When my ceph data drives use btrfs as the underneath fileystem, the devices in my ceph.conf contain the lines "btrfs devs = /dev/sdx" as shown below. ceph.conf ======= ....... ....... ....... ...... [osd.0] host = host1 public address = 10.5.0.123 cluster address = 10.5.1.123 btrfs devs = /dev/sde [osd.1] host = host2 public address = 10.5.0.123 cluster address = 10.5.1.123 btrfs devs = /dev/sdf ....... ....... ...... Now, i want to use xfs as the underneath filesystem so in the ceph.conf file, should the lines "btrfs devs = /dev/sdx" be changed to "xfs devs = /dev/sdx" ?
