I had a disk in my RAID0 die: root@maru2:~# /usr/local/src/btrfs-progs/btrfs fi show 8c530f6f-7592-4d57-854d-1fae33ae7cb6 Label: none uuid: 8c530f6f-7592-4d57-854d-1fae33ae7cb6 Total devices 3 FS bytes used 329.66GiB devid 1 size 1.79TiB used 357.03GiB path /dev/sdd1 devid 3 size 931.51GiB used 178.00GiB path /dev/sdf *** Some devices missing Btrfs v3.12-43-gc2081e2-dirty So, I try to mount it with -o degraded. That fails, implying that a degraded mount needs to be read-only. So I successfully mount it read only. Then I want to add a new disk to replace the missing one: root@maru2:~# /usr/local/src/btrfs-progs/btrfs dev add /dev/sdg /mnt/ ERROR: error adding the device '/dev/sdg' - Read-only file system So I can't add a disk if it's mounted read-only, and can't mount it read-write? What am I missing?
