I can't mount RAID-1 btrfs after reboot (well, sort of).
Using 2.6.31-rc5 and btrfs-progs 0.19, I created a RAID-1 fileystem
using these command line options:
# mkfs.btrfs -L btrfs-data -m raid1 -d raid1 /dev/sda4 /dev/sdb4
After which I was able to mount the filesystem with either of the below
(or both):
# mount /dev/sda4 /mnt/btrfs-sda4
# mount /dev/sdb4 /mnt/btrfs-sdb4
After a reboot, I'm no longer able to mount the filesystem from /dev/sda4:
# mount /dev/sda4 /mnt/btrfs/
Mount command complains and doesn't mount it and says I can find more
info in dmesg:
Btrfs loaded
device label btrfs-data devid 1 transid 67 /dev/sda4
btrfs: failed to read the system array on sda4
btrfs: open_ctree failed
I'm able to mount the filesystem by using /dev/sdb4:
# mount /dev/sdb4 /mnt/btrfs/
After which I can unmount it, and use /dev/sda4 to mount the filesystem:
# umount /dev/sdb4
# mount /dev/sda4 /mnt/btrfs/
Does it make sense?
It behaved like this also with some earlier kernels.
