Solution Unverified - Updated -


  • My node was fenced and as soon as it rejoins the cluster now, it reboots again. This has happened over and over every time we boot it back up.
  • When joining the cluster, the node seems to start up but then reboots itself with a message from clurgmgrd about "unable to deactivate"
