I assume you are running ldiskfs as the backend?  If so, have you tried regenerating the quota info for the OST?  I believe the command is “tune2fs -O ^quota <ost_block_device>” to clear quotas and then “tune2fs -O quota <ost_block_device>” to reenable/regenerate them.  I don’t know if that would work, but it might be worth a shot.

Just to clarify, the "tune2fs -O ^quota; tune2fs -O quota" trick is not really the best way to do this, even though this is widely circulated.

It would be better to run a full e2fsck, since that not only rebuilds the quota tables, but also ensures that the values going into the quota tables are correct.  Since the time taken by "tune2fs -O quota" is almost the same as running e2fsck, it is better to do it the right way.

Cheers, Andreas
