[[email protected] storage_cluster]$ sudo ceph-deploy new ceph-node [[email protected] storage_cluster]$ sudo ceph-deploy install ceph-node [[email protected] storage_cluster]$ sudo ceph-deploy mon create-initial [[email protected] storage_cluster]$ sudo ceph-deploy admin ceph-node [[email protected] storage_cluster]$ sudo ceph-deploy mgr create ceph-node
Now add my testing 20GB disk from my xen server additional disk.

Now show your server all disk using below command.
[[email protected] storage_cluster]$ sudo lsblk [[email protected] storage_cluster]$ sudo lshw -class disk [[email protected] storage_cluster]$ sudo sfdisk -l -uM
Step #04: When ready your disk then deploy ceph cluster.
[[email protected] storage_cluster]$ udo ceph-deploy disk list ceph-node [[email protected] storage_cluster]$ sudo ceph-deploy disk zap ceph-node /dev/xvdb
Then create osd using your same disk and ceph host name.
[[email protected] storage_cluster]$ sudo ceph-deploy osd create --data /dev/xvdb ceph-node [[email protected] storage_cluster]$ sudo ceph -s
