btrfs is deprecated since Luminous and it will no more be tested. If btrfs is used, you have to add an extra parameter to ceph.conf to allow ceph-disk to activate btrfs OSD's. In our default config this is not the case.
From Luminous release note [1]: "We no longer test the FileStore ceph-osd backend in combination with btrfs. We recommend against using btrfs. If you are using btrfs-based OSDs and want to upgrade to luminous you will need to add the follwing to your ceph.conf: enable experimental unrecoverable data corrupting features = btrfs The code is mature and unlikely to change, but we are only continuing to test the Jewel stable branch against btrfs. We recommend moving these OSDs to FileStore with XFS or BlueStore."
