[Lustre-discuss] Lustre-2.1, CentOS-6.2: unknown param quota_type=ug

[Johann Lombardi]

In lustre 2.x, this must be mdd.quota_type (instead of mdt.quota_type). A patch was landed to master some time ago (will be available in 2.2) to interpret mdt.quota_type as mdd.quota_type transparently, see http://review.whamcloud.com/#change,354.

Cheers,
Johann

I decided to defer quota setup until later because I had a note to this effect from a much earlier install. So, I got everything up and running without quota, MGS MDS on same node but different LUNs, 4 OSS with external journals, client.
