Hi Dan,
Ah, I see. Sorry, no idea - it's been a few years since I last used ZFS,
and I've never used the Lustre ZFS backend.
Regards,
Mark

Hi Mark,
All nodes are using ZFS. OSTs, MDT, and MGT are all ZFS-based, so there's
really no way to fsck them. I could do a scrub, but that's not the same
thing. Is there a Lustre/ZFS equivalent of 'tune2fs -O [^]quota' for ZFS?
I'm guessing that at some point, a large number of files was removed and
somehow quota accounting missed this.
There should be a simple way to reconcile or regenerate what quota has
recorded vs what is actually on disk, which I have verified two different
ways.

Hi Dan,
I think it gets corrected when you umount and fsck the OST's themselves
(not lfsck). At least I recall seeing such messages when fsck'ing on 2.12.
Best,
Mark

No combination of lfsck runs has helped with this.
Again, robinhood shows 1796104 files for the group, an 'lfs find -G gid'
found 1796104 files as well.
So why is the quota command showing over 3 million inodes used?
There must be a way to force it to recount or clear all stale quota data
and have it regenerate it?
Anyone?

We have a lustre filesystem that we just upgraded to 2.15.3, however
this problem has been going on for some time.
The quota command shows this:
Disk quotas for grp somegroup (gid 9544):
Filesystem used quota limit grace files quota

The group is not using nearly that many files. We have robinhood
installed and it show this:
Using config file '/etc/robinhood.d/lustre1.conf'.

Any ideas what is wrong here?
