Hi.
We are in a process where we are migrating VMs to new servers and deactivating the old servers.
Everything is ok with process but now I have just only 3 nodes (old) left and some vms to migrate.
How I can deactivate the cluster to not reboot when I turn off one of these 3 nodes ?.
pvecm expect 1 not work (invalid param).
 
Its unclear why you need to keep deactivating the servers. Cant you leave the last 3 online until you are fully migrated?

Other than that "man pvecm" or "pvecm help" are very useful.
Code:
 pvecm expected <expected>

       Tells corosync a new value of expected votes.

       <expected>: <integer> (1 - N)
           Expected votes

I am assuming you did your research and the conclusion was that this is how you want to approach it.

Right. Just for me understand.
I can remove the node, leaving just two. This two nodes will not restart.
Is this right ?.
