Hi Phill,

However it has just become apparent that the new servers are not enforcing quotas, though they are set for all users on two of our volumes. This has lead to the situation where one of our volumes is almost full, and is negatively affecting performance.

Looking at the documentation for lfs suotaon / quotaoff it suggests that they are depreciated since lustre version 2.4.x. We are currently running 2.9.0 on Centos 7.

How can I check to see if quota enforcement is turned on, and if not turn it on once we have people back under quota again (or adjusted their quota).

You may have a look here for enabling disk quotas:
http://doc.lustre.org/lustre_manual.xhtml#enabling_disk_quotas

To verify that quota enforcement is configured, run the command 'lctl get_param osd-*.*.quota_slave.info'on the MDS (see section 24.2.2.1. Quota Verification).

Cheers,
Guido
