Hi Yang bin,
     Not sure if you followed the right docs. I suspect you didn’t, because you should use ceph-disk and specified a FS-Type in the command.

I think you might mislead by the  quick start(http://ceph.com/docs/master/start/quick-ceph-deploy/#create-a-cluster),
 it use a directory instead of a disk as OSD(“Add two OSDs. For fast setup, this quick start uses a directory rather than an entire disk per Ceph OSD Daemon. See
ceph-deploy osd for details on using separate disks/partitions for OSDs and journals.”)

So, just read
http://docs.ceph.com/docs/master/rados/deployment/ceph-deploy-osd/ or
http://ceph.com/docs/master/install/manual-deployment/#adding-osds may help your case.

Hi 

You logs does not provides much information , if you are following any other documentation for Ceph , i would recommend you to follow official Ceph docs.
