On the server that is running the service, check that the XFS file system is mounted.
[root@active ~]# mount | grep xfs1
/dev/mapper/VGMD1-VGMD1-LVMD1 on /mnt/xfs1 type xfs
(rw,noatime,allocsize=1g,nobarrier,inode64,logbsize=262144,wsync)
On the server that is running the service, check that the resource IP is assigned. The interface to
the public network should have two IP addresses - the statically assigned address and the floating
service IP address. For example,
[root@active ~]# ip addr show ib0
9: ib0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 65520 qdisc pfifo_fast qlen

In order to stop the cluster, execute the following commands on both servers:
# clusvcadm –d HA1
# service clvmd stop
# service rgmanager stop
# fence_tool leave
# cman_tool leave remove
# service modclusterd stop
# service cman stop
2. Update the Selinux policy. This is needed to allow a cluster server to fence the other cluster
member and take ownership of the cluster service.
