Bringing the Cluster Online
Perform the following steps to bring the cluster online.
1.
Check if the openais service is already running by entering the following command:
rcopenais status
2.
If the openais service is already running, go to step 3. If not, start OpenAIS/Corosync now by entering the
following command:
rcopenais start
3.
Repeat the steps above for each of the cluster nodes. On each of the nodes, check the cluster status with the
following command:
crm_mon
If all of the nodes are online, the output should be similar to the following:

Configuring the NFS Resource with STONITH SBD Fencing
The following subsections describe how to set up an NFS resource by installing the NFS kernel server, configuring the
shared VD by partitioning, applying the ext3 file system, and configuring the stonith_sbd fencing.
3.5.4.1
Install NFSSERVER
Use Yast to install nfs-kernel-server and all of the required dependencies.
3.5.4.2
Configure the Partition and the File System
Perform the following steps to configure the partition and the file system.
1.
Use fdisk or any other partition modification tool to create partitions on the virtual drive.
For this example, /dev/sda is on a shared virtual drive with two partitions created: sda1 (part1) for sbd and sda2
(part2) for NFS mount (the actual data sharing partition)
2.
Use mkfs to apply the ext3 file system to the partition(s)/
sles-ha1:~ # mkfs.ext3 /dev/sda1
sles-ha1:~ # mkfs.ext3 /dev/sda2
