How to change totem token timeout value in a RHEL 5, 6, 7, or 8 High Availability cluster?

Solution Verified - Updated -

Issue

  • I have a Red Hat Enterprise Linux cluster using the default token timeout value of 10 seconds. I want to increase this value to make the cluster more resilient against unresponsive nodes, network interruptions, or similar delays.
  • I need to modify the cluster poll rate.
  • How do I change/increase/modify cluster heartbeat token timeout value?
  • How do I avoid problems due to a temporary network glitch in a cluster?
  • How do I prevent cluster fencing due to temporary network split?
  • How do I increase the amount of time required to detect failed nodes?
  • How long will a Red Hat cluster wait before it fences the unresponsive node?

Environment

  • Red Hat Enterprise Linux 5 (with the High Availability Add-On)
  • Red Hat Enterprise Linux 6 (with the High Availability Add-On)
  • Red Hat Enterprise Linux 7 (with the High Availability Add-On)
  • Red Hat Enterprise Linux 8 (with the High Availability Add-On)
