5.7. Activating Logical Volumes on Individual Nodes in a 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.

You can also activate logical volumes on individual nodes by using LVM tags, which are described in Appendix D, LVM Object Tags. You can also specify activation of nodes in the configuration file, which is described in Appendix B, The LVM Configuration Files.
