Even if he's not aware of it, things can happen like people using rsync and preserving ownership. The original owner's usage then goes up.

Hi all,
One of my users is reporting a massive size difference between the
figures reported by du and quota.
doing a du -hs on his directory reports :
du -hs .
529G .
doing a lfs quota -u username /storage reports
Filesystem kbytes quota limit grace files quota limit grace
/storage 621775192 640000000 640010000 - 601284 1000000 1100000

Though this user does have a lot of files :
find . -type f | wc -l
581519
So I suspect that it is the typical thing that quota is reporting used
blocks whilst du is reporting used bytes, which can of course be wildly
different due to filesystem overhead and wasted unused space at the end
of files where a block is allocated but only partially used.
Is this likely to be the case ?
I'm also not entirely sure what versions of lustre the client machines
and MDS / OSS servers are running, as I didn't initially set the system up.
Cheers.
Phill.
