Situation

How to move Novell Cluster Services SBD partition in OES2 Linux from device /dev/sdb to /dev/sdc for example.

Resolution

1. Down the (whole) cluster using rcnovell-ncs stop command on each node you have. This needs to be done on ALL nodes before proceeding.

2. Delete the SBD partition on /dev/sdb using nssmu. Avoid using other tools like fdisk in order to make sure this information will be replicated to the other nodes.

3. use "sbdutil" to create a new SBD partition on /dev/sdc.
Example:
Usage sbdutil -c -d device [-s] [-n clusterName]
sbdutil -c -d /dev/sdc -s -n cluster

4. Make sure that all other nodes see the newly created partition on /dev/sdc using sbdutil -f command.

NOTE:  before starting Novell Cluster Services, make sure all nodes are able to see the new SBD partition. You may need to restart your cluster nodes if the newly created partition is not available or visible.

5. Start NCS using rcnovell-ncs start and check it.
