Greetings everyone,
I've been having a bit of a problem since upgrading to the linux 3.x
series, I have a machine that we're using as a NAS that runs various
rsync processes (mostly at night), lately after a day or two, I will
come in in the morning to a load average of 49, but the machine not
really doing anything, when trying to run 'dstat' the command just
hung with no output at all. there were no errors in the logs, or even
anything that would vaguely point at anything I could work with.
So needing to get the machine back to work I attempted to reboot it
"shutdown -r now" on console... it gives a nice message saying it's
going to reboot, but nothing ever happens.. the only way to reboot it
is by using ctrl + alt + sysrq + b. after which the machine reboots
and the raid array comes back clean.
I'm not sure how to troubleshoot this, any pointers would be appreciated.
I'm compiling 3.2.4 at the moment and found a bunch of possibly useful
options in the kernel debugging section:
detect hard/soft lockups and detect hung tasks, maybe it'll give me
something more to go on.
Some details about the machine:
Linux xenbox 3.2.2 #1 SMP Sun Jan 29 10:28:22 CST 2012 x86_64 Intel(R)
Xeon(R) CPU 5140 @ 2.33GHz GenuineIntel GNU/Linux
It has 3 software raid arrays (2 x 5 drives and 1 x 4 drives) LVM'ed
together into a 23TB XFS filesystem.
6GB memory and a pair of Intel Gigabit ethernet controllers bonded together.

Also totally forgot, possibly quite important information, most of the
disks are connected via a pair of LSI controllers:
08:00.0 SCSI storage controller: LSI Logic / Symbios Logic SAS1068E
PCI-Express Fusion-MPT SAS (rev 08)
0a:00.0 RAID bus controller: LSI Logic / Symbios Logic MegaRAID SAS
2008 [Falcon] (rev 03)
a couple disks are connected with the onboard Intel SATA controller..

Hmm, might be some deadlock in the filesystem. Adding XFS guys to CC.
Can you run 'echo w >/proc/sysrq-trigger' and post output of dmesg here?

Thanks for the quick reply,
the machine is running good at the moment so I'm not sure if the
output helps, but here it is:
[I'll also be sure to grab this log the next time it locks]

Hi everyone,
It finally did it again, it took longer then I expected, it also
locked itself up so bad that I couldn't get into it to hit
ctrl+alt+sysrq+w ..
I had turned on the debugging feature that automatically logs the hung
tasks, and I've attached the log below, I hope it's helpful.
I was running 3.2.4 from kernel.org on a 4 core Xeon machine:
model name : Intel(R) Xeon(R) CPU 5140 @ 2.33GHz
6GB Ram
2x Intel 80003ES2LAN Gigabit Ethernet Controllers bonded together
2 LSI SAS controllers:
08:00.0 SCSI storage controller: LSI Logic / Symbios Logic SAS1068E
PCI-Express Fusion-MPT SAS (rev 08)
0a:00.0 RAID bus controller: LSI Logic / Symbios Logic MegaRAID SAS
2008 [Falcon] (rev 03)
16 drives in a mix of 2 and 3TB, in 3 raid5 arrays and combined
together with LVM
/dev/mapper/pool-main 23T 12T 11T 52%
for a 23TB volume formatted with XFS.
The root partition is ext4 on an older SATA drive, the reason I bring
this up is that when I hit (on a whim) ctrl+sysrq+J that is supposed
to unfreeze frozen filesystems, the console started dumping lots of
messages about attempting to unfreeze /dev/sda3 [my root partition] so
maybe there's a problem with my sda drive.
But I get no i/o or other errors in my logs at all. I monitor all
drives with smartd to head off any drive failures before they happen
and it seems to think sda is fine.
Hopefully my attached log helps.
I appreciate any input, also please call me an idiot if I'm missing
something obvious.

Thanks for the traces. I was looking at them and I don't see the
immediate problem. There is a task (kswapd0) reclaiming XFS inodes and
waiting for IO to complete. Quite some other tasks are waiting in
xfs_reclaim_inodes_ag() for reclaim mutex. Since some of them are called
from NFS code (e.g. nfs4_process_open1()), that seems to be a reason why
other tasks are blocked in nfs4_lock_state().
So all in all it seems like some problem in how mm does reclaim or we are
inefficient doing inode reclaim in XFS or for some reason the IO is too
slow. As a result we are low on memory and things go bad. Do you know with
which kernel version the problem started to appear?

We differ in terminology a bit but that's not really important when I
know what you mean :)

Yeah, interesting. There are no processes waiting for IO either so I'm
puzzled what causes you problems.

Well, apparently something uses it because fsnotify_mark thread is just
in the process of destroying some mark. Maybe you could run with
CONFIG_FSNOTIFY=n just to rule out some problems there...

Well, like the subject says this is a "soft lockup"..
When it happened the first time the system actually recovered
after some hours.
But like Gerard said, there is no apparent ground for this
unresponsiveness, there are tons of memory free and no swapping.

I have configured CONFIG_FSNOTIFY=y indeed but don't think I'm using it
from userspace..

Hmm, then this isn't really a deadlock (at least in your case) but only a
rather unresponsive system. Looking at the backtraces you provided I don't
see anything really suspicious. Only maybe fsnotify_mark process - do you
use fsnotify?

Thanks for report.
