Ah. I can reply to myself after checking the logs when I try to mount
with dmesg(1).

Two successive mount-attempts give indeed a consistent result:

[ 3712.163040] device fsid 794be0222f8f0708-ffaf918752666783 devid 1

[ 3714.221224] btrfs: failed to read tree root on dm-7
[ 3714.221461] btrfs: open_ctree failed

I then make the the assumption that my copy of btrfsck is not giving
correct output.
