Hello!
I seem to have run into trouble with btrfs filesystem on my OpenSuse
Tumbleweed installation. The root filesystem (sdb3) which is in btrfs
is mounted readonly during boot.
The filesystem is on a WD hard drive. I did an extended check on the
drive using WD's Data Lifeguard Diagnostic tool w

I have a filesystem on top of md raid5 that got a few problems due to the
underlying block layer (bad data cable).
The filesystem mounts fine, but had a few issues
Scrub runs (I didn't let it finish, it takes a _long_ time)
But check --repair won't even run at all:
myth:~# btrfs --version

I stopped using Btrfs RAID-5 after encountering this problem two times
(once due to a failing SATA cable, once due to a random kernel problem
which caused the SATA or the block device driver to reset/crash).
As much as I can tell, the main problem is that after a de- and a
subsequent re-attach (on
