I think things started after the latest update of OMV that is running on Armbian/Odroid HC4. dmesg shows lots of SATA problems:

I then noticed that the partition is mounted read-only. I unmounted the file system and tried a btrfs check:
root@nas:/home/siegbert# btrfs check -p /dev/sdb1
Opening filesystem to check...
parent transid verify failed on 8604712763392 wanted 112885 found 109597
parent transid verify failed on 8604712763392 wanted 112885 found 109597
parent transid verify failed on 8604712763392 wanted 112885 found 109597
Ignoring transid failure
leaf parent key incorrect 8604712763392
ERROR: failed to read block groups: Operation not permitted
ERROR: cannot open file system
Mount read-only fails now:
root@nas:/home/siegbert# mount -t btrfs -o ro /dev/sdb1 /mnt/tmp/
mount: /mnt/tmp: wrong fs type, bad option, bad superblock on /dev/sdb1, missing codepage or helper program, or other error.
That's what dmesg says after this attempt:
[71070.589557] BTRFS info (device sdb1): using crc32c (crc32c-generic) checksum algorithm
[71070.589603] BTRFS warning (device sdb1): 'recovery' is deprecated, use 'rescue=usebackuproot' instead

I am stuck. What to do now with this file system?
