Run 173 left node B with healthy corosync (2-member primary component, both
links connected) but no /etc/pve/corosync.conf, no dcdb/status journal lines,
and pvecm status reporting it is not part of a cluster. That file is
database-backed: pmxcfs creates it only when it starts with no config.db and
imports /etc/corosync/corosync.conf, so a surviving standalone config.db would
mean silent local mode.
Capture the package versions, pmxcfs command line, /etc/pve mount, .members,
the config.db and its backup dir, whether the database holds a corosync.conf
row, and the CPG group membership. Read-only; the sqlite3 CLI is not guaranteed
on a PVE node, so fall back to strings.

"Cluster join aborted!" is PVE's generic wrapper; the reason lives only in
the task log on the joining node. Run 172's log said "An error occurred on
the cluster node: cluster not ready - no quorum?", which is what identified
the race. Capture it so the evidence survives cleanup.

The API reports a joined-but-offline node as online=0 with no further
detail, and the cleanup job destroys the nodes minutes later, so the
reason corosync membership never forms has never reached a log. Read
corosync.conf, corosync-cfgtool, pvecm status and the corosync journal
off both nodes while they are still alive. Best-effort: never fails the
caller.
