Hmm, stupid me - I had only some files belonging to user 'root' on that
filesystem.
Checking the quota of a user when there are no user-files does not work.
So for the record: no quota, no space accounting if there is nothing to account
for.
TLDR:
I have since reformatted, issued "lctl conf_param hebetest.quota.mdt=ug" and "lctl conf_param
hebetest.quota.ost=ug", just to see these error messages again.
For the fun of it, I did "lctl conf_param hebetest.quota.mdt=u" and "lctl conf_param
hebetest.quota.ost=u", which did not provoke these messages again.
I asked for my quota
--------------------------
lfs quota -v -u troth /lustre/testhebe
Disk quotas for usr troth :
Filesystem kbytes quota limit grace files quota limit grace
/lustre/testhebe
[0] 0 0 - 0 0 0 -
hebetest-MDT0000_UUID
0 - 0 - 0 - 0 -
quotactl ost0 failed.
quotactl ost1 failed.
Total allocated inode limit: 0, total allocated block limit: 0
Some errors happened when getting quota info. Some devices may be not working or deactivated. The data
in "[]" is inaccurate.
------------------------
"quotactl failed" never happens/is never explained?
Since measuring a zero is always tricky business, I put two directories pinned to my two OSTs and
wrote one file each _as user troth_.
Now I get
-------------------------
lfs quota -v -u troth /lustre/testhebe
Disk quotas for usr troth (uid 4128):
Filesystem kbytes quota limit grace files quota limit grace
/lustre/testhebe
1525409 0 0 - 4 0 0 -
hebetest-MDT0000_UUID
8 - 0 - 4 - 0 -
hebetest-OST0000_UUID
704780 - 0 - - - - -
hebetest-OST0001_UUID
820622 - 0 - - - - -
Total allocated inode limit: 0, total allocated block limit: 0
------------------------------------
(and of course the group quota also works).
Cheers,
Thomas

Hi all,
I have this test system where the OSS are CentOS 7.4, ZFS 0.7.1, the MDS uses ldiskfs. Lustre version
= 2.10
When I check the quota of some user - "lfs quota -u troth /lustre/hebetest" - I'm told by the client
that the data may be inaccurate, log entry is
> LustreError: 10006:0:(osc_quota.c:291:osc_quotactl()) ptlrpc_queue_wait
failed, rc: -2
while the OSS says

--quota ...
osd-*.*.quota_slave.info reads
target name: hebetest-OST000..
pool ID: 0
type: dt
quota enabled: none
conn to master: setup
space acct: ug
user uptodate: glb[0],slv[0],reint[0]
group uptodate: glb[0],slv[0],reint[0]
project uptodate: glb[0],slv[0],reint[0]
everywhere.
I have switched on quota enforcement in the meantime, so it is
quota enabled: ug
by now. As expected, no impact.
But, "Space accounting" - should just be there, once I have a ZFS backend?
rc: -2 = /* No such file or directory */ - which file is missing?
Did I manage to delete a quota file on the OSTs? How did I do that?
The "isn't functional" error message shows up in LU-9790, but that is about
project quota.
Regards,
Thomas
