Package: linux-image-3.2.0-4-amd64
Version: 3.2.46-1
Hello,
During extensive testing of NFS4 file server (Debian 7 guest on VMware / Proxmox VE-KVM) that shares
XFS filesystems over network we've hit problem with occasional system hangups caused by nfsd and
xfsaild processes.
When this issue occurs, 2 from 4 cpus are 100% loaded (one with nfsd, second with xfsaild) and two
other CPU-s are trying to handle other processes but i/o wait is almost 100% for those CPU-s and
system is unusable (sometimes it's possible to ssh into system after long waiting, sometimes it's
not possible; scp seems to work better in this situation, console is always blank and unresponsible,
pings work ok).

See attached /proc/sched_debug dump from "hangup" time, that indicates nfsd and xfsaild as cpu0 and
cpu3 holders.
We've managed to recreate this issue a few times (every test requred VM restoring from backup and
6-24 hours of intensive NFS operations to hit hangup) and every time xfsaild proces in sched_debug
was connected with dm-5 device on our system (see xfsaild/dm-5 in attached sched_debug dump).
The very last messages that syslog managed to send to remote syslog server were always like in
attached syslog.txt extract.
Device dm-5 was bound to XFS filesystem with high agcount (agcount=81 was effect of growing this FS
from small to bigger size); xfs_info output for this FS:
meta-data=/dev/mapper/vg1-tmp isize=256 agcount=81, agsize=16320 blks
= sectsz=512 attr=2
data = bsize=4096 blocks=1310720, imaxpct=25
= sunit=64 swidth=128 blks
naming =version 2 bsize=4096 ascii-ci=0
log =internal bsize=4096 blocks=1216, version=2
= sectsz=512 sunit=64 blks, lazy-count=1
realtime =none extsz=4096 blocks=0, rtextents=0
After reformatting this XFS filesystem (agcount=4 after reformatting) and repeating tests, we didn't
manage to hit this issue any more, so problem may be connected with XFS and high agcount and
intensive operations on such XFS filesystem (maybe some races in kernel code near XFS?).

Hi
This bug was filed for a very old kernel or the bug is old itself
without resolution.
If you can reproduce it with
- the current version in unstable/testing
- the latest kernel from backports
please reopen the bug, see https://www.debian.org/Bugs/server-control
for details.
Regards,
Salvatore
