[Ocfs2-users] Quota errors

[Nicolas Ecarnot]

Hi,

On our 2-nodes cluster (ubuntu server 12.04 LTS, 64bits 3.2.0-24-generic 
kernel, ocfs2 1.6.3-4ubuntu1 package), things seem to run nicely.
But /var/log/kern.log on both nodes is constantly showing the errors below :

When I've formatted this partition (mkfs.ocfs2), I've activated the 
usrquota and grpquota features.
But I've never used them. In my /etc/fstab, I haven't added the usrquota 
nor the grpquota options.
Though tunefs.ocfs2 -Q blahblah is telling me the quota features are 
well available, I thought the problem was due to this (quota in tunefs 
and not in fstab).

When I saw all these errors, I unmounted the partitions, I added the usr 
and grp quota options in fstab, and re-mounted it.
Nothing changed, nothing improved, the errors are still there.

Googling around lead me to try things like quotaoff, checkquota and so 
on, but was useless.

I must add that a couple of months ago I unmounted everything and 
successfully passed a planned ocfs2.fsck on this partition.

Are these errors severe?
What must I do to get rid of them?
