In the lfs sections 40.1.1, 40.1.3 and 40.1.4 of the Lustre manual, we reference “lfs quotacheck …” and “lfa quotaon …”, but on master, these lfs options don’t exist. ‘setquota’ and ‘quota’ are the only valid LFS options dealing with quota.

Add a condition to a text box like "Starting in Lustre 2.6, the ... commands were removed, and ... should be used instead."
