Description
Customer provided the following feedback, concerning the information provided in the current Lustre Operating Manual about how to set up quotas:
"My questions had to do with several issues.
(1) The manual lays out different approaches based on whether or not your lustre version is 2.4 or higher, but doesn’t explain how to verify what lustre version you’re using.
(2). The manual doesn’t make clear what server you’re supposed to run the various commands on. The section on enabling disk quotas, mentions the MGS server earlier in the section, but not lower down where it instructs you to issue the commands “lctl con_param testfs1.quota.ost=ug, and lcdl con_param testfs2.quota.mdt=g” I assumed this needed to be done on the MGS, and that seemed to work.
(3) At the end of the section on enabling disk quotas, the manual suggests you issue the command “lcdl get_param osd-..quota_slave.info”. I did this before enabling quotas to verify they were off, and it worked. I tried it again, on the MGS server, after enabling quotas, and got nothing but an error.
(4) In the section on Quota Administration, the manual makes no mention whatsoever of what server these commands should be run on. It took some thought and experimenting on my part to discover they need to be run from a lustre client, not a lustre server (correct me if I’m wrong).
At this point, I THINK the quotas are enabled and working properly, but I’m worried that the command I mention in (3) above is returning an error."
