Hello, please help me solve the problem, there were 2 nodes, the first node was converted into a cluster, the second one was added to the cluster. The screw on the first node fell down (in errors, part of the vm could not be saved). The question (I did not find an exact, painless answer on the Internet) is how to withdraw the second node from the cluster, leaving the vm on the second node in working order? (or how you can transfer the cluster role to the second node and remove the first one from the cluster, when the first node is turned off, the VMs on the second node work, but you can’t log into the web face.)
 
Hi,

it should be possible to remove the broken node from the cluster [1]. You have to make sure the broken node doesn't connect to the cluster anymore and then call:
Code:
pvecm delnode [node name]

After this, it should be a single node cluster. It is also possible to remove the cluster from the node [2], but not recommended.

I understand correctly that I need to stop the node that I declared as a cluster, then on the remaining one node enter pvecm expected 1 (in order for there to be a quorum of one vote) and delete the first node declared by the cluster pvecm delnode [node name]. After that, will I still have a working node with running VMs?
I may not correctly interpret the concept of a cluster, is this entity attached to a specific node or distributed to all nodes, and when any of the nodes is disabled, dominance is transferred to one of the remaining working nodes?


Thanks, got it, issue closed

Just a short explanation: You "declare"/start the cluster on one node. But all nodes are equals, so the node where you started the cluster is not more special than the other nodes :).
