For example with two nodes:
cat /etc/ocfs2/cluster.conf
cluster:
node_count = 2
name = ocfs2
node:
number = 1
cluster = ocfs2
ip_port = 7100
ip_address = 192.168.0.2
name = host1
node:
number = 2
cluster = ocfs2
ip_port = 7100
ip_address = 192.168.0.3
name = host2
At the same time, in the file /etc/default/o2cb, the value of O2CB_BOOTCLUSTER
muster be same with the value of the cluster in cluster.conf file.
The default is ocfs2, you can change it with other string value.
The cluster.conf muster be same on every node which will mount the same LUNs.
On every node, execute the commands as below after cluster.conf copied. Yeah,
you can change the o2cb service started status at host booting time.
service o2cb onload
service o2cb online
Then you can mount the LUNS on every node.
But at first, the node must have the permissions to access the LUN, write
permission for disk heartbeat of OCFS2.

Thanks Guozhonghua! Would you mind providing a sample config?

You can setup one cluster with two nodes and using two LUNS at the same time.
I means mount different LUN with different point on the every node, and the two
nodes are in one same cluster.
Configur the /etc/ocfs2/cluster.conf

主题: [Ocfs2-users] Multiple Filesystems per Node
Hi all,
We're looking to have 2 separate iSCSI LUNs serve up two separate OCFS2
filesystems to the same set of nodes. IE, LUN 1 will mount to /mnt1 o all
nodes, and LUN 2 will mount to /mnt2.
We're having a hard time figuring out the best way to accomplish this. Is it
possible to have multiple clusters per node? Multiple FS per cluster?
Thanks!
