November 26, 20187 yr Community Expert You have metadata corruption on disk1, see below to try and recover the data before reformatting: https://forums.unraid.net/topic/46802-faq-for-unraid-v6/?do=findComment&comment=543490
November 26, 20187 yr Author Thanks.. can the restore be back to the Array or to other drive? Any incite as to why this happen? System stalls and only option to to reboot. (This is not the first time this has happen but the worst) and before reboot I have let the system sit over night.

Likely the result of an unclean shutdown, if using btrfs you should use DUP metadata, this is the default with btrfs, just not with Unraid, but it should be, though I can't say for sure it would help in this case, but if you intend to continue using btrfs convert all disks to DUP metadata: btrfs balance start -mconvert=dup /mnt/diskX
