What is a Highly Available LVM (HA-LVM) configuration and how do I implement it?

Solution Verified - Updated -

Issue

  • How can I configure my cluster service or resource to activate and monitor shared LVM volumes?

  • Uncontrolled simultaneous access to shared storage can lead to data corruption. Storage access must be managed like any other active/passive service - it must only be active on a single machine at a time.

  • Is there a way to configure LVM volumes for active/passive use in a High Availability cluster?

Environment

  • Red Hat Enterprise Linux (RHEL) 6 or 7 with the High Availability Add On
  • rgmanager or pacemaker resource management
  • LVM is to be used in an active/passive manner (only one node will need access to a particular volume at a time)
