Reading the emails from that specific night, I saw this message:

 The node 'proxmox01' failed and needs manual intervention.

 The PVE HA manager tries to fence it and recover the
 configured HA resources to a healthy node if possible.

 Current fence status: SUCCEED
 fencing: acknowledged - got agent lock for node 'proxmox01'

This seems to suggest that the cluster is confident that the fencing
succeeded. How does it determine that?
