[Lustre-discuss] Quota not functioning on all OSTs

[Michael Losapio]

Hey folks,

I have a bit of an anomaly...

Lustre quotas are only working on a portion of my OSTs despite having
the correct parameters set...

[root at balki ~]# lfs quota -u mjl19 -v /scratch
Disk quotas for user mjl19 (uid 1552540):

[root at oss2 ~]# tunefs.lustre --dryrun --param /dev/mapper/ost_scratch_29

   Read previous values:

Mount type: ldiskfs
Flags:      0x1002
              (OST no_primnode )

failover.node=10.0.1.236 at o2ib failover.node=10.0.1.235 at o2ib
ost.quota_type=ug

I even tried to reset the user quota (thinking that perhaps this OSS
was offline during the initial setting)... no change and this isn't an
anomaly for the user but for all users on those OSTs

Does this mean I have to run a lfs quotacheck across the entire
filesystem? If yes, how dangerous is it to do on a live system?

Thanks,

Mike
