XFS Quota Check OOM

XFS Quota Check OOM

[Stefan Priebe - Profihost AG]

Hi,

on one of our systems i want to activate prjquota support. The relevant 
disk is the root disk so i added prjquota to rootflags kernel line.

But when i do so i always get OOM out of Memory while checking quota's. 
I also upgraded the system from 8GB to 16GB RAM but still the same. 
Kernel is vanilla 2.6.32.19.

Stefan

What is the size of the filesystem, output of xfs_info, output of uname
-a, version of xfs_utils?
What are the main tasks of the system, memory wise?

This is really very very weird. Why on earth would you use such a big
root filesystem? It is extremely impractical and dangerous to store
data on the root filesystem. Do you have any good reason not to have a
small root filesystem and a distinct data one?

Oh we don't do this today. But it is a really old system where someone 
someday decided to do that. Sadly i can't change this...

Did you upgrade the kernel recently? Or simply enabled quotas?

Hi!

After booting the System to a RAM Image with prjquota (the quota check 
wents fine) and upgrading to xfsprogs 3.1.3.

I'm getting this when trying to setup a project Quota:
xfs_quota -x -c "project -s 2" /
Setting up project 2 (path /serverbackup/abc)...
Processed 1 (/etc/projects and cmdline) paths for project 2 with 
recursion depth infinite (-1).

  cat /etc/projects
2:/serverbackup/abc

cat /etc/projid
abc:2

ls -la /serverbackup/abc/
total 102412
drwxr-xr-x  2 root root        16 Aug 24 00:41 .
drwxr-xr-x 62 root root      8192 Aug 31 13:05 ..
-rw-r--r--  1 root root 104857600 Aug 24 00:41 abc

  mount
/dev/sda3 on / type xfs (rw,noatime,nodiratime,nobarrier,prjquota)

That's normal, I think. Adding project quota involves descending the
directory heirachy specified and adding the project id to every file
and directory. You can limit the recursion depth it runs to if you
want to, but the default (infinite) is to walk the entire heirarchy.

You can confirm by running a quota report and checking the output...

Cheers,

Dave.

quota report returns nothing... :-( except two newlines...

# xfs_quota -x -c "report -phnN" /

Can you post your kernel log with the OOM messages and if existing
any messages from XFS before that?
