Description

After the upgrade at KIT, the user quotas are not reported correctly. The quota for root seems to be OK. The user quota is 0 on all OSTs, which is wrong.

e.g for root:

[root@pfs2n13 ~]# lfs quota -u root -v /lustre/pfs2wor2/client/
Disk quotas for user root (uid 0):
Filesystem kbytes quota limit grace files quota limit
grace
/lustre/pfs2wor2/client/
4332006768 0 0 - 790 0
0 -
pfs2wor2-MDT0000_UUID
2349176 - 0 - 790 - 0
-
pfs2wor2-OST0000_UUID
134219820 - 0 - - -

  pfs2wor2-OST0001_UUID
  12 - 0 - - - -
  -
  pfs2wor2-OST0002_UUID
  134219788 - 0 - - -

for a user
[root@pfs2n3 ~]# lfs quota -v -u aj9102 /lustre/pfs2wor1/client/
Disk quotas for user aj9102 (uid 3522):
Filesystem kbytes quota limit grace files quota limit

[e-mail], orentas, have you resolved this issue? do you need anything else from this ticket?

We dont think manually fixing the OST object is not a good idea. Since the filesystem have more than 100 million files.
Cu is expecting a better way to fix this issue,

I can't think of any other good ways to fix the bad IDs. I think running a script instead of repeating the commands manually would be better?
