I'm creating a btrfs using
sudo mkfs.btrfs -m raid1 -d raid1 <small-disk> <large-disk> or sudo mkfs.btrfs -m raid1 -d raid1 <large-disk> <small-disk>
it creates the fs with the size of the sum of the two disks/partitions, but
btrfs fi df <mountpoint>
gives me RAID1 for data, system and metadata
How can this be correct?
Is there some way like mdadm's
to see what btrfs is doing and to assure myself my raid1 is secure? It's not terribly important data, hence it's ok to use btrfs, but i don't want to lose it either.
