Hello, i played a little bit with btrfs and raid levels, but now i stuck on recovering if the first disc is missing.
First i tried removing the second disc -> works! # mkfs.btrfs -m raid1 -d raid1 /dev/sdb /dev/sdc # mount /dev/sdb /mnt - copy some data - shutdown, remove /dev/sdb, add a empty /dev/sdb, reboot # btrfs device scan # mount -o degraded /dev/sdb # btrfs device add /dev/sdc # umount /mnt # mount /dev/sdb /mnt -> EVERYTHING OK AGAIN But now i removed the first (sdb) device. And the steps above dont work anymore. If i try to: # btrfs device scan (found my raid array) # mount -o degraded /dev/sdb mount asked to specify the filesystem type, this was expected because sbd is empty. Now try with sdc # mount -o degraded /dev/sdc and i got a bad superblock message. What should i do now? Thanks!
