md data-check causes soft lockup

Linux software RAID maintainers and developers,

Two months ago I wrote to the Linux kernel mailing list regarding a condition expressed as "BUG: soft lockup - CPU#3 stuck for 61s!". I initially battled this recurring problem in both Fedora 10 and Fedora 11. Rafael J. Wysocki suggested that I update the kernel (to 2.6.31-rc4 or later) and see if the problem resurfaced. I then used kernel 2.6.31-0.94.rc4.fc12.x86_64 and found that the problem still continued, but noticeably only when the md data-check process was run.

You can read the last post to the LKML thread (with links to the entire thread) here:

http://lkml.org/lkml/2009/8/6/387

The md data-check is being run in Fedora 11 by /etc/cron.weekly/raid-check which is a little shell script that looks like this:

------------------------------------------------------
#!/bin/bash

for dev in grep "^md.*: active" /proc/mdstat | cut -f 1 -d ' '; do
[ -f /sys/block/$dev/md/sync_action ] && \
echo "check" > /sys/block/$dev/md/sync_action
done
------------------------------------------------------

I have disabled this weekly data-check, and since doing so have not encountered any soft lockup (or any other problem, for that matter).

For reference, you can see in this thread here that I am not the only one to have this problem:

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/212684

It may important to note that I am running a 4-disk RAID1 array on 500GB Western-Digial SATA drives. I've attached the output of 'lspci -vv' as "lspci.out". I've attached the output of 'hdparm -I /dev/sda' as "hdparm.out". /dev/sda, /dev/sdb, /dev/sdc, and /dev/sdd are all identical drive types. I've attached the output of 'for i in 0 1 2; do mdadm --detail /dev/md$i; done' as "mdadm.out".

Please let me know if this is a configuration problem, a kernel bug, or something else. Please let me know how to fix this problem so that I can safely re-enable md data-check.

Thanks,

Lee.

Hello,

Check out the thread with the subject: BUG: soft lockup in [md4_raid5:21137]

I think the guys have already fixed this in 2.6.32. The patch is mentioned in one of the replies, if you wish to try it.

Quoted 892 lines · Lee Howard

Linux software RAID maintainers and developers,
Two months ago I wrote to the Linux kernel mailing list regarding a condition expressed as "BUG: soft lockup - CPU#3 stuck for 61s!". I initially battled this recurring problem in both Fedora 10 and Fedora 11. Rafael J. Wysocki suggested that I update the kernel (to 2.6.31-rc4 or later) and see if the problem resurfaced. I then used kernel 2.6.31-0.94.rc4.fc12.x86_64 and found that the problem still continued, but noticeably only when the md data-check process was run.
You can read the last post to the LKML thread (with links to the entire thread) here:
http://lkml.org/lkml/2009/8/6/387
The md data-check is being run in Fedora 11 by /etc/cron.weekly/raid-check which is a little shell script that looks like this:
------------------------------------------------------
#!/bin/bash
for dev in grep "^md.*: active" /proc/mdstat | cut -f 1 -d ' '; do [ -f /sys/block/$dev/md/sync_action ] && \
echo "check" > /sys/block/$dev/md/sync_action done
------------------------------------------------------
I have disabled this weekly data-check, and since doing so have not encountered any soft lockup (or any other problem, for that matter).
For reference, you can see in this thread here that I am not the only one to have this problem:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/212684
It may important to note that I am running a 4-disk RAID1 array on 500GB Western-Digial SATA drives. I've attached the output of 'lspci -vv' as "lspci.out". I've attached the output of 'hdparm -I /dev/sda' as "hdparm.out". /dev/sda, /dev/sdb, /dev/sdc, and /dev/sdd are all identical drive types. I've attached the output of 'for i in 0 1 2; do mdadm --detail /dev/md$i; done' as "mdadm.out".
Please let me know if this is a configuration problem, a kernel bug, or something else. Please let me know how to fix this problem so that I can safely re-enable md data-check.
Thanks,
Lee.

Linux software RAID maintainers and developers,
Two months ago I wrote to the Linux kernel mailing list regarding a condition expressed as "BUG: soft lockup - CPU#3 stuck for 61s!". [...CUT...]

I also have seen this problem, on our new server with Ubuntu karmic alpha1 with ubuntu kernel 2.6.31-5-server (this is not a stable 2.6.31, dunno to which release candidate it corresponds exactly) reproducible if I set high stripe cache size of 1024 or higher, while performing "check" as you report.

The problem starts with stripe_cache_size around 512 for our mdadm raid-6 with 26 drives, already gives a noticeable starvation of disk accesses. The higher you set it, the more reproducible is the problem, and the longer the starvation time. At 1024 seems already 100% reproducible and the starvation time seems endless already, I tried up to 32768. 256 seems safe.

All disk activity on the RAID is completely stuck while performing check. I mean endless starvation on disk access for high stripe_cache_sizes. Luckily one can stop the check, lower the stripe_cache_size, then start the check again.

This is the dmesg error for me while on soft lockup (appearing periodically on various CPUs.)

I have just checked and the same problem happens on our older server with Ubuntu Hardy 2.6.24-22-openvz, but only at stripe_cache_size 32768. Consider it's a smaller RAID-6 there, 12 devices. At lower stripe_cache_sizes I only see a very long wait time for whatever application tries to access the disk, such as vi trying to write the file. Both servers have really plenty of RAM. The older server is a dual-xeon 5345, the new one is a dual-xeon-5420.

This is the dmesg for the older server:

The bug can be workarounded by setting a resync_speed_max which is lower than what the hardware is capable of. Or by lowering the stripe_cache_size as I said.

Thank you MD people for looking into this problem.

In reply to Majed B.

Thanks Majed,

I've looked at the patch and it modifies md/raid5.c. However, I'm using RAID1. Am I ignorant for doubting that the patch to raid5.c has any affect on RAID1?

Thanks,

Lee.

Hello,
Check out the thread with the subject: BUG: soft lockup in [md4_raid5:21137]
I think the guys have already fixed this in 2.6.32. The patch is mentioned in one of the replies, if you wish to try it.
Quoted 893 lines · Lee Howard
Linux software RAID maintainers and developers,
Two months ago I wrote to the Linux kernel mailing list regarding a condition expressed as "BUG: soft lockup - CPU#3 stuck for 61s!". I initially battled this recurring problem in both Fedora 10 and Fedora 11.
Rafael J. Wysocki suggested that I update the kernel (to 2.6.31-rc4 or
later) and see if the problem resurfaced. I then used kernel 2.6.31-0.94.rc4.fc12.x86_64 and found that the problem still continued, but noticeably only when the md data-check process was run.
You can read the last post to the LKML thread (with links to the entire thread) here:
http://lkml.org/lkml/2009/8/6/387
The md data-check is being run in Fedora 11 by /etc/cron.weekly/raid-check which is a little shell script that looks like this:
------------------------------------------------------
#!/bin/bash
for dev in grep "^md.*: active" /proc/mdstat | cut -f 1 -d ' '; do
[ -f /sys/block/$dev/md/sync_action ] && \
echo "check" > /sys/block/$dev/md/sync_action
done
------------------------------------------------------
I have disabled this weekly data-check, and since doing so have not encountered any soft lockup (or any other problem, for that matter).
For reference, you can see in this thread here that I am not the only one to have this problem:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/212684
It may important to note that I am running a 4-disk RAID1 array on 500GB Western-Digial SATA drives. I've attached the output of 'lspci -vv' as "lspci.out". I've attached the output of 'hdparm -I /dev/sda' as "hdparm.out". /dev/sda, /dev/sdb, /dev/sdc, and /dev/sdd are all identical drive types. I've attached the output of 'for i in 0 1 2; do mdadm --detail /dev/md$i; done' as "mdadm.out".
Please let me know if this is a configuration problem, a kernel bug, or something else. Please let me know how to fix this problem so that I can safely re-enable md data-check.
Thanks,
Lee.

I must have missed that part. It may not work for your case, but worth trying.

Perhaps Neil Brown, or someone involved could shed some light on this.

If I remember correctly, those soft lockups were harmless anyway.

Thanks Majed,
I've looked at the patch and it modifies md/raid5.c. However, I'm using RAID1. Am I ignorant for doubting that the patch to raid5.c has any affect on RAID1?
Thanks,
Lee.

Hello,
Check out the thread with the subject: BUG: soft lockup in [md4_raid5:21137]
I think the guys have already fixed this in 2.6.32. The patch is mentioned in one of the replies, if you wish to try it.
Quoted 910 lines · Lee Howard
Linux software RAID maintainers and developers,
Two months ago I wrote to the Linux kernel mailing list regarding a condition expressed as "BUG: soft lockup - CPU#3 stuck for 61s!". I initially battled this recurring problem in both Fedora 10 and Fedora 11. Rafael J. Wysocki suggested that I update the kernel (to 2.6.31-rc4 or later) and see if the problem resurfaced. I then used kernel 2.6.31-0.94.rc4.fc12.x86_64 and found that the problem still continued, but
noticeably only when the md data-check process was run.
You can read the last post to the LKML thread (with links to the entire thread) here:
http://lkml.org/lkml/2009/8/6/387
The md data-check is being run in Fedora 11 by /etc/cron.weekly/raid-check
which is a little shell script that looks like this:
------------------------------------------------------
#!/bin/bash
for dev in grep "^md.*: active" /proc/mdstat | cut -f 1 -d ' '; do [ -f /sys/block/$dev/md/sync_action ] && \
echo "check" > /sys/block/$dev/md/sync_action done
------------------------------------------------------
I have disabled this weekly data-check, and since doing so have not encountered any soft lockup (or any other problem, for that matter).
For reference, you can see in this thread here that I am not the only one to
have this problem:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/212684
It may important to note that I am running a 4-disk RAID1 array on 500GB Western-Digial SATA drives. I've attached the output of 'lspci -vv' as "lspci.out". I've attached the output of 'hdparm -I /dev/sda' as "hdparm.out". /dev/sda, /dev/sdb, /dev/sdc, and /dev/sdd are all identical
drive types. I've attached the output of 'for i in 0 1 2; do mdadm --detail
/dev/md$i; done' as "mdadm.out".
Please let me know if this is a configuration problem, a kernel bug, or something else. Please let me know how to fix this problem so that I can safely re-enable md data-check.
Thanks,
Lee.

I must have missed that part. It may not work for your case, but worth trying.
Perhaps Neil Brown, or someone involved could shed some light on this.
If I remember correctly, those soft lockups were harmless anyway.

Not harmless for production use. Yes, data is not harmed, and yes, the problem state does recover when the data-check finishes, but during the data-check the system is virtually unresponsive and all other use of the system is stalled.

Thanks,

Lee.

Thanks Majed,
I've looked at the patch and it modifies md/raid5.c. However, I'm using RAID1. Am I ignorant for doubting that the patch to raid5.c has any affect on RAID1?
Thanks,
Lee.

Hello,
Check out the thread with the subject: BUG: soft lockup in [md4_raid5:21137]
I think the guys have already fixed this in 2.6.32. The patch is mentioned in one of the replies, if you wish to try it.
Quoted 910 lines · Lee Howard
Linux software RAID maintainers and developers,
Two months ago I wrote to the Linux kernel mailing list regarding a condition expressed as "BUG: soft lockup - CPU#3 stuck for 61s!". I initially battled this recurring problem in both Fedora 10 and Fedora 11.
Rafael J. Wysocki suggested that I update the kernel (to 2.6.31-rc4 or
later) and see if the problem resurfaced. I then used kernel 2.6.31-0.94.rc4.fc12.x86_64 and found that the problem still continued, but
noticeably only when the md data-check process was run.
You can read the last post to the LKML thread (with links to the entire thread) here:
http://lkml.org/lkml/2009/8/6/387
The md data-check is being run in Fedora 11 by /etc/cron.weekly/raid-check
which is a little shell script that looks like this:
------------------------------------------------------
#!/bin/bash
for dev in grep "^md.*: active" /proc/mdstat | cut -f 1 -d ' '; do
[ -f /sys/block/$dev/md/sync_action ] && \
echo "check" > /sys/block/$dev/md/sync_action
done
------------------------------------------------------
I have disabled this weekly data-check, and since doing so have not encountered any soft lockup (or any other problem, for that matter).
For reference, you can see in this thread here that I am not the only one to
have this problem:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/212684
It may important to note that I am running a 4-disk RAID1 array on 500GB Western-Digial SATA drives. I've attached the output of 'lspci -vv' as "lspci.out". I've attached the output of 'hdparm -I /dev/sda' as "hdparm.out". /dev/sda, /dev/sdb, /dev/sdc, and /dev/sdd are all identical
drive types. I've attached the output of 'for i in 0 1 2; do mdadm --detail
/dev/md$i; done' as "mdadm.out".
Please let me know if this is a configuration problem, a kernel bug, or something else. Please let me know how to fix this problem so that I can safely re-enable md data-check.
Thanks,
Lee.

Have you tried attaching the checking process to a specific CPU/Core? It's called Affinity.

Also, did you try to reduce the numbers in: /proc/sys/dev/raid/speed_limit_min

Keep it as low as possible, and md should drop to that number (I think it's in kB) when the system is being utilized, then go back to /proc/sys/dev/raid/speed_limit_max when it's idle.

I must have missed that part. It may not work for your case, but worth trying.
Perhaps Neil Brown, or someone involved could shed some light on this.
If I remember correctly, those soft lockups were harmless anyway.
Not harmless for production use. Yes, data is not harmed, and yes, the problem state does recover when the data-check finishes, but during the data-check the system is virtually unresponsive and all other use of the system is stalled.
Thanks,
Lee.

Thanks Majed,
I've looked at the patch and it modifies md/raid5.c. However, I'm using RAID1. Am I ignorant for doubting that the patch to raid5.c has any affect
on RAID1?
Thanks,
Lee.

Hello,
Check out the thread with the subject: BUG: soft lockup in [md4_raid5:21137]
I think the guys have already fixed this in 2.6.32. The patch is mentioned in one of the replies, if you wish to try it.
Quoted 968 lines · Lee Howard
Linux software RAID maintainers and developers,
Two months ago I wrote to the Linux kernel mailing list regarding a condition expressed as "BUG: soft lockup - CPU#3 stuck for 61s!". I initially battled this recurring problem in both Fedora 10 and Fedora 11.
Rafael J. Wysocki suggested that I update the kernel (to 2.6.31-rc4 or later) and see if the problem resurfaced. I then used kernel 2.6.31-0.94.rc4.fc12.x86_64 and found that the problem still continued, but
noticeably only when the md data-check process was run.
You can read the last post to the LKML thread (with links to the entire thread) here:
http://lkml.org/lkml/2009/8/6/387
The md data-check is being run in Fedora 11 by /etc/cron.weekly/raid-check
which is a little shell script that looks like this:
------------------------------------------------------
#!/bin/bash
for dev in grep "^md.*: active" /proc/mdstat | cut -f 1 -d ' '; do [ -f /sys/block/$dev/md/sync_action ] && \
echo "check" > /sys/block/$dev/md/sync_action done
------------------------------------------------------
I have disabled this weekly data-check, and since doing so have not encountered any soft lockup (or any other problem, for that matter).
For reference, you can see in this thread here that I am not the only one
to
have this problem:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/212684
It may important to note that I am running a 4-disk RAID1 array on 500GB
Western-Digial SATA drives. I've attached the output of 'lspci -vv' as "lspci.out". I've attached the output of 'hdparm -I /dev/sda' as "hdparm.out". /dev/sda, /dev/sdb, /dev/sdc, and /dev/sdd are all identical
drive types. I've attached the output of 'for i in 0 1 2; do mdadm --detail
/dev/md$i; done' as "mdadm.out".
Please let me know if this is a configuration problem, a kernel bug, or something else. Please let me know how to fix this problem so that I can
safely re-enable md data-check.
Thanks,
Lee.

I must have missed that part. It may not work for your case, but worth trying.
Perhaps Neil Brown, or someone involved could shed some light on this.

If I remember correctly, those soft lockups were harmless anyway.
Not harmless for production use. Yes, data is not harmed, and yes, the problem state does recover when the data-check finishes, but during the data-check the system is virtually unresponsive and all other use of the system is stalled.

Are you sure this is caused by these soft lockups, and that you're not just running with too high a /sys/block/mdX/md/sync_speed_max setting? I've had issues with this on some servers, where the I/O demand for the sync/check is causing the system to become totally unresponsive.

Cheers,
Robin

That's correct for me in the sense that lowering sync_speed_max solves the problem, see my post, however I'd call it a bug if a value of sync_speed_max too high starves the system forever. The resync is supposed to be less prioritarian than normal I/O disk operations, but it doesn't happen this way. Also note that lowering the value of stripe_cache_size also solves the problem: how would this fit into your reasoning?

(BTW I have not checked the mentioned patch yet, I'm not sure I can do that in a short time because our servers are into production now)

Why would you lower the max value? You should keep the min value as low as possible and md would drop to that automatically if there are applications demanding access to the array.

But if the applications are locked out, they can't demand anything. I have seen the same on my Linux server, but only with the 2.6 kernel. The same hardware with a 2.4 kernel was fine. I have not seen this myself for at least 1 year, I assumed it was fixed.

When I was locked out my putty session would not respond. I don't think it timed out, but recovered when the rebuild/resync was done.

Linux software RAID maintainers and developers,
Two months ago I wrote to the Linux kernel mailing list regarding a condition expressed as "BUG: soft lockup - CPU#3 stuck for 61s!". I initially battled this recurring problem in both Fedora 10 and Fedora
11. Rafael J. Wysocki suggested that I update the kernel (to 2.6.31-rc4 or later) and see if the problem resurfaced. I then used kernel 2.6.31-0.94.rc4.fc12.x86_64 and found that the problem still continued, but noticeably only when the md data-check process was run.

You can read the last post to the LKML thread (with links to the entire thread) here:
http://lkml.org/lkml/2009/8/6/387

Thanks for the report.

It looks like the difference between the cpu/RAM speed and the drive speed is small enough that the CPU gets stuck comparing lots of blocks for multiple seconds.

This patch should fix it. I'll see that it goes upstream.

This patch...

Dear Neil,

as you can see I reported a similar problem for raid-6 in this thread. Your patch apparently covers raid-1. Is it because this other patch
http://osdir.com/ml/linux-raid/2009-09/msg00371.html
covers my case? it's all fixed then?

Thank you

Yes and yes .... unless there is a similar problem with raid10... OK, I just added the same fix for RAID10 so it should all be fixed (once these patches get upstream).
