Comment 6 roucaries.bastien+kernel 2011-02-15 09:47:13 UTC
Very hard to reproduce. Take between 30 to 6 hours to get it.

using git pull in parallel increase the chance to hit.

I suffer dataloss at reboot and I rebuild twice my / partition using reiserfsck and restore using a backup once.

Bastien, are you using ACLs or security xattrs (e.g. selinux) on your file system?

If you're not, I'll have to keep looking, but it seems as though Frederic's BKL replacement patches got the nested behavior of the BKL right but not the drop-over-schedule part completely right.

The BKL can do nesting but drops the lock entirely over schedule. The reiserfs write lock can do nesting but only drops one reference to the lock over schedule. So if the lock is nested and a schedule occurs, the lock isn't truly dropped.

The most obvious case of nesting the write lock like this is when using extended attributes since it will nest journal transactions. There are others, though.

I'll work up a patch to test this theory and post it shortly.
Comment 9 roucaries.bastien+kernel 2011-03-28 09:33:30 UTC
Dear Jeff,

Yes I have acl enable.

If your theory is right why lockdep does not detect this kind of scenario ? Do you need a virtual lock in order to lockdep to automatically detect this ?

Sorry for the delay, real life suck

Comment 10 Maximilian Decker 2011-05-02 16:11:07 UTC
hi there,

I'm just curious if there are any news on this ?
I ran into the very same problem (well, at least same symptoms, but nothing specific in the logs) after upgrading openSuSE 11.3 to 11.4 (kernel 2.6.37.1+suse), running rootfs on ext4, dm-crypted /home with reiserfs (rw,relatime) and a non-encrypted reiserfs data volume on top of LVM (rw,noatime,acl).

In my case the system was running for some hours and suddenly after trying to start "kwrite" (I'm running KDE 4 btw.) the /home - Partition was dead, but without dataloss after SysRq-reboot. 
As that specific system is kind of support and development system for me, I immediately reverted back to kernel 2.6.34 (i.e. openSuSE 11.3 kernel) as a workaround, no freezes since then (several weeks).

I recently also tried to reproduce that issue with Ubuntu and openSuSE on top of a 2.6.38 kernel, using ramdisks and hard disk partitions, but no luck so far, test cases ran for hours without a single glitch.

Well, today I switched my openSuSE (the one that crashed the reiserfs once) to 2.6.38. I have made backups, so let's see what happens. 

I wonder if either hardly anyone suffers from this bug or if it is only caused in some very special combinations, or if it is just gone with 2.6.38.

Reiserfs IMHO has been a rock solid, fast and reliable file system over the last years, and I would hate to be forced to drop it just because of that silly weird bug .... :-/


cheers,

- Maximilian
Comment 11 Frederic Weisbecker 2011-05-11 14:54:46 UTC
I'm still investigating on this.

I had tested concurrent loops of git-reset/git-merge for 2 days few weeks ago but couldn't reproduce. I think it was on 2.6.38 though.

I've tested the same this night with 2.6.37.1 as in your latest report, but couldn't manage to trigger the issue either.

So now I'm going to test kmail as it seems to often happen as a good trigger for this bug.

I'll give you more news soon.
Comment 12 Frederic Weisbecker 2011-05-13 13:09:03 UTC
Ah I think I finally got something. I've run those git-reset/git-merge parallel loops for one night. No result. I retried with kmail in parallel fetching hundreds thousands emails. Still no result.

Then I let the machine this night doing nothing, there was just kmail in the background.

And today it seems frozen. I can't login, the screen is shutdown and typing on the keyboard doesn't shed it as usual. So I think I finally succeded to get a crash :-D

Now whether it's that reiserfs crash or not, I don't know.

So I'm going to try some more things, this time with a serial console to get the messages.

If you are aware of something more mechanical to reproduce, I'm really interested.

Thanks.
Comment 13 Maximilian Decker 2011-05-17 07:16:24 UTC
well my openSuSE box running on 2.6.38.4 is up for 14 days now, usage is everything between idle and stressed under quite different workloads. 
No crash so far. 

Suspicion arises that somehow the problem is either gone or at least much more harder to reproduce on 2.6.38. It would be interesting why, though.

@Bastien - did you ever get to test on 2.6.38 ?
Comment 14 Maximilian Decker 2011-05-17 09:19:42 UTC
oh no, it just happened again - I should not have commended the 2.6.38.4 kernel for being fine again with reiserfs :-/

The dm-crypted /home reiserfs - Partition is dead again, whereas the other non-encrypted reiserfs partition on top of LVM2 is still accessible. Every process trying to access /home gets stuck now. All the other mounted filesystems (based on ext4, cifs) are ok.

There is nothing unusual in the logs oder dmesg (no debug patches or config options were set in this kernel, however).

The crash happend while trying to save a screenshot, the "save as" dialog opened but did not manage to show the folder contents. At that time the system was quite loaded running several applications and virtual machines (but no out-of-memory condition or whatsoever occured).

So, looks like there still is a serious issue with reiserfs on 2.6.38.
Comment 15 Frederic Weisbecker 2011-05-17 13:15:51 UTC
Ok, good to know.

Well it's fairly possible that 2.6.38 got some patch that lowered the likeliness
of this to happen. In any case I still need to find a way to reproduce that.

I've been unable to trigger the issue again. I'm going to use some stress test tools like xfstools or so and see if that can trigger the thing faster.
Comment 16 roucaries.bastien+kernel 2011-05-21 14:36:59 UTC
I achieved to reproduce on 2.6.37,

Comment 17 roucaries.bastien+kernel 2011-05-21 14:38:28 UTC
Created attachment 58912 [details]
New trace of this bug under kernel 2.6.37 No kmail
Comment 18 Maximilian Decker 2011-05-22 11:06:19 UTC
Bastien,

could you please provide some additional information about your system ?
Maybe it helps finding some appropriate setup for Frederic to reproduce.

Here some specs about my openSuSE that crashed reiserfs twice
(2.6.37.1 after about 6 hours, 2.6.38.4 after about 14 days, now back on 2.6.34)

CPU: Dual-Code AMD running at 800MHz - 3 GHz
GPU: Radeon HD 4200 (shared mem)
RAM: 7 GB
Kernel: Desktop-Kernel (i.e. PREEMPT) 64bits

reiserfs-Partitions:
 /dev/sda7 61GB, dm-crypted, 74% usage, mounted "rw,relatime" (home-partition)
 LVM2-pooled 160G volume (PV /dev/sdb1), ~90% usage, mounted "rw,noatime,acl" (data-partition)

I tried to create some proof-of-concept setup with VMWare and direct mapped old
(i.e. intentionally slow) USB-harddrive (2,5G), using 96MB RAM for the guest OS 
(to force more hdd activity and less cache), using 8 parallel tests and 2 
reiserfs partitions, running on 2.6.37.1 for 2 days without problems.

Another test setup running on native Intel hardware with same kernel and 2 reiserfs partitions on one fast local SATA drive also did not crash within 1,5 days.
Comment 19 roucaries.bastien+kernel 2011-05-23 13:06:36 UTC
Do you mount reiserfs with acl,relatime option ? I believe it is related to acl option.

Comment 22 roucaries.bastien+kernel 2011-05-23 16:35:19 UTC
BTW I use Cached IMAP over kmail. Crash often when mail is synchronized between local and remote
Comment 23 Frederic Weisbecker 2011-05-23 16:38:55 UTC
Ah good to know, I'm setting up OpenSuse 11.4 to get the same system than Maximilian. What distro are you using?

Once it's set, I'll try kmail with that cached imap option.
Comment 24 roucaries.bastien+kernel 2011-05-23 18:54:36 UTC
I use debian testing.

Comment 25 Maximilian Decker 2011-05-23 20:02:55 UTC
Well I did *not* have the acl mount option set for the /home - partition, and it crashed nevertheless. The data partition uses acl, however.
That bug is quite weird.
Comment 26 roucaries.bastien+kernel 2011-06-07 14:23:13 UTC
Any news ?
Comment 27 Maximilian Decker 2011-06-10 12:41:08 UTC
I think we have to wait till Frederic has some way to reproduce the issue ...

I tried to reproduce it myself with different workloads on another machine, 
also created binaries with C doing multiple very fast I/O operations, ran
them for several hours, but it did not crash. (Intel Dualcore ~1,8Ghz).
Somehow it seems to also depend on the system config/specs.

So, to make it short - 
2 crashes on AMD Dualcore 3GHz, 0 crashes on Intel Dualcore 1.8Ghz for me.

@Bastien - what hardware are you running ?

Comment 29 roucaries.bastien+kernel 2011-06-11 17:32:20 UTC
Frederick could you give me some patch for testing ?
Comment 30 Jeff Mahoney 2011-06-13 15:10:47 UTC
I've been running 4 concurrent git clone; rm -rf cycles on a reiserfs file system with a default ACL set and still can't get this to trigger.
Comment 31 Maximilian Decker 2011-06-13 21:37:21 UTC
yes same here I tried to find some sort of testing setup that would allow for 
easy and reliable crash reproduction. No luck so far.

Anyway the machine that crashed twice (running openSuSE 11.4) differs from the
"try-to-reproduce"-machine in at least the following:

CPU running at 3.00 GHz instead of 1.80 GHz
AMD Radeon HD (w/ fglrx binary driver) instead of Intel GPU
had loaded VirtualBox kernel modules
had loaded VMWare kernel modules

That's it. So nothing to really worry about IMHO.
Well ok as far as I can remember the VMWare modules I used actually had some BKL dependencies, the patch for full 2.6.39 compatibility without BKL dep was not yet released that time. But it would be quite far-fetched to blame them.

@Bastien - is there anything notably special about your setup ? 
For now you seem to be the only one being able to reasonably reproduce the issue.
Comment 32 roucaries.bastien+kernel 2011-06-14 09:14:01 UTC
@maximilian: nothing special. Except that it is alway:
- deconnected (aka cached) imap to a 6G google mail account
- something else
Comment 33 roucaries.bastien+kernel 2011-06-14 09:16:04 UTC
@Jeff Mahoney It seems that in 90% of the case a background  deconnected (aka cached) imap to a 6G google mail account is the good way to trigger this bug.

In all cases thanks to try to trigger. Can I test some patch ?

Comment 34 Maximilian Decker 2011-06-20 07:37:45 UTC
I had 4 concurrent I/O tests running for one week now on my AMD machine that 
happened to crash reiserfs twice. The tests did lots of fopen, fclose, fgetc, 
gputc, chmod and stat. No crash. The system was loaded with I/O and CPU usage 
(with the testing processes summing up to nearly 200% (dual-core CPU)).

The filesystem was dm-crypted  and mounted "rw,relatime,acl,user_xattr",
running with the openSuSE 11.4 kernel (2.6.37.1-1.2-desktop SMP 64bits).

Another script randomly set different CPU clockspeeds (for whatever that might
help, but for me the crashes had happend with ondemand CPU scaling governor).

So, to me it seems there must be something else actually triggering the crash. 
Maybe some interfering CPU idling stuff or something like that. Or some very
specific I/O I did not cover with my test. Don't know.

Anyway I could not reproduce with "just" steady CPU and I/O.

Someone else any news on this ?
Comment 35 roucaries.bastien+kernel 2011-08-21 13:00:04 UTC
I can reproduce on 2.6.39. Could not save the trace, but by memory it is the same call trace.

Could you help me and send testing patch ?

I am trying to reproduce with 3.0
Comment 36 Frederic Weisbecker 2011-08-21 14:11:20 UTC
Can you still reproduce under a bound amount of time? Like two days or so?

If so, as I remember you told me your mount options are:
"rw,nosuid,nodev,relatime,user_xattr,acl", can you test without acl for several days, enough to usually reproduce it, and tell us if you can still see the bug? If so it may be nice to retry the same experience with user_xattr.

Thanks.
Comment 37 roucaries.bastien+kernel 2011-08-21 15:18:43 UTC
I could directly answer my / partition mounted with rw,nosuid,nodev,relatime,user_xattr does not crash.

Definivly linked to acl

Comment 40 Maximilian Decker 2012-04-12 11:32:10 UTC
hi all,

I just wonder if there have been any news on this in the meanwhile... ?

As far as I'm concerned the problem did not occur anymore after upgrading to openSuSE 12.1 (running kernel 3.1.x series) about half a year ago. I am still using the same reiserfs (3.6) partitions for crypted /home (no acl) as well as for a non-crypted /data (with acl). 
(in my case it was the non-acl mounted /home that happened to crash sporadically)

Comment 41 Stephan Diestelhorst 2012-06-06 08:32:59 UTC
I do experience the same issue every now and then, with Ubuntu 3.0.0-20 kernel.  Will try to upgrade and see how it behaves.
Comment 42 c880562 2013-02-11 22:17:06 UTC
Hello,

I have the same problem with my linux BackTrack/Ubuntu Full encrypted (/, /home and swap), with kernel 2.6.39.4, 3.2.6 and 3.0.0-23-pae:

I have tried to disable swap, but same problem.
I have tried to make swap not encrypted, but same problem.
I have tried to disable my nvidia card module, but same problem.
I have done fsck & badblock & memtest but no problem on disk & ram.
I have tried to play with dirty_pages and other sysctl variables but same
problem...


Please, some news about???


thanks

Comment 43 Maximilian Decker 2013-02-27 09:27:03 UTC
hi,

could you provide some step-by-step instruction on how to reliably reproduce the issue with current kernels ?
I guess the main point of this bug being kind of stale is its hard-to-trigger nature.
Well, and of course, decreasing developer interest as reiserfs3 is less often used in new installations.
But IMHO still a good fs with nice feature set, would love to see it around in a working state again...

dmesg for the oops

Hi:

 Unfortunately, I can't explain how to reliably reproduce this problem but this time it happenned quite soon as I upgraded to 3.8.0, exactly debian package linux-image-3.8-trunk-amd64 (3.8-1~experimental.1) The only thing I had to do was hibernate and after I resume the problem was already there.

  All partitions, but /boot are crypted. My disk and partition layout is this:

  I knew I triggered the problem when I tried to issue a "sync" command. But other options may be touching a file in a directory which is in the affected filesystem. I could recover from this situation doing a sysrq-E, which terminates all processes.

  I assume the best way to help is giving exact instructions to reproduce the crash but till I could get that information let me know if I can be of help some other way.

  This is an excerpt of the dmesg which I'm attaching:

Comment 45 Raúl 2013-05-11 15:03:36 UTC
Hi:

I've run into a series of locks of this kind. I can't add much more to what I've already reported. I haven't found a method of reliably reproduce this lock, my impression so far is that this one is related to:
a) wake up from suspend to ram (maybe also to disk) and 
b) certain /corruption/ layout in disk

Latest locks happened after I resume from ram. Disk was not much loaded at the lock moment, there was a high user activity though: like running and closing apps, email and an important amount of download threads in the background. I had the lock there.

As usual, the cleanest way to get out of this was alt-sysrq-E that terms all processes. Then three finger salute.

On a fresh boot, I tried the same usage pattern, soon after I had the lock again. In this case STR or STD (Suspend to Disk) weren't involved.

I decided to go into a reiserfsck --rebuild-tree in my home partition. This is a log excerpt:

I wonder if those "Unknown item type found" or several of those poiting to same block, e.g.: 205917185 mean anything or could trigger the unexpected lock.

As for me, I've never used suspend on the PC where the problem is present.

Yep, this is quite interesting, because usual startup file-system check doesn't report anything. Did the problem disappear after the file system had been repaired? 

However, yet I've bought new hard drive for that PC, and installed new OS and ext4, I still have old hard drive with the vulnerable reiserfs partition. I think it will be useful if I reach it and run --rebuild-tree in order to see my output.
Comment 47 Raúl 2013-05-11 15:51:00 UTC
I think rebuild-tree is more comprehensive than an usual --check or --fix-fixable and therefore is able to find (and fix) hidden (yet usable) problems.

Regarding definte repair, I wouldn't know yet. Lock could trigger after 5' or maybe after months, depeding on my usage pattern. I'll report back if the lock happens or after a reasonable time.
Regards,
Comment 48 Jeff Mahoney 2013-05-11 16:11:06 UTC
There are few misconceptions here about reiserfsck.

1) --rebuild-tree will not detect more problems than a --check will. It is the biggest, heaviest hammer we have in order to recover a file system and should not be used unless it absolutely must.

2) Only use --fix-fixable if you run into problems on the file system after mounting. The reason is that reiserfsck --check doesn't handle save links, which are placed in the file system when a file is truncated or removed while the file is still open. A file system with unhandled save links will have stat data that doesn't make sense right away and reiserfsck --check will suggest --fix-fixable as a result. I spent some time yesterday looking into how to fix this, but I'm not sure how to handle it gracefully WRT the system/disk/reiserfsck crashing mid-execution since it will essentially be operating directly on the file system without a journal for some fairly involved operations. So, for now, try to mount first. It'll replay the journal and clear the save links out.

---

I suspect that the root cause of these hangs is the reiserfs write lock not being dropped completely across schedules the way Frederic expected. I have a patch that makes the distinction between "dropping because we're done using it" and "dropping because we're scheduling" but I need to clean it up. I'll post it here tomorrow or Monday for testing.

Thanks a lot for fixing all these, Jeff!
Comment 53 David Kowis 2013-12-18 21:01:16 UTC
I'm uncertain if the problem I'm encountering is the same problem or not, but it appears extremely similar. Forgive me if I'm not contributing properly.

I've got a Xen VM that is exhibiting the locking symptoms, but not the corruption symptoms. A reiserfsck only replays journal entries and does not find any corruptions. This is the only VM that does this out of about 14 VMs. I see no error messages in the dom0 dmesg.

This is an ArchLinux distro Kernel 3.12.5-1-ARCH. it'll block anything that wants to do IO, the kworker here, and dropbox as well. Eventually it gets to the point that the system wedges and dies. I can Emergency Sync it via xl sysrq, but it won't shut down cleanly. I have to xl destroy it. My other VMs, some with higher IO loads are on 3.11.6-1-ARCH and have no problems.

Forgive me, I'm not using any quotas at least I don't have quotas enabled for mounting:

$ mount
/dev/xvda1 on / type reiserfs (rw,relatime)

$ dmesg | grep quota
[    0.378754] VFS: Disk quotas dquot_6.5.2

That does show up, but I believe that's simply because it's builtin.
Comment 55 D.K. 2013-12-20 22:41:59 UTC
I am also seeing what I believe to be an identical issue ( although it may not be ). In an attempt to make it reproducible I have written a C++ program to abuse a filesystem. I have been able to make the filesystem lock up after running the program for a few hours. I should be able to reproduce this fairly consistently so if there is some kind of information that will help in the troubleshooting process for other please let me know and I can try to get it for you. 

I am attaching my test program. 
The partition that is hanging is a PCI based SSD, but I have also seen this problem on a RAID array on Spinning circular media and on a VM mounted on a SAN. 

I have testing this with Kernel 3.2.28 and 3.12.2. I am currently compiling 3.12.5 and the tip of 3.12.y

Thanks. The trace shows that we:

1) Have threads queued up on i_mutex
2) Have threads queued up on queue_log_writer holding i_mutex
3) Have a thread queued up on queue_log_writer holding i_mutex and the page lock
4) Have a thread queued up on the page lock

Now to figure out what is causing the queue_log_writer condition to not continue.
Comment 61 D.K. 2014-01-06 18:45:34 UTC
So I see the changes in the kernel tree are slightly different from the ones in the patch. I imagine that was the result of review and testing so adding them back in won't change too much.
Comment 62 D.K. 2014-01-28 21:45:06 UTC
Turning off the journal ( via nolog ) does not appear to alter this behavior, and I have not been able to get this to be reproduced when turning on LOCKDEP.
Comment 63 D.K. 2014-02-04 20:20:44 UTC
Attached are two logs one is the output from LOCKDEP showing all locks held on a system. The second is the log showing all running tasks on the system when it locked up.

Comment 66 Hamdi Hamdi 2015-04-07 10:05:14 UTC
Hi,

After some research there is a scenario which triggered my suspicion (ref http://lxr.free-electrons.com/source/fs/reiserfs/journal.c?v=3.3):
	1) several threads call `queue_log_writer` and are put to sleep
	2) J_WRITERS_QUEUED bit is set
	3) `check_journal_end` returns nonzero value and the `do_journal_end` continues it's execution
	4) at line 4252 it clears the bit and wakes 1 thread
	5) no other thread enters `queue_log_writer` due to some unknown reason and the bit is not set again
	5) the awaken thread ends up with `if (!check_journal_end(th, sb, nblocks, flags)` 
		returning 0 which triggers the awakening of another thread
	6) No one will be awaken since there is no bit set on `if (test_and_clear_bit(J_WRITERS_QUEUED, &journal->j_state))`,
		except when the execution reaches line 4253

One ugly workaround for testing purposes at line 4253:
4253	wake_up(&(journal->j_join_wait));
	replaced with
4253	wake_up_all(&(journal->j_join_wait));

There must be a reason for this to happen on high loads only so any help and/or suggestions is more that welcome !
