Title:
XFS quotacheck OOM
Status in linux package in Ubuntu:
Won't Fix
Bug description:
Hello,
I have a 1.2 TiB XFS file system with 1.1 TiB of data and 14 million
inodes used. When I try to enable user and group quota on the file
system, XFS quotacheck is run on mount with "-o uquota,gquota". A few
seconds after the quotacheck starts, the OOM killer starts killing
processes and I get these messages on the serial console:
[ 157.508682] Out of memory: Kill process 680 (upstart-udev-br) score 1 or
sacrifice child

(mode:0x2d0)
...
Shortly before the SSH connection to the machine is lost,
/proc/slabinfo shows the following line:
slabinfo - version: 2.1
# name <active_objs> <num_objs> <objsize> <objperslab>
<pagesperslab> : tunables <limit> <batchcount> <sharedfactor> : slabdata
<active_slabs> <num_slabs> <sharedavail>
...
xfs_inode 1981333 1981333 960 17 4 : tunables 0 0 0
: slabdata 116549 116549 0
...
The machine has 2 GiB RAM, of which 1.8 GiB are used by the XFS inode
cache, if I read these numbers correctly.
The machine runs the following kernel:
# uname -a
Linux bombax 3.2.0-32-generic #51-Ubuntu SMP Wed Sep 26 21:33:09 UTC 2012
x86_64 x86_64 x86_64 GNU/Linux
#
Patches for this very issue are mentioned here:
http://oss.sgi.com/archives/xfs/2012-06/msg00362.html
(The size of the xfs_inode entry in /proc/slabcache confirms that this
is the issue, according to the person mentioning the patches.)
Can you apply these fixes to the Precise kernel?
