re-enabling quota enforcement => invalid argument

[Jan Schulze <schulze@xxxxxxxxxxxxxxxxxxxxxxxxxxx>]

Hi all,

I have an XFS filesystem with pquota accounting and enforcement. It was working 
well, but recently I had to disable enforcement for a short time. Now I want to 
switch it back on, but I get the error "XFS_QUOTAON: Invalid argument".

Does anyone know, what to do? Any suggestions are welcome. Thanks in advance.

[root@coffein raid]# xfs_quota -x -c "state -a" /raid
User quota state on /raid (/dev/sdb1)
