You can't achieve that with raid1 which requires minimum two devices. >> >> -dconvert=single -mconvert=dup -sconvert=dup > > Actually, I'm reminded with multiple devices that dup might not be possible. Instead you might have to using single for all of them. Then remove the device you want removed. And then do another conversion for just -mconvert=dup -sconvert=dup, and do not specify -dconvert. That way the single metadata profile is converted to duplicate. I think it didn't work. btrfs balance start -dconvert=single -mconvert=single -sconvert=single --force /mnt/BTRFS/Video/ After >10h: btrfs balance status /mnt/BTRFS/Video/ No balance found on '/mnt/BTRFS/Video/' root@homeserver:~# btrfs fi df /mnt/BTRFS/Video/ Data, RAID0: total=4.00GB, used=4.00GB Data: total=2.29TB, used=2.29TB System: total=32.00MB, used=256.00KB Metadata: total=4.00GB, used=2.57GB root@homeserver:~# btrfs fi show Label: none uuid: 989306aa-d291-4752-8477-0baf94f8c42f Total devices 2 FS bytes used 2.29TB devid 2 size 2.73TB used 1.15TB path /dev/sdc1 devid 1 size 2.73TB used 1.15TB path /dev/sdb1 (you see that I cleaned up beforehand, so that enough space is available, generally).
