Hi all,

I am using a single volume across two devices sdb7 and sda1, initially
created on sdb7, and added sda1 using btrfs-vol later. The fstab entry:

/dev/disk/by-id/scsi-SATA_ST31000333AS_9TE12DSC-part7
 /mnt/btrfs btrfs defaults 1 2

Now after boot I get:
----
device fsid c4822885057410c-d2d65a83c2f15fb4 devid 1
 transid 73034 /dev/sdb7
btrfs: failed to read chunk tree on sdb7
----

So I have to run btrfsctl -a first, then mounting works. Can this be done
via fstab?

Thanks,
Thomas
