I then mounted it and rsynced several TB of data onto it. mkfs.btrfs -m raid1 -d raid1 /dev/sdf /dev/sdg The command btrfs fi df /mnt/btrfs result in the following output: Data, RAID1: total=2.64TiB, used=2.22TiB Data, single: total=8.00MiB, used=0.00 System, RAID1: total=8.00MiB, used=380.00KiB System, single: total=4.00MiB, used=0.00 Metadata, RAID1: total=4.00GiB, used=2.94GiB Metadata, single: total=8.00MiB, used=0.00 I am a bit confused because of the "single"-entries. They are not shown in the UseCases-example on the btrfs-website and I wonder if I did something wrong. I also would like to know if its possible to label a multi-disk filesystem after creation. For your information, I am using Btrfs v3.12+20131125 and kernel 3.11.10-7 64bit. My distribution is an openSUSE 13.1. Yours Stefan
