I came to the same conclusion and decided my time was better spent getting the data moved from backup to the array rather than guess what had happened. Disk 4 was pulled due to write errors and before I could rebuild it, I noticed my shares not mounting while it was being emulated and thus my original ask. I appreciate the time, and thanks!

Here you go. Checked the files on Disk 5 that are in the share and they all appear corrupted/unplayable/unreadable/etc compared to my backups. nyarlathotep-diagnostics-20240110-1631.zip

After a long time (I edited a lot of . out for brevity).

I have backups of all the data and replacement drives (Drive 4 is currently emulated). Is it best to just format these and restore from backup?

I ran it from the CLI. It ran overnight and came back with no superblocks found. Drive 4 is still unmountable and all the files on drive 5 appear corrupted, or at least every PDF, doc, mp4, etc file I tried opening wouldn't work.

Missed the 'run from the GUI part, but both drives exit out with "Sorry, could not find valid secondary superblock" Looks like I may have to restore from backups?

I ran xfs-repair -n from the GUI and then then from the CLI. I restarted the array, and the shares are back and populated. But no it says I have an unmountable disk on md4p1 and offers to format. Unfortunately, the files on another of the disks while present appear to be all corrupted as none of them will open in their respective apps compared to the backups I have. Gets more and more interesting. Logs say now to run xfs_repair on md5p1. As for mounting the original disk, it is currently pulled from the array and I was going to check it with TestDisk to see if it can find anything. When it was in the system it reused to mount from unassigned devices.

I have an UNRaid server where shortly after rebuilding a failing drive another drive has failed. I stopped the array, removed the device and restarted and noticed my shares now have no files. The dockers can still pull files, but the share is blank. All of the files that where on this drive (and the array in general) are backed up elsewhere. I have checked the logs, and see it recommends I run xfs_repair on the emulated drive md4p1. I have done this with -n, -v, and -vL and it cannot find any superblocks and just terminates with no other information. Is there a way to repair the emulated drive to restore my share files so I can see what I need to restore from lost&found from my backups, or do I have to create a new configuration? Any help or direction would be appreciated. nyarlathotep-diagnostics-20240108-1936.zip
