[LU-7846] Impose subdirectory mount via nodemap

Related — Fri, 10 Mar 2017 16:08:27 +0000

We would like to be able to impose a subdirectory mount for some clients. The idea is that for clients which NID is among a given range, we only let them mount a predefined subdirectory on Lustre.
Given that we already have the Nodemap concept that is a policy group consisting of one or more NID ranges, we would like to extend this concept by adding a fileset information to it. So from every client pertaining to a nodemap on which a fileset information has been set, we can only mount the subdirectory corresponding to the fileset defined.

The objective of this ticket is to share a proposal on how Nodemap can be enriched with a fileset information.
I will post a patch with my initial proposal.

Thanks,
Sebastien.
