LVM metadata corruption when rgmanger starts at the same time on multiple nodes on Red Hat Enterprise Linux

Solution Verified - Updated -

Issue

  • RHCS: Checksum error occurs on HA-LVM
  • We modified the cluster.conf manually and loaded the configuration, but the cluster service didn't start up again and it logged checksum error of LVM header on the shared disk.

Environment

  • Red Hat Enterprise Linux (RHEL), including:
    • Red Hat Enterprise Linux Server 4 (with Cluster Suite Add Ons)
    • Red Hat Enterprise Linux Server 5 (with the High Availability and Resilient Storage Add Ons)
    • Red Hat Enterprise Linux Server 6 (with the High Availability and Resilient Storage Add Ons)
  • Red Hat High Availability Cluster with 2 or more nodes.
  • Rgmanager cluster service manager

    • Tagging-variant HA-LVM resource managed by rgmanager.
    • Issue occurs when rgmanager is started at exactly the same time on 2 or more nodes.
