[6.12.6] mixed array btrfs format unmountable

Hi,

after OS update (6.11.0 to 6.12.6) the mixed array wiht btrfs and xfs disk is not complete running, only xfs is running.

I ask first in the german section (https://forums.unraid.net/topic/150298-6126-btrfs-format-unmountable/), and my solution now is change both disks also to xfs.

but here is the diagnostics file:keks-diagnostics-20231230-1424.zip
