How to Activate the Logical Volumes on Individual Cluster Member Nodes in a RHEL Cluster?

If you have LVM installed in a cluster environment, you may at times need to activate logical volumes exclusively on one node.

To activate logical volumes exclusively on one node, use the lvchange -aey command. Alternatively, you can use lvchange -aly command to activate logical volumes only on the local node but not exclusively.


You can later activate them on additional nodes concurrently.
