Possibly...

That sounds like a pretty old version of gfs2_quota.

One of the problems with CentOS is that it doesn't have our more recent
fixes. If you used Fedora or another more uptodate distro then this
problem should have long since been fixed. Also with the latest Fedora
(Abhi should be able to confirm the exact version) then the standard
system quota tools are available to use with GFS2.

The plan is to get rid of gfs2_quota (probably fairly shortly in Fedora,
but it will stay much longer in RHEL - until the end of the release, of
course) and use exclusively the system quota-tools package,
