创建OSD（admin节点）
ceph磁盘相关命令参考:
http://docs.ceph.org.cn/man/8/ceph-disk/

sudo ceph-deploy disk list ceph1
sudo ceph-deploy disk list ceph2
sudo ceph-deploy disk list ceph3

准备OSD
注意prepare的盘最好使用单独的盘，单独使用分区会有点麻烦。而且不能是已经挂载的盘。
在每个节点上先解除挂载
sudo umount /dev/sdb1
在admin节点上运行

sudo ceph-deploy osd prepare ceph2:/dev/sdb
sudo ceph-deploy osd prepare ceph3:/dev/sdb
