OK I figured it out.
it is quorum specification.
If u have one live node of all, u need execute comand "to pvecm expected 1", then auth is ok

Hi,

that's by design, you should consider adding a third node to the cluster again because a cluster needs at least three nodes.
You can also add a QDevice as your third node:
