what is the syntax to use to specify xfs in ceph.conf

what is the syntax to use to specify xfs in ceph.conf

[Isaac Otsiabah]

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" ?

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.
