You have a four-node cluster, where node1 and node2 are connected to some shared storage,
and node3 and node4 are connected to different shared storage.
Now node1 has died and you will not be able to reboot it for some time. Why would you then want
to run clq disable node1?
A.
This will prevent node1 from accidentally rebooting until you explicitly run clq enable node1 on
one of the remaining nodes.
B.
You may want to run the command but it is actually too late. You can only run the disable
option when the node mentioned is still up in the cluster.
C.
This will alter the quorum vote count in the remaining cluster so that if later you also lost node2,
the remaining nodes could continue running the cluster.
D.
This is simply an informational flag. The output of the clq status will specifically show a
maintenance flag for node1, indicating that you recognize it is dead and will not be able to reboot
for some time.
