2017-01-04 19:42:08 MichaelE description Converted a lvm partition from ext4 to btrfs, then deleted ext subvolume and started btrfs balance. Balance job crahsed after some time leaving the partion in ro status. btrfs check on unmounted partition did not work. Could remount with -o recovery which also started balance job again. Can somebody tell me what cause the crash and whether any data got lost? I'll attach the part of the kern.log as well.
