[Lustre-discuss] Per directory quota

[Christopher J.Walker]

I know Lustre can do quotas per user, but can Lustre do quotas on a per
directory basis? I can't work out how to do this from the manual.

To be more specific, the software we use[1] is written by people using
GPFS and we'd like an equivalent to the GPFS command:

	mmlsquota -j

which AIUI finds out how much space is used under a directory.

We could use

	du --summarize mydirectory

but for a directory containing a large number of files, this takes a 
long time - and is presumably not very  efficient. If there were an "lfs 
du" it would presumably be more efficient, but even so, probably still 
resource intensive.

Am I missing something?
