It's definitely not _easy_ to do this, but possible. I don't think this was ever tested, but roughly: - change the filesystem label via e2label on each OST/MDT - binary edit the "last_rcvd" file on each OST/MDT - UUID at offset 0 - binary edit the "CONFIGS/mountdata" file - two UUIDs in there, IIRC - regenerate the mount configuration via "writeconf" (procedure in manual) I don't _think_ the UUIDs or filesystem name are stored elsewhere, but like I said, this has never been tested so should probably do this on a test filesystem first and verify it can be mounted properly afterward.
