Can two-node RHEL 7, RHEL 8 or RHEL 9 High Availability clusters be susceptible to fence loops?

Solution Verified - Updated -


  • I have a two-node cluster using pacemaker. Do I need to worry about fence loops like I did with older cman clusters?
  • Does corosync with votequorum have a problem with fence loops where the network goes down, a node gets fenced, and then it fences the other node when it boots back up?
  • How can I avoid fence loops with pacemaker in RHEL 7 or RHEL 8 or RHEL 9?


  • Red Hat Enterprise Linux 7 (with the High Availability Add-on)

  • Red Hat Enterprise Linux 9 (with the High Availability Add-on)
