Hi!
This fails:
# mkfs.btrfs /dev/sd[bcde]
# mount /dev/sdb /mnt/x
# btrfs device delete /dev/sdb /mnt/x
# btrfs device add /dev/sdb /mnt/x
/dev/sdb is mounted
#
It seems that I have to unmount and remount the fs using another
constituent block device before I can re-add the original block
device that the filesystem was mounted with:
# umount /mnt/x
# mount /dev/sdb /mnt/x
mount: wrong fs type, bad option, bad superblock on /dev/sdb,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
# mount /dev/sdc /mnt/x
# btrfs device add /dev/sdb /mnt/x
#
This is on up-to-date F17, kernel 3.4.0(-1.fc17) with btrfs-progs
0.19(-18.fc17).
thanks,
Lennert
