Load on server during reset problem
Patch to correct resets

Description Anthony Hausman 2018-04-18 08:19:04 UTC 
I'm using the kernel 4.11.0-14-generic with the last hpsa driver compile from the last commit of torvalds github :

https://github.com/torvalds/linux/commit/8b834bff1b73dce46f4e9f5e84af6f73fed8b0ef#diff-7a84fb366ebc08b575a832f0aeee3434

I'm using a Smart Array P420i, Firmware Version 8.32.
When a resetting logical is triggered, this one never complete and the server start to have a heavy load (can rise to 3000).
After the reset, some task begin to timout but I think that is just the effect of the resetting (cmaeventd is the process checking for controller status):

The only way to be back to normal is to reboot the server. 
Hope this helps somebody. If there is any more info I can provide, just ask what would be useful.
Comment 1 Don 2018-04-18 14:27:07 UTC 
Do you see any lockup messages in the console logs?
"Controller lockup detected"...


The driver you used is from 4.16 kernel on a 4.11 kernel? I have not tested this configuration.

I notice that the driver is still using the kernel work-queue for monitoring. I will be sending up a patch to change this to local work-queues soon. Perhaps you can test this patch? It may help to discover more information on what is happening.

Also, after you rebooted, were there any lockup entries in the ilo IML log?
Comment 2 Anthony Hausman 2018-04-18 14:38:22 UTC 
I don't have any "Controller lockup detected" message in the Syslog unfortunately.
On the ilo IML log, the last message was about the cache module:

CAUTION: POST Messages - POST Error: 1792-Slot X Drive Array - Valid Data Found in Cache Module. Data will automatically be written to drive array..

I have nothing about lockup entries.

Indeed, we use the driver from the last kernel and compiled it for 4.11.
I am ready to test the patch you are proposing. 
Where can I retrieve it?
Comment 3 Don 2018-04-18 17:26:11 UTC 
Created attachment 275437 [details]
Patch to use local work-queue insead of system work-queue

If the driver initiates a re-scan from a system work-queue, the kernel can hang.

This patch has not been submitted to linux-scsi, I will be sending this patch out soon.
Comment 4 Don 2018-04-18 17:28:13 UTC 
Your stack trace does not show and hpsa driver components, but I do see the reset issued but not completing.

I'm hoping that the attached patch helps diagnose the issue a little better.
Comment 5 Anthony Hausman 2018-04-19 09:11:42 UTC 
Don,

I have applied the patch, it actually run and I try to reproduce the problem.
I'll inform you about the diagnose.
Comment 6 Anthony Hausman 2018-04-19 10:35:28 UTC

And once again, it has caused nothing on the server, no offline or critical disk return by hpsa utilities or heavy load.
But it directly concerns the hpsa module and the workqueue.
Comment 8 Anthony Hausman 2018-04-21 08:12:48 UTC 
So I have reproduced the problem with the patch driver.
At the beginning, one disk return a lot of blk_update_request: critical medium error/Unrecovered read error and after the driver trigger a reset logical on all disk.

At the first trigger, all reset completed successfully but the third reset on the problematic error disk the system hang out and the reset never complete.

The load on the server is less important at that time but application seems to stuck their IO still.
And the faulty disk is still considered healthy via the hp utilitues (ssacli).

Here is the stack trace:

When you applied the 4.16 hpsa driver patches, was this patch also applied?

    genirq/affinity: assign vectors to all possible CPUs
    
    Currently we assign managed interrupt vectors to all present CPUs.  This
    works fine for systems were we only online/offline CPUs.  But in case of
    systems that support physical CPU hotplug (or the virtualized version of
    it) this means the additional CPUs covered for in the ACPI tables or on
    the command line are not catered for.  To fix this we'd either need to
    introduce new hotplug CPU states just for this case, or we can start
    assining vectors to possible but not present CPUs.

The above patch is why the hpsa-fix-selection-of-reply-queue patch was needed.
If not, I would redact that patch because it may be causing your issues.


There was another patch required for the hpsa-fix-selection-of-reply-queue patch:
scsi-introduce-force-blk-mq.


The errors shown in your logs indicate issues with DMA transfers of your data.
Unaligned partial completion errors are usually issues with the scatter/gather
buffers that represent your data buffers. I would like to eliminate using
the 4.16 hpsa driver in a 4.11 kernel.

Can you try our out-of-box driver?

I'll attach this to the BZ. You compile it with make -f Makefile.alt
The name is hpsa-3.4.20-136.tar.bz2

    scsi: hpsa: fix selection of reply queue
    
    Since commit 84676c1f21e8 ("genirq/affinity: assign vectors to all
    possible CPUs") we could end up with an MSI-X vector that did not have
    any online CPUs mapped. This would lead to I/O hangs since there was no
    CPU to receive the completion.
    
    Retrieve IRQ affinity information using pci_irq_get_affinity() and use
    this mapping to choose a reply queue.

    scsi: introduce force_blk_mq
    
    From scsi driver view, it is a bit troublesome to support both blk-mq
    and non-blk-mq at the same time, especially when drivers need to support
    multi hw-queue.
    
    This patch introduces 'force_blk_mq' to scsi_host_template so that drivers
    can provide blk-mq only support, so driver code can avoid the trouble
    for supporting both.

Latest out of box hpsa driver.

This tar file contains our latest out-of-box driver.

1. tar xf hpsa-3.4.20-136.tar.bz2
2. cd hpsa-3.4.20/drivers/scsi
3. make -f Makefile.alt

If you are booted from hpsa, you will need to update your initrd and reboot.

If you are using hpsa for non-boot drives, your can

Comment 11 Anthony Hausman 2018-04-22 10:12:57 UTC 
The only patch that I'm sure that I have is the "scsi: hpsa: fix selection of reply queue" one.
For the I'm using an out of the box 4.11 kernel. So I'm really not sure that the other patches are present.


Unfortunately, the module does not compile using 4.11.0-14-generic headers.

But if you tell me the principal problem is using the 4.11 kernel, I can upgrade it to use the 4.16.3 kernel.

If I use it, must I use the out of box 3.4.20-136 hpsa driver or use your precedent patch on the last 3.4.20-125?
Comment 12 loberman 2018-04-22 18:38:13 UTC 
We had a bunch of issues with the HPSA as already mentioned above.
The specific issue that we had to revert was this commit
8b834bff1b73dce46f4e9f5e84af6f73fed8b0ef


I assume your array has a charged battery (capacitor) and the writeback-cache is enabled on the 420i

Are you only seeing this wen you have cmaeventd running, because hat can use pass through commands and has been known to cause issues.
I am not running any of the HPE Proliant SPP daemons on my system.

I have not seen this load related issue (without those daemons running) that you are seeing on my DL380G7 or Dl380G8 here so I will work on trying to reproduce and assist.

Thanks
Laurence

Comment 14 Anthony Hausman 2018-04-23 09:07:51 UTC 
Indeed I have a charged battery (capacitor) and the writeback-cache enabled.
I run the hp-health component too, I have already try to disable it on the 4.11 kernel and have reproduced the problem of load without it.

The cma related call trace up after the logical drive reset is called.

Right now, I test on a server the kernel 4.16.3-041603-generic with the hpsa module with the patch to use local work-queue insead of system work-queue.

Right now I didn't reproduce the problem.
I had a disk with bad blocks (before launching a read-only test badblocks returned a lot of block error) but since I have upgraded the kernel with the patch hpsa module I have no more error.

I'm still trying to reproduce the problem by launching a badblocks read-only test on the "ex-faulty" disk.

I'll tell you the result of the test.

The 4.16.3 driver should be OK to use.

You could not untar the sources I gave you in /tmp and build with make -f Makefile.alt?

If you copy the source code into the kernel tree, you should be able to do
make modules SUBDIRS=drivers/scsi hpsa.ko
Comment 16 Anthony Hausman 2018-04-25 08:37:42 UTC 
Don,

So I'm actually running the kernel 4.16.3 (build 18-04-19) with the hpsa modules patch to use local work-queue insead of system work-queue.

I have a reproduce a reset with no stack trace (which is a good news).
The only thing is between the resetting logical and the completation, 2 hours passed and caused an heavy load on the server during this time:

Apr 25 01:31:09 kernel: hpsa 0000:08:00.0: scsi 0:1:0:0: resetting logical  Direct-Access     HP       LOGICAL VOLUME   RAID-0 SSDSmartPathCap- En- Exp=1

The good thing after the reset has completed, this one is removed:

Apr 25 03:31:48 kernel: scsi 0:1:0:0: rejecting I/O to dead device

So the question is if it's normal than the reset logical take such a long time (and causing trouble on the server)?

The driver was notified by the P420i that the volume went offline, so the driver removed it from SML.

> Apr 25 03:31:48 kernel: scsi 0:1:0:0: rejecting I/O to dead device

There were I/O requests for the device, but the SML detected that it was deleted.

It is not normal.

For a Logical Volume reset, the P420i flushes out any outstanding I/O requests then returns. The SML should block any new requests from coming down while the reset is in progress.

Do you know what process was consuming the CPU cycles?
ps -deo psr,pid,cls,cmd:50,pmem,size,vsz,nice,psr,pcpu,wchan:30,comm:30 | sort -nk1 | head -20

Are your using sg_reset to test LV resets? Or, does the device have some intermittent issues which is causing the SML to issue the reset operation?

If you turn off the agents, do the resets complete more quickly?

I am wondering if the agents are frequently probing the P420i for changes when the reset is active and the agents are consuming the CPU cycles.
Comment 18 Anthony Hausman 2018-04-25 15:06:42 UTC 
Unfortunatly I don't know what process was consuming the CPU cycles at this.
I'll try to reproduce the problem to reproduce the problem to have the information.

I'm not using sg_reset to test the lv reset, actually I am launching a badblocks command on a problematic disk and the reset is invoked when it begins to fails.

I'll use sg_reset to reproduce the problem and test with/without the agent.
I invoke the agent every 5 minutes to check the controller and disks states.

I keep you inform on my test.

By the way, I thank you for your help.
Comment 19 loberman 2018-04-25 15:09:52 UTC 
I was concerned about the agents but Anthony disabled them and still saw this.I have seen this timeout sometimes when the agents probe via passthrough.

I did just bump into this reset on a 7.5 RHEL kernel with no agents but it recovered almost immediately.
I need to chase that down
Comment 20 Anthony Hausman 2018-04-26 12:42:59 UTC 
So here are all my test.
With the agent enable, using hp check command disk (hpacucli/ssacli and hpssacli) and launching a sg_reset, the reset has no problem on the problematic disk:

Apr 26 14:31:20 kernel: hpsa 0000:08:00.0: scsi 0:1:0:0: resetting logical  Direct-Access     HP       LOGICAL VOLUME   RAID-0 SSDSmartPathCap- En- Exp=1
Apr 26 14:31:21 kernel: hpsa 0000:08:00.0: device is ready.

The reset only took 1 second.

The "bug" seems to appear only when the disk returns errors concerning Unrecovered read error (when using badblocks read-only test by example).

I try to reproduce it.
Comment 21 Anthony Hausman 2018-05-02 08:46:17 UTC 
I have reproduced the problem.
Here the condition that I have done:

Kernel: 4.16.3-041603-generic
hpsa: 3.4.20-125 with patch to use local work-queue instead of system work-queue.

I needed to execute a badblocks in a read-only test on a disk who has failed before:

~# while :; do badblocks -v -b 4096 -s /dev/sdt; done

And several days after, the bug raised.
You'll find a graph of the load in an attachment.
Before the reset, I have a hpsa_update_device_info: inquiry failed and a stack trace on badblocks (this one seems to be logical)

Load: 850

So here it is, I hope we have now enough thing to track down this weird behavior.

If you need some other informations or more thing, I can make a little to script to pass some commands if the reset raise without returns.

Same behavior here with controllers P440ar and P420i on DL480 G8 and DL480p G8.

Firmware:
  - P440ar: 6.60
  - P420i: 8.32

Comment 26 Gaetan Trellu 2018-10-15 14:12:57 UTC 
Moved from Ubuntu 16.04.5 to CentOS 7.5 with hpsa kernel module (kmod-hpsa-3.4.20-141.rhel7u5.x86_64.rpm) from HPE website.

Running without kernel panic since more than a week.
Comment 27 Gaetan Trellu 2018-12-06 17:25:21 UTC 
By compiling the hpsa kernel module from SourceForge on Ubuntu 16.04 with kernel 4.4 solved the issue for us.

Steps:
# apt-get install dkms build-essential
# tar xjvf hpsa-3.4.20-141.tar.bz2
# cd hpsa-3.4.20/drivers/
# sudo cp -a scsi /usr/src/hpsa-3.4.20.141
# dkms add -m hpsa -v 3.4.20.141
# dkms build -m hpsa -v 3.4.20.141
# dkms install -m hpsa -v 3.4.20.141

Comment 28 Anthony Hausman 2019-01-23 15:16:01 UTC 
I have actually compiled the hpsa driver 3.4.20.141 into the kernel 4.19.13.

I still have the same behavior, a heavy load (3000) and all disk of the controller unavailable.

But this time, it's not the reset who trigger the bug, here the log that I have.

First of all, one disk returns a lot of critical medium error:
```

Comment 29 Gaetan Trellu 2019-01-24 16:24:18 UTC 
The issue came back too...

The only way so for to avoid the crashes has been to switch the card from RAID to HBA but at performances cost.
Comment 30 Don 2019-03-22 19:43:52 UTC 
I have been re-writing the eh_reset path recently.

I found a race condition between the completion handler and the reset handler.

I have an update that I have been aggressively testing that seems to be holding up.

I am testing using 7 volumes: 2 SAS HBAs, 2 SATA HBAs, 1 Smart Path enabled R5, and 2 LVs.

My tests consist of issuing resets (sg_reset -d) to all volumes repeatedly while doing:
1. mke2fs to all 7 in parallel
2. mount all volumes in parallel
3. rsync data to all volumes in parallel
4. umount all volumes in parallel
5. fsck all volumes in parallel.

Before my update, I was having the above issue.

I intend to run the above tests over the weekend, then submit the update internally for code review/testing before I send the update to kernel.org.

Thanks,
Don Brace

Super news Don, 
Please, let me know when the patch/update will be available. I'm interested to test it.

Thanks and regards,

Patch to correct resets

    hpsa: correct device resets
    
    - Correct a race condition that occurs between the
      reset handler and the completion handler. There
      are times when the wait_event condition is never
      met due to this race condition and the reset never
      completes.
    
      The reset_pending field is NULL initially.
    
      t  Reset Handler Thread     Completion Thread
      -- --------------------     -----------------
      t1                          if (c->reset_pending)
      t2 c->reset_pending = dev;     if (atomic_dev_and_test(counter))
      t3 atomic_inc(counter)             wait_up_all(event_sync_wait_queue)
      t4
      t5 wait_event(...counter == 0)
    
    Kernel.org Bugzilla:
               https://bugzilla.kernel.org/show_bug.cgi?id=1994350
               Bug 199435 - HPSA + P420i resetting logical Direct-Access
                            never complete
    

Here is the patch I am preparing to send up to kernel.org. I have been testing this patch for some time now and I feel it is ready.
Comment 33 Anthony Hausman 2019-05-07 08:39:23 UTC 
Hi Don,

Did you send it to kernel.org?
Any idea when the patch will be available in the kernel?

Is the patch compatible with the last kernel longterm release 4.19?

Thanks in advance for your response.

I will be sending the patch up today.

It will apply if all of the patches I am sending up are applied. 
Otherwise it will have to have some minor porting done to have it applied.

The patches I am sending up are:

hpsa-correct-simple-mode
hpsa-use-local-workqueues-instead-of-system-workqueues
hpsa-check-for-tag-collision
hpsa-wait-longer-for-ptraid-commands
hpsa-do-not-complete-cmds-for-deleted-devices
hpsa-correct-device-resets
hpsa-update-driver-version

I have similar (exact the same?) problem with HPSA P410 already on two of my nodes with Kernel 5.7.1-1.el7.elrepo.x86_64

Here are the logs:
