If blkid shows both the devices and if you are running 'btrfs dev scan'
during boot, then yes kernel should see both the devices.
Just to be sure, Can you reconfirm if the below blkid output is taken
at the time of the bootup where you are running btrfs dev scan in the
script ?
If you have a choice pls add, 'btrfs fi show -d' as well for the outputs
to be taken at the time of boot just before system's 'btrfs dev scan',
Pls do share your /etc/fstab output for /var/local/space (I guess
you don't have -o degrade option) which is good for this debugging,
which means mount fails if any one of the device is missing.
Thanks, Anand
