  • 6.5.1-rc5 - Drives showing "no file system" and then fine

      • Solved Annoyance

    I moved a drive out of my main rig because it's read speeds were getting wonky but otherwise it was stable. When I added the drive to my backup unraid server, it showed up as unformatted. When I did a new config and put the drive in a different order, the drive that was moved showed having data but another drive showed as unformatted. Adding both of these drives by themselves showed data. This was under Safe Mode, no GUI. Memory test with a recent MemTest86 build completed a pass with no errors.

     

    After adding the 6TB as Disk 8. This system has no Parity drives.

    I reverse the drive assignment, Disk 1 is now Disk 8, Disk 2 is now Disk 7, and so on. A different drive showed up as not having a file system.unformatted2.thumb.png.8cf83e774fc860f474ac72c0d9369935.png

    Both disks have the same UUID:

      

    Apr 11 21:47:50 NASBackup kernel: XFS (md8): Filesystem has duplicate UUID 6e5537c6-38fe-4f06-8d46-587f6c2185fe - can't mount

     

    Likely one was rebuilt for the other at some point in the past, so it will only mount the first one, you can change the UUID in either one:

      

    xfs_admin -U generate /dev/sdX1

    Note the 1 in the end.

    Now there's a long set of odds there. The existing 6TB drive was replaced because it started to get errors and the drive I replaced it with must of been the one that's now giving wonky read speeds. I ran that xfs_admin command and everything mounted up correctly.

     

    Logic to detect this in the GUI might help prevent against un-needed panic.
