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?
