Hello

I was hoping I can get help. After the upgrade to 6.3.2 My shares suddenly are missing files. I've determined that it is my one disk which I'm temporarily swopping out with another. The strage thing is the disk never showed up an error or warned my to be not working well, The total space available remains the same. In the mean time I get error messages like above and do not know what to do now. I'm attaching my diagnostics file if someone can maybe have a look and assist.

There must be something seriously wrong. I keep more or less 120 G of Photo masters on my array. They keep disappearing and are only available in Lightroom after a restart for a while. 90% of them then disappear again. I've replaced a disk I suspected had some trouble but this still happens.

You need to Check Disk File Systems on disk 2

After fixing the filesystem you'll also need to rebuild disk2 since it's currently disable.

SMART looks good and it was disabled before current diags, so check cables and rebuild to the old disk, if it gets disable again grab the diagnostics before rebooting.

You need to Check Disk File Systems on disk 2

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

Use xfs_repair -L, usually there's no data loss.
