"StartFilesystem: Could not match <device> with a real device" error when service fails over on Red Hat Enterprise Linux 5

Solution Unverified - Updated -


  • When the node 2 crash or rebooted, why the resource group was not taken over by node1? It seems the node1 failed to acquire the resource group.


  • Red Hat Enterprise Linux Server 5 (with the High Availability or Resilient Storage Add Ons)
  • rgmanager to manage cluster services:

    • A service is configured with LVM and filesystem (fs) resources:
