I run Debian Jessie with a kernel upgrade to 4.0.0 from the Debian experimental repository. My BTRFS-Tools remain at 3.17.-1 I wanted to convert a RAID0 array on /dev/sdb3 and /dev sdc3 from RAID0 to RAID1 so I ran the commands: mount /dev/sdb3 /mnt btrfs device add -f /dev/sdc3 /mnt btrfs balance start -dconvert=raid1 -mconvert=raid1 /mnt All appeared well with output similar to "395 of 395 chunks converted" but I think nothing happened. The array contains a subvolume @export with size (per "du -sh @export") of 442G. The pertinent output from "btrfs filesystem show" reports: Label: none uuid: 647eb0f8-7732-40bc-a4a4-0d1b31a8ae16 Total devices 2 FS bytes used 443.05GiB devid 1 size 1.36TiB used 223.03GiB path /dev/sdb3 devid 2 size 1.36TiB used 223.03GiB path /dev/sdc3 My array remains RAID0 if I understand the above output correctly. This output persist through a reboot and no data was lost.
