Upgrade from 6.11.5 to 6.12 results in "Unmountable: Unsupported or no file system" of cache drive

I started this topic yesterday already, but unfortunately it seems like it never went online.

After upgrade from 6.11.5 to 6.12 my array did not start by itself. After manual start the disk where shown, but the cache disk says "Unmountable: Unsupported or no file system" (btfrs) on the main page. Dashboard says "active" and "healthy".

I rebooted without any luck. Stopping and restarting he array resulted in having the array disks "unmountable" as well, but shares where shown. Rebooting the system then lead the array to be mounted, but the cache drive still not.


Any quick fix for this?


EDIT: I was using firefox, but tried reboot and restarting the array with chrome now as well. Filesystem check for the cache drive when having the array mounted in maintenance mode is:


[1/7] checking root items
[2/7] checking extents
[3/7] checking free space tree
[4/7] checking fs roots
[5/7] checking only csums items (without verifying data)
[6/7] checking root refs
[7/7] checking quota groups skipped (not enabled on this FS)
