Hallo, linux-btrfs,
please delete the option "-L" (for labelling) in "mkfs.btrfs", in some
configurations it doesn't work as expected.
My usual way:
mkfs.btrfs -d raid0 -m raid1 /dev/sdb /dev/sdc /dev/sdd ...
One call for some devices.
Wenn I add the option "-L mylabel" then each device gets the same label,
and therefore some other programs can't find the (one) device with the
defined label.
Especially
blkid
findfs LABEL=mylabel
don't work.
file -s /dev/sdb (etc.)
shows the label (and the problem).
Other tries:
mkfs.btrfs -L mylabel /dev/sdb
creates a new btrfs filesystem and overwrites prior tries.
What works:
btrfs filesystem label /dev/sdb mylabel
Viele Gruesse!
Helmut
