I'm not a ptools expert so I had to ask around. This turned out to be PV942815 - XFS quota reporting interacts badly with delalloc "We get a constant trickle of confused people who've found that the used space reported by repquota/quota does not get immediately updated after creating new files / extending existing ones. The problem is a result of buffered IO in XFS doing delayed allocation - if we have not done an allocation, the quota accounting has not been updated, so we end up with effectively stale data being reported. This affects CXFS too, of course. After discussion a few weeks back on the XFS conf. call, it was decided to not change CXFS (too expensive to do a flush on all nodes) but that we can make some simple XFS changes to make this less of a problem - i.e. flushing delalloc data just before we extract quota information." -Nathan Patch looks good to me.
