Except for disk3 all disks appear to be missing a valid filesystem, but disk3 is the only one set to xfs, all the others are set to auto, auto should work fine but try changing all the other disks to xfs, with the array stopped click on each disk and change the filesystem to xfs, then start array and if post new diags.

In any case you can run xfs_repair on each disk, it will search the disk for a backup superblock, if those are not also damaged it should recover the filesystems. https://wiki.unraid.net/Check_Disk_Filesystems#Drives_formatted_with_XFS
June 9, 20197 yr Author after running "xfs_repair" all my disks are visible, I miss 11% of the data. I miss 22 shares and have created a "lost + found" shares how to put all that in order attached new diagnostic berry-diagnostics-20190609-1559.zip
