Btrfs Problem
Hallo Zusammen,
ich habe das Problem, dass mein btrfs auf einem Raid1 unter Ubuntu 20.04 nicht mehr zu mounten ist. Der mount Befehl meldet in einem Live System " can't read superblock on /dev/md2"
Lasse ich den SUprtblock wiederherstellen, kommt die Meldung dass diese OK sind.
dmesg gibt mir folgendes aus:

Hi
nun der Superblock ist ja auch nicht das Problem....
Da steht doch dein Problem....
Nicht Vergessen Backup vor dem Fixen für den Fall der Fälle ;)
