What is the recommended LVM configuration when multiple Red Hat Enterprise Linux cluster nodes are accessing the same shared storage?
Issue
- How can multiple systems be confirgured to access the same backend storage?
- When should
clvmd
be used instead of HA-LVM? - I have shared LVM devices. Do I need to do anything special to protect the metadata from being corrupted by multiple nodes accessing the volumes at the same time?
Environment
- Red Hat Cluster Suite 4 / Red Hat Global File System 6.1
- RHEL 5, 6, or 7 with the High Availability and/or Resilient Storage Add On
- Shared storage devices that will be managed by the Logical Volume Manager (LVM)
