Can (and how) I re-enable my disk after unclean shutdown.

[Dieter Koblenz]

I had a power fail, and on boot of unRAID I noticed one of my four disk array's was disabled and emulated. I ran a successful smart check, and would like to re-enable the disk. How can I? 

 

It's an xfs system, so per help files I started the array in maintenance mode and ran check on the disk involved. I got this result, but I'm clueless on what to do next.

 

Phase 1 - find and verify superblock...
Phase 2 - using internal log
        - zero log...
        - scan filesystem freespace and inode maps...
        - found root inode chunk
Phase 3 - for each AG...
        - scan (but don't clear) agi unlinked lists...
        - process known inodes and perform inode discovery...
        - agno = 0
        - agno = 1
        - agno = 2
        - agno = 3
        - process newly discovered inodes...
Phase 4 - check for duplicate blocks...
        - setting up duplicate extent list...
        - check for inodes claiming duplicate blocks...
        - agno = 0
        - agno = 3
        - agno = 1
        - agno = 2
No modify flag set, skipping phase 5
Phase 6 - check inode connectivity...
        - traversing filesystem ...
        - traversal finished ...
        - moving disconnected inodes to lost+found ...
Phase 7 - verify link counts...
No modify flag set, skipping filesystem flush and exiting.Phase 1 - find and verify superblock...

And here's a diagnostics report.

Handling of failed/disabled disks is covered here in the online documentation accessible via the ‘Manual’ link at the bottom of the UnRaid GUI.

Thank you, I managed to restore the disabled disk.
