[root@OVS2-253-32 ~]# service o2cb online
Starting O2CB cluster ocfs2: OK
[root@OVS2-253-32 ~]# service o2cb start
Starting O2CB cluster ocfs2: OK
[root@OVS2-253-32 ~]#
but see :
     During adding servers ([192.168.20.253]) to server pool (jojo), Cluster setup failed: (OVM-1011 OVM Manager communication with 192.168.20.254 for operation HA Setup for Oracle VM Agent 2.2.0 failed: errcode=50006, errmsg=Do 'clusterm_init_root_sr' on servers ('192.168.20.253') failed. )
Select     Server Host/IP     Server Name     Server Type     Status     Server Location     Server Pool Name     Logs

but edit this server work fine. i use doc in step by step configure and no error occur in configuration but still see this error on adding new server and HA can't works correctly (only when i power off virtual quest machine after 15 second this server goes up and live migration not work correctly )when i shutting down one virtual machine server guest still wait for powering up this server
ocfs2 kernel module load correctly
cat /var/log/ovs-agent/ovs_root.log
