[LU-5070] Utility to change filesystem name

Duplicate — Fri, 7 Jul 2017 21:15:53 +0000

It would be useful to have a utility to modify the name of an existing filesystem, though the filesystem would likely have to be unmounted from the clients/servers at the time.

This would require changes to:

change labels of the backing filesystems (MDT/OST)
change fsname and svname in mountdata (ldiskfs, or setting the equivalent ZFS dataset properties
rename the config log for this filesystem in /CONFIGS/ {fsname}
-config, rewrite contents with new MDT/OST names on MGS, MDT, OST
