If using mkcephfs, you can just give it a "devs" option.
I"m pretty sure this changed in bobtail (0.56). I just setup a
cluster on 0.56.1, and used the following. Worked like a charm:
[osd]
osd mkfs type = xfs
osd mkfs options xfs = "-f"
osd mount options xfs = "rw,noatime,inode64,logbufs=8,logbsize=256k"
[osd.0]
host = ceph1
devs = /dev/sdc
osd journal = /dev/sda5
[osd.1]
host = ceph1
devs = /dev/sdd
osd journal = /dev/sda6
A generic example is in the docs, here:
http://ceph.com/docs/master/rados/configuration/ceph-conf/#example-ceph-conf
Remember to use --mkfs when using mkcephfs.
HTH.
