Adding a new node in a running cluster

sábado, 19 de maio de 2012

1- Add the new node in the file /etc/cmcluster/cmclnodelist.
2- Get the most up-to-date ASCII configuration file.
# cmgetconf -v -c clustername /etc/cmcluster/cluster.ascii

3- Query all nodes, including the new node, in the cluster.
# cmquerycl -v -c cluster_name -n node1 -n node2 cluster.ascii

4- Compare the ASCII files obtained from cmgetconf and cmquerycl.
5- Update the ASCII configuration file obtained from cmquerycl.
6- Check the new ASCII configuration file.
# cmcheckconf -v -C cluster.ascii

7- Compile and distribute the new binary cluster configuration file.
# cmapplyconf -v -C cluster.ascii

8- Start cluster services on the new node.
# cmrunnode -v newNode

9- Check the cluster status and the log file for validate.

# cmviewcl
