I've checked all data disks according to instructions. All looks good except for my disk 6 which gives the following message when I attempt a repair. I think this is a new issue after my disk 2 issues few days ago:
Not available
Phase 1 - find and verify superblock...
- reporting progress in intervals of 15 minutes
- block cache size set to 741696 entries
Phase 2 - using internal log
- zero log...
zero_log: head block 213748 tail block 213682
ERROR: The filesystem has valuable metadata changes in a log which needs to
be replayed. Mount the filesystem to replay the log, and unmount it before
re-running xfs_repair. If you are unable to mount the filesystem, then use
the -L option to destroy the log and attempt a repair.
Note that destroying the log may cause corruption -- please attempt a mount
of the filesystem before doing this.
From this I tried to mount the array but disk 6 shows un-mountable
From this I understand I can either do a xfs_repair -L but stand a chance to loose data or try to move data off the disk, re-format it and put it back into the array but what about the parity, will it rebuild or will it update as I move data of the disk. besides I think I cannot move data if I cannot mount the disk. Can I use MC when unmounted and move data between disks? I'm a bit unclear on that. Attached is the diagnostics as current
