Hello, I'm experiencing problems while balancing a filesystem to
raid1. The versions I'm using are:
kernel-4.0.0-0.rc5.git1.3.fc22.x86_64
btrfs-progs-3.19.1-1.fc22.x86_64
The filesystem was created with one device, and I have added two more
devices afterwards. To convert it to raid1, I have used:
# btrfs balance start -dconvert=raid1 -mconvert=raid1 /mnt/btrfs_raid1
The balance process has finished, but if I check my filesystem, it
shows up as single
# btrfs fi show /mnt/btrfs_raid1
Label: 'btrfs_raid1' uuid: cd7d4b6d-fa6b-4e2e-8b53-116d25ccdf4e
Total devices 3 FS bytes used 1.19TiB
