Deactivate Cluster without reboot nodes

[freebee]

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.

 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.

I dont know what state your cluster is in now. Just pointing you to resources that might help you. It sounds like you are removing nodes from cluster. You can review other similar posts:

Please make sure you understand what you are doing before running commands.

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

If there is nothing else wrong with your system (and you should check that there isnt) then taking one node out of 3 will leave the other two with Quorum. They should still be functional.
