• Removing a cache pool device can fail to delete missing device

    • Solved Minor

    This happened recently to a user and I just confirmed it's a bug, starting on v6.7.0 when for example removing a device from a 2 device raid1 pool, the command changed from:

     

    balance start -f -dconvert=single -mconvert=single /mnt/cache && /sbin/btrfs device delete /dev/sde1 /mnt/cache &

     

    to

     

    balance start -f -dconvert=single /mnt/cache && /sbin/btrfs device delete /dev/sde1 /mnt/cache &

     

    The metadata isn't being convert to single profile, so the device delete will fail, and Unraid will keep trying every array start.

    Didn't know this was a bug and didn't have anything valuable on the disk so did the lowtech cp method just to get things done.
