Configuring Shared Storage Using OCFS
If you are using Oracle Cluster File System (OCFS) for either CRS, quorum, or database files, ensure
that the new nodes can access the cluster file systems in the same way as the existing nodes.
1
Edit the /etc/fstab file on the new node and add OCFS volume information exactly as it appears
on the existing nodes:
For example:
/dev/emcpowera1 /u01 ocfs _netdev 0 0
/dev/emcpowerb1 /u02 ocfs _netdev 0 0
/dev/emcpowerc1 /u03 ocfs _netdev 0 0
2
Create OCFS mount points on the new node as they exist on the existing nodes
(for example, /u01, /u02, and /u03).
3 Run ocfstool to generate the OCFS configuration file /etc/ocfs.conf by performing the following steps:
a Ty p e startx to start the X Window System.
b Open a terminal window and type:
ocfstool
c From the menu, click Tools and click Generate Config .
d Enter the private IP address and private host name of the node and click OK .
e Click Exit .
4 Type the following commands to load the OCFS module and mount all volumes listed
in the
/etc/fstab file:
/sbin/load_ocfs
mount -a -t ocfs
Adding a New Node to the Clusterware Layer
1 Log in as oracle .
2 From the /opt/oracle/product/10.1.0/crs_1/oui/bin directory on one of the existing nodes, type
addNode.sh to start the Oracle Universal Installer.
3 In the Welcome window, click Next .
4 In the Specify Cluster Nodes for Node Addition window, enter the public and private node names
for the new node and click
Next .
If all the network and storage verification checks pass, the
Node Addition Summary window appears.
5 Click Next .
The
Cluster Node Addition Progress window displays the status of the cluster node addition process.
6 When prompted, run rootaddnode.sh on the local node.
When
rootaddnode.sh finishes running, click OK .
