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? What's my way around this?
