[LU-5070] Utility to change filesystem name

• Type: New Feature
• Resolution: Fixed
• Priority: Major
• Fix Version/s: Lustre 2.9.0
• Labels: medium
• Assignee: nasf (Inactive)
• Reporter: Andreas Dilger

Description

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

Issue Links

• is related to: LU-18436 need simple process to rebuild CONFIGS/mountdata file
• is related to: LU-8900 Lustre snapshot based on ZFS backend
