Hi,
Usually I use the following steps to delete node from the cluster:
1. #crm corosync del-node <ip_addr>
2. #crm_node -R node --force
3. #crm corosync reload

Instead of steps 1 and 2you can delete certain node from the corosync config manually and run:
#corosync-cfgtool -R

Hi,

I am trying to remove a node from the pacemaker’/corosync cluster, using the command “crm_node -R dl360x4061 –force”.
Though this command removes the node from the cluster, it is appearing as offline after pacemaker/corosync restart in the nodes that are online.

Is there any other command to completely delete the node from the pacemaker/corosync cluster.

Pacemaker and Corosync Versions.
PACEMAKER=1.1.10
COROSYNC=1.4.1
