Just for fun, I tried btrfs check --repair, but no dice: [root@archiso ~]# btrfs check --repair /dev/mapper/rootvol_1 enabling repair mode warning, device 2 is missing warning devid 2 not found already bad key ordering 49 50 repair mode will force to clear out log tree, Are you sure?

I have no idea what might be the cause.
