Removing 3 nodes from 6 node cluster

[brucexx]

I need to remove 3 nodes from a 6 node cluster and they are not coming back , the remaining 3 nodes will be gradually retiring after moving all the VMs. I have done that before few years ago with pvecm expected command. Is there any other way ? There will be no HA on remaining nodes , is expected 3 or 2 best for 3 nodes ?

Thank you

Removing for an lxc/vm empty node "pvecm delnode Nodename".
Minimum for a cluster should be 3 nodes (even some are running as 2 nodes plus Q-device) for quorum of 3.

I did pvecm expected 3 which gave me quorum. I guess what I did not realize was that the expected command with x nodes is available only after you remove in my case it was the 3rd node. Before I was getting an error. Once the 3rd node was removed (in 6 node cluster) pvecm expected 3 command did the job.

Thank you

What Waltar said. as long as you're removing the nodes you shouldn't need to mess with quorum nodes expected.
