Hi! When starting pacemaker (1.1.19+20181105.ccd6b5b10-3.10.1) on a node that had been down for a while, I noticed some unexpected messages about the node name:
pacemakerd: notice: get_node_name: Could not obtain a node name for corosync nodeid 739512332 pacemakerd: info: crm_get_peer: Created entry a21bf687-045b-4fd7-9340-0562ef595883/0x18752f0 for node (null)/739512332 (1 total) pacemakerd: info: crm_get_peer: Node 739512332 has uuid 739512332 Seems UUID and node ID is mixed up in the message at least... pacemakerd: info: crm_update_peer_proc: cluster_connect_cpg: Node (null)[739512332] - corosync-cpg is now online pacemakerd: notice: cluster_connect_quorum: Quorum acquired pacemakerd: info: corosync_node_name: Unable to get node name for nodeid 739512332 pacemakerd: notice: get_node_name: Defaulting to uname -n for the local corosync node name pacemakerd: info: crm_get_peer: Node 739512332 is now known as h12 ... pacemakerd: info: main: Starting mainloop pacemakerd: info: pcmk_quorum_notification: Quorum retained | membership=172 members=2 pacemakerd: info: corosync_node_name: Unable to get node name for nodeid 739512331 pacemakerd: notice: get_node_name: Could not obtain a node name for corosync nodeid 739512331 pacemakerd: info: crm_get_peer: Created entry f4ef35e4-1b49-4e48-916b-bb0fab7c52c9/0x1876820 for node (null)/739512331 (2 total) pacemakerd: info: crm_get_peer: Node 739512331 has uuid 739512331 ... pacemakerd: info: corosync_node_name: Unable to get node name for nodeid 739512331 ... pacemakerd: notice: get_node_name: Could not obtain a node name for corosync nodeid 739512331 pacemakerd: notice: crm_update_peer_state_iter: Node (null) state is now member | nodeid=739512331 previous=unknown source=pcmk_quorum_notification pacemakerd: notice: crm_update_peer_state_iter: Node 12 state is now member | nodeid=739512332 previous=unknown source=pcmk_quorum_notification pacemakerd: info: pcmk_cpg_membership: Node 739512332 joined group pacemakerd (counter=0.0, pid=32766, unchecked for rivals) stonith-ng: info: corosync_node_name: Unable to get node name for nodeid 739512332 stonith-ng: notice: get_node_name: Could not obtain a node name for corosync nodeid 739512332 What's that?
