sync). During progress it calculates the average speed. After this 800Mb Midnight commander is unresponsive and average speed goes as low as some kilobits/s. I can try to stop copying process or shutdown the computer but it takes many minutes (Even tens of) until something is responded from midnight commander. So, continuing without errors... Yes but with that ~2KB/s speed. There seems to be 10 of those blocked for messages and after that no errors on logs, but this frozage continues until I managed to restart computer and stop that copying process. This was before I recreated partition table. Currently after my partition table fix I think it is "normal operation" because after both of those "blocked for" messages copying continued with reasonable speeds ~70MB/s. And I didn't face em anymore (7TB copied now) seems to be much slower at the end, but if I have understood correctly it's the feature of this disk. Unfortunately, using the latest kernel doesn't work for me.

I made some tests with different hardware configuration so if you experience some issue too, perhaps this (very long) comment can help you to find a solution to be able to use your hardware.
I bought some of these drives to backup personal data (two 4Tb RAID1). My idea was to regularly backup both RAID arrays on one drive, while older copies are kept on others drives in lockers in some different geographical locations, then regularly swap the drive who receives frequent updates with one of the drives kept in different geographical places.
Like other people in this thread, I want to use the ext4 file system on a LUKS volume. Perhaps it can fool the hard drive internal garbage collection other people talked about if this use case prevents linear writing.
Since I own a e-SATA/USB 3.0 dock, I was innocently planning to use it to sync my data on the frequent backup drive. I've read some people in this thread tried to use these drives this way too.
It's a very bad idea to use a dock with this kind of hard drives and does not work at all. I tried 3.18.0, 3.18.21, 4.3.3 and 4.4.0-rc7 kernels with my hard drive dock without success.
This is my test:
1. plug
2. cryptsetup luksFormat
3. cryptsetup luksOpen
4. mkfs.ext4
5. mount
6. umount
7. cryptsetup luksClose
8. unplug
In two cases (detailed below), I tried to write some files between steps 5. and 6.
For information, that is what the kernel printed in dmesg about my dock when used in USB 3.0 mode:
[ 4336.726082] usb 4-1: new SuperSpeed USB device number 2 using xhci_hcd

I've not used any USB 3.1 / UAS dock so I can't tell if it works.
When I plug the hard drive I get:

Some time it also printed:

Increasing the '/sys/block/sdk/device/timeout' value only hide "task blocked for more than N seconds" messages but does not prevent "I/O error" messages to print.
The mkfs.ext4 took 12 minutes to finish. During this time, the hard drive was not available (I was not able to query SMART data for example).
I don't know if that I/O error message means my file system is broken or not.
After the mkfs was complete, I tried to mount the file system, it took 6 minutes. Then I tried to unmount the file system immediately without writing something, it took 35 minutes to unmount.
I've tried that with 3.18.0, 3.18.21, 4.3.3 and 4.4.0-rc7 kernels without success. I got the exact same behavior each time.
During all my tests, these are the process that triggered a "task blocked for more than 120 seconds':
- ext4lazyinit
- jbd2/dm-7-8
- mkfs.ext4
- mount
- pool
- smartctl
One time I tried to write some data on the hard drive (using rsync), it took more than one hour to write around 300Mb.
Then I tried to use my hard drive with the same dock in e-SATA mode (with a 4.3.3 kernel).
The kernel printed that in dmesg on hotplug, formating with LUKS, doing some smart queries, and creating a file system:

The hard drive went completely wrong during the mkfs.ext4 step and that step was not able to finish, I had to force the hard-drive / dock shutdown leaving the hard drive with an incomplete ext4 file system on an opened LUKS volume (very bad).
Then I tried to use the hard drive on an internal SATA III plug. It's not convenient since I want to be able to hotplug it only at backup time, and these strange hard drives seem to not have standard screw hole on the underside (I can only screw on 2 screws instead of 4 on my bays like my other 4Tb Seagate hard drives). But I need to know if these drives works on internal SATA, because if not I bought expensive paperweight instead of hard drives !
I tried it on a 3.18.0 kernel only (my test is not finished), but it works.
The mkfs.ext4 took only seconds. Then I started to rsync my whole file tree (two file systems on two 4Tb RAID1 volumes). It started fastly then around first 100Gb it slowed down. Since that it's continuing without error. It's slow but it works. It took 2Tb of data in 12 hours, so it will take some days to complete the test. It's not a problem to me if it's so slow since next rsync will only update modified files (it will be far far faster next time to only write differences).
The kernel printed some 'task blocked for more than 120 seconds' but I never got any 'I/O error'.
So, it seems to works only when I use an internal SATA III connection. If someone wants to use one of these drive, an external dock is not yet an option. If something can be optimized in the kernel to improve the hard drive management, some improvement must be done in e-SATA and USB code too to be able to use theses drives in external docks. If you plan to use an external dock and can't plug your drive internally (using an hotswap bay if you need hotswap), do not buy these drives, you will lose your money.
Since I need to hotplug my drives easily, I bought a SATA III hotplug tray-less bay that fit in a 5.25" CD enclosure. I've not received it yet but I did not expect any issue and it's probably the only current solution for people wanting to hotplug/hotunplug these drives. I strongly recommend to buy one bay with an integrated fan since I noticed that these drives can heat a lot !
I found two interesting trayless hard drive hotplug bay to put in a CD enclosure :
* Icy Dock TurboSwap MB171SP-B
[ http://www.icydock.com/goods.php?id=169 ]
+ trayless
+ can get 3.5" hard drives (and 2.5" drives if you need that one day)
+ integrated 80mm fan (probably not very noisy, and you can replace it with a bigger one if you have the space)
+ variable fan speed (front button)
+ poweron/off front button
- underside fan (you need to keep space below, it probably does not work correctly if you stack multiple of them).
* StarTech HSB110SATBK
[ http://www.startech.com/HDD/Mobile-Racks/525in-Trayless-Hot-Swap-Mobile-Rack-for-35in-SATA-HDD-with-LCD-and-Fan~HSB110SATBK ]
+ trayless
+ can get 3.5" hard drives
+ integrated 40mm bottom fan
+ you can stack multiple one (bottom fan)
+ screen displaying hard drive temperature and fan speed
+ can adapt automatically fan speed according to hard drive temperature (plus some button to manage that) and buzz some alarm in case of big problem
- the fan is probably very noisy (very small, like the one you find in rackable servers)
- this bay costs twice the price (compared to the other one)
I've bought the first one and I will receive it soon. If you have bought some of these 8Tb Archive hard drives and want to be able to hotplug them, it's probably the only solution available to you currently. I chose the first one since I only need to power it at backup time, and I can just put the fan to max speed during this time, and monitoring hard drive temperature using SMART. If I got some issues I will tell you.
I hope the kernel will receive updates soon to speed-up the writing, but with that kind of bay, you can already hotplug your hard drive today. You'll probably have to wait more more longer to be able to use them on some USB 3/e-SATA docks which is not an option at all today.
After the end of my current test (in some days), I will try to reproduce it on a blank disk using a newer kernel.
Sounds just like my case. I managed to get my drive to somehow working state after creating proper partition table. Fdisk and parted made partitions which always gave warning about alignment? "Warning: The resulting partition is not properly aligned for best performance.", and always performance was terrible, and that unmounting took ages. After I created partition table with gparted, alignment was ok and drive worked quite well, (parted) align-check opt 1 1 aligned You can check the above command with qparted and see is it aligned. I created my partition with alignment in mind :) root@box:~# cat /sys/block/sdk/queue/physical_block_size 4096 root@box:~# cat /sys/block/sdk/queue/optimal_io_size 0 root@box:~# cat /sys/block/sdk/queue/minimum_io_size 4096 root@box:~# cat /sys/block/sdk/alignment_offset 0 root@box:~# parted /dev/sdk GNU Parted 3.2 Using /dev/sdk Welcome to GNU Parted!

I hope it's OK since the Startech one is an older product that was designed years before 8Tb drives exist (and on his side, Icybox officially claims 8Tb drive support), and since I already found incompatible stuff with these 8Tb Seagate drives (screw holes incompatible with my computer case internal trays), I'm a bit apprehensive. On his side, the drive already wrote 3Tb without any errors, with a rough average 50MB/s writing rate, which is the rate Henk Slager had with a 4.3 kernel patched with Martin K. Petersen changes. On my side I'm still running a 3.18 kernel, I will try a 4.4-rc7 one soon. (More senior members, correct me if I'm wrong with the following) But guys,... this bug isn't about block layer alignment optimisations, is it? If one doesn't align the blocks properly, one likely gets some warnings and bad performance. There are many resources out there how to do it right... and most current tools will do everything right out of the box (by auto-detection) or simply fall back to some smart alignment values (e.g. 2048S) which also work out-of-the box for most cases. What this bug, AFAIU, is about: actual data corruptions, block errors, that happen on these SMR devices (typically the 8TB one from Seagate). So if you still see block errors / corruptions like the original posters did - even though you have the patch in place - just post. If you see other corruption errors or completely unexpected performance issues, which may be related to SMR... open a new issue, reference it here. But we probably don't need message from everyone who ever sees the typical "process blocked for 120s" message. Best, :-) Well, my comment shows one use case with I/O errors while creating a file-system on the drive and one use case where the drive go wrong for real, needing an hardware shutdown of the drive while the file-system is mounted.
I wrote my comment because I read some messages above about people playing with these drives with external (i.e. not internal SATA) link, and I think it was useful to assess the situation. The same way we probably don't need "process blocked for 120s" messages by everyone, we probably don't need reports on non-SATA use cases. My intent was to point the fact that until theses drives work correctly on SATA link, it's pointless to try to get them working with other links through various interface. It seems clear that the fixes to get them working over SATA are not sufficient to get them working over something else, so if someone wants to try some new kernel or patch, he must know his test is only valid over SATA cable, otherwise he can mark out as faulty a patch that works.
Also, I added (and yes it was free and it fixes nothing upstream) a comment to help other people who can't use their drives today for the usage they bought them for (currently, since I can't use my drives for what I've bought them for, my drives are just expensive paperweights). While waiting for fixes being mainlined, it's good to share functional workarounds. It looks like some people have expensive paperweights since 10 months.
So to quote yourself:

Yes, using an USB/SATA bridge adds some other issues that can hide fixes, it's good to know this use case it's not a valid test (proving that is the main purpose of my comment, which is precious).
Hi, Here I have one 8 TB in SATA and another one that's the external version, which is UAS USB3.0. My use case is backup and archival (rsync, attic/borg backup, snapraid). Filesystem is btrfs, and we also have an AES-encrypted DM in the mix. The one thing I can tell for now, is that running 4.4.0-rc8 I still get errors such as: UAS: [ 4554.977414] sd 18:0:0:0: [sdt] tag#18 data cmplt err -71 uas-tag 20 inflight: CMD [ 4554.978207] sd 18:0:0:0: [sdt] tag#18 CDB: Write(10) 2a 00 50 28 d3 c5 00 00 80 00 [ 4554.982406] xhci_hcd 0000:00:14.0: ERROR Transfer event for disabled endpoint or incorrect stream ring [ 4554.983193] xhci_hcd 0000:00:14.0: @00000000d89916f0 00000000 00000000 04000000 0b048001 SATA, infinite IO to offline device (btrfs issue?): Jan 06 00:16:05 Bidule systemd-journald[28106]: Missed 8 kernel messages Jan 06 00:16:05 Bidule kernel: sd 14:0:0:7: rejecting I/O to offline device Jan 06 00:16:05 Bidule systemd-journald[28106]: Missed 9 kernel messages Jan 06 00:16:05 Bidule kernel: sd 14:0:0:7: rejecting I/O to offline device On top of the usual stuff which has been reported earlier. And I've always been able to perform small transactions (which leads me to think that the mkfs issues could be unrelated); all the trouble I have is whenever I do lots of writes (dozens / hundrds of GB) on the devices. So far I haven't been able to fill one of these in a single shot, except when throttling the write speed to about 20 MB/s, which would give time to the disks to do their garbage collection. @Thomas DEBESSE: As I've said, if people still actually see corruptions I have absoltely nothing against them posting. To the contrary, I'm happy that people actively test and report. I rather meant the the growing number of "it's just slow when alignment doesn't fit reports",... and even to those people I didn't mean it offensive,.. it just easily clutters up this bug more (as my own two messages now as well ^^) and makes it less likely that the actual issues get fixed. :-) (In reply to Thomas DEBESSE from comment #99) > > It's a very bad idea to use a dock with this kind of hard drives and does > not work at all.

Thats correct, I am using this drive quite successfully nowadays in the meaning that I am able to write many gigabytes of data on it (Ubuntu Server 15.10, Kernel 4.2 over SATA). But still I have a bad feeling about some weird "click" and "clack" noises of the drive while active. Might these noises have to do with this bug ticket? Like powerstate is corrupted or prevented? Or other issue in parking the head? The noises are quite loud... I have Upgraded to 4.4.0 running Ubuntu server 15.10 but I am still receiving errors. I copied a couple hundred gigs from one 8tb drive to the other (mirror) and received the errors also with the final 4.4.0 release (Ubuntu mainline kernel)

...I am using ext4 fs...(In reply to alex.wellmann from comment #108) Are you sure your drive is not merely dead? What is the output of `smartctl -l error /dev/sda` and `smartctl -H /dev/sda` (adapt `/dev/sda` with your own drive path)? Here, these drives work well on 4.4.0 kernel from ubuntu mainline when used on direct SATA link (I never seen them working on USB3/e-SATA links). Your drive is probably just dead. I don't know if it can be a problem on the SATA chipset side but it really looks like an hardware fault on the hard drive side. That's also what i thought (hardware failure) but the drives work fine on Windows without any issues and are Connected via SATA directly to the MB (Intel C226 chipset). Smartctl also shows no issues for both drives: smartctl 6.4 2014-10-07 r4002 [x86_64-linux-4.4.0-040400-generic] (local build) Copyright (C) 2002-14, Bruce Allen, Christian Franke, www.smartmontools.org === START OF READ SMART DATA SECTION === SMART Error Log Version: 1 No Errors Logged smartctl 6.4 2014-10-07 r4002 [x86_64-linux-4.4.0-040400-generic] (local build) Copyright (C) 2002-14, Bruce Allen, Christian Franke, www.smartmontools.org === START OF READ SMART DATA SECTION === SMART overall-health self-assessment test result: PASSED I've also replaced all SATA cables before I knew that this probably software related...

dmesg from boot to drive failure after rsyncing ~250 GB of data
> Can you shred the 2nd SMR drive with different sizes (10G/100G/500G/...)?
I ran shred with 10G/100G/500G without any issues. I also checked dmesg for errors but it was clean (no issues). In addition I fired up windows and checked with SeaTools for errors (the end-to-end errors made me nervous) but according to the software all is good. I assume that the end-to-end errors are a result of of issues shown in the logs. I use these drives for some time now - so it is not surprising that errors occurred due to the kernel issues (right?)...
I'm using the 8 TB (AR15) in combination with btrfs on a gentoo 4.3.3 kernel and am experiencing some very strange slowdowns. I have managed to copy 15 TB without trouble and after copy, I like to run rsync -car --progress to verify that the data copied matches the original (bit rot experiences from the past). In this case, it verified maybe 5 TB but looking at the rsync progress I see speeds slowing down after a few hours. The last few files went around 256 kb/s - 2 mb/s. Even slower then what I expect from the garbage collection progress. Additionally, I see kworker going mad: 9012 root 20 0 0,0m 0,0m 0,0m R 99,3 0,0 0,0m 698:42.28 kworker/u8:22 Looking at the btrfs bits, I see they have been active cumulatively but are 'standing still' for this bit: 2658 root 20 0 0,0m 0,0m 0,0m S 0,0 0,0 0,0m 44:35.55 btrfs-transacti I don't know if this is purely a btrfs thing or the SMR causing havoc in the driver stack. From what I understood however, the bad performance of the SMR drives was mostly due to writing to the drivers, with the rsync job really only reading, I'm a little puzzled at to what is going on. dmesg is clean (for reading, when writing i see my LSI controller complaining about delays, but I kind of expected that. After I am able to verify my data is safely copied, I'll give the 4.4 kernel a spin and see if that improves this at all. A slight nuance, I accidentally got my rsync commands wrong and was copying as a subdirectory instead of comparing, so the slow speed may be attributed as to the drive being being written full (about 50gb). The rsync job is running with the proper arguments now and will monitor strange CPU loads. one update: after shredding on the second drive, I have repartioned it and setup a single partition again in EXT4. now i am copying the files from the first drive using rsync and after 4TB of writes strangely still no errors in dmesg... Just tried shreding the drive with 'sudo shred -v -n 1 /dev/sde'.
After ~200 GB shred started reporting errors:

Not tested but: smartctl -t select,445156864-445764455 /dev/sdX should scan the problem area. If it helps... while a proper solution is found, I have had no problems doing 10 TBs of writes using the blkio controller to limit write speed: for x in "8:160" "65:48"; do echo "$x 80000000" | sudo dd of=/sys/fs/cgroup/blkio/blkio.throttle.write_bps_device; done I went gradually up from 30 MB/s to 80 MB/s and then I got tired because it was good enough for me. In my experience, the drives are fine, false positive reports of write failures are not recorded by SMART which would be the case if it was a disk write failure. both smartctl tests finished without any errors: === START OF READ SMART DATA SECTION === SMART Self-test log structure revision number 1 Num Test_Description Status Remaining LifeTime(hours) LBA_of_first_error # 1 Extended offline Completed without error 00% 40 - # 2 Short offline Completed without error 00% 26 - (In reply to Bartłomiej Romański from comment #130) > both smartctl tests finished without any errors: So the drive is OK. If there is a bug, running shred again should trigger it. However, see comment #108 and comment #120. Same kernel and hardware, two different results. If the bug from comment #115 appears again, you may need to go back to 3.18.X and see if rsync triggers the error. Finally, I've just shred an old 750GB drive and got I/O errors. No smart errors. so shred errors can be ignored. The drive seems to be working fine now. I've followed the protip I've got in private: - turn off the PC - disconnect power cable from the drive - wait a few minutes (to be super sure!) - reconnect the drive and start the system After this "very hard reboot" the drive is magically working fine. I've mananged to shred the whole 8TB and rsync ~1.5T without any errors. Thank you for all your help. I'm running 4.4 since release and it seems to run without problems now, big thanks especially to Martin. However, 4.3 introduced a i915 suspend/hibernate bug that has not been fixed in 4.4 (https://bugs.freedesktop.org/show_bug.cgi?id=92414). Is there any way the SMR patch in question can be backported to 4.1 lts? IMHO, a patch like this even qualifies for inclusion in an lts release such as 4.1. Created attachment 203711 [details]
Log of drives interfering with other disks on same controller
Hey,
That patch works like a charm some of the time. But if I have disks on the same controller it seems to cause a cascading failure of all disks on that controller.
So the configuration of that 4 channel SATA controller is:
/dev/sdi /dev/sdj are in a btrfs raid1 both seagates 8TB disks
/dev/sdg /dev/sdh are in a md raid1 both western digital 1TB disks
# uname -a
Linux marvin 4.4.0-rc8-amd64 #1 SMP Debian 4.4~rc8-1~exp1 (2016-01-04) x86_64 GNU/Linux
If I copy data to the btrfs at some point in the future everything will fail disabling all devices on the controller. I have tried to increase the SATA timeouts and have also tried throttling the data using blkio but that just delays the failure. I'm trying to copy from a raid5 in the same host to the seagates 8TB drives. If I do it without any throttling it will fail within minutes of the rsync actually starting to copy data.
I can confirm this behavior. Having another disk on the same controller makes one of the disks unusable. In my case, I can't even mount the file system. Disconnecting one disk resolves the issue. |
Created attachment 167811 [details] HDD info (hdparm -I) I have a brand new Seagate 8TB archive disk: Model=ST8000AS0002-1NA17Z, FwRev=AR13, SerialNo=..... I formatted this with LUKS + ext4 to use as an archive disk under Ubuntu 14.04 with an updated mainline kernel (3.19.0-031900-generic #201502091451). I use this instead of the stock Ubuntu kernel due to buggy Haswell PM support in everything < 3.17. The mainboard is a MSI B85M-P45 with BIOS 10.5 first, but I also upgraded to 10.8 and tried again, no help. hdparm and smartmontools all report no errors with the device. I also tested multiple SATA cables and power cables, which work fine with other SATA devices (one SSD and one WD HDD). When I copy data onto this disk (using rsync or the Ubuntu desktop), after some time (~200MB to ~5GB) the copy process stops and I see this in dmesg: [ 329.994134] ata1.00: exception Emask 0x0 SAct 0x7fffffff SErr 0x0 action 0x6 frozen [ 329.994148] ata1.00: failed command: WRITE FPDMA QUEUED [ 329.994151] ata1.00: cmd 61/40:00:80:ef:db/05:00:01:00:00/40 tag 0 ncq 688128 out [ 329.994151] res 40/00:00:00:00:00/00:00:00:00:00/00 Emask 0x4 (timeout) [ 329.994152] ata1.00: status: { DRDY } [ 329.994154] ata1.00: failed command: WRITE FPDMA QUEUED [ 329.994155] ata1.00: cmd 61/40:08:c0:f4:db/05:00:01:00:00/40 tag 1 ncq 688128 out [ 329.994155] res 40/00:00:00:00:00/00:00:00:00:00/00 Emask 0x4 (timeout) [ 329.994157] ata1.00: status: { DRDY } [ 329.994157] ata1.00: failed command: WRITE FPDMA QUEUED (repeated) [ 329.994254] ata1.00: cmd 61/40:f0:40:ea:db/05:00:01:00:00/40 tag 30 ncq 688128 out [ 329.994254] res 40/00:00:00:00:00/00:00:00:00:00/00 Emask 0x4 (timeout) [ 329.994255] ata1.00: status: { DRDY } [ 329.994257] ata1: hard resetting link [ 335.356764] ata1: link is slow to respond, please be patient (ready=0) [ 340.007083] ata1: COMRESET failed (errno=-16) [ 340.007088] ata1: hard resetting link [ 345.377757] ata1: link is slow to respond, please be patient (ready=0) [ 350.028074] ata1: COMRESET failed (errno=-16) [ 350.028078] ata1: hard resetting link [ 355.394766] ata1: link is slow to respond, please be patient (ready=0) [ 366.312881] sdd: detected capacity change from 31876710400 to 0 After I see this, the disk is usually inaccessible and unusable until I hard reset (power cycle) the system.
