Bugzilla – Bug 295
quota block usage not accurate

Please see referenced log :) I'd attach it if I could, but that doesn't seem to
Basically, the block usage statistics reported by 'quota' aren't accurate until
one does a sync.
This is a feature, not a bug (no, really!) - XFS does delayed allocation
of space for buffered writes when it can, to get large contiguous extents
on disk. Since the space isn't allocated straight away, its not counted
by quota straight away - it actually cannot be counted until real space is
allocated, because we don't know until the allocation is done exactly how
much space will be needed.
