[lustre-discuss] Quota values showing as inaccurate

[Scott Wood]

Hi All,

We've recently drained and removed 72 OSTs as per 14.9.3. Removing an OST from the File System.  Since doing so, our quotas are showing as inaccurate.  We don't enforce, but we do use them for monitoring use so we'd like to get them happy again.  We have a scheduled maintenance window coming up and I'm curious if there are any steps we should take during the downtime to help the system reconcile the quota values.

We're ldiskfs on lustre 2.15.5.  Depending on how busy the outage is, we may upgrade to 2.15.7 but we may not be able to fit it in.

Example:

[root at lustreclient ~]# lfs quota -u somedude /mnt/lustre/
Disk quotas for usr somedude (uid 10012):
     Filesystem  kbytes   quota   limit   grace   files   quota   limit   grace
   /mnt/lustre/ [5024896]       0       0       - 6812714       0       0       -
uid 10012 is using default block quota setting
uid 10012 is using default file quota setting
Some errors happened when getting quota info. Some devices may be not working or deactivated. The data in "[]" is inaccurate.

Cheers
Scott
