Is there an order in which fencing takes place

Solution Verified - Updated -


  • Does cluster node fencing run parallel or sequentially
  • During cluster testing we notice that fencing of two nodes is done sequential.
  • At about 20s the cluster is aware that 2 nodes have failed, but only 1 is fenced.
  • The second node is fenced after 40s.
