Guten Morgen liebes Forum,

ich hab mich jetzt zwei diverse Stunden mit folgendem Problem rumgeschlagen, komme aber keinen Schritt weiter:

Ich versuche einen Server in einen Cluster mit Corosync und Pacemaker einzubinden, scheitere jedoch beim Start von Corosync 1.4.2

und auch lauscht nichts auf dem Port

Die Ports sind auch in der UFW freigegeben (deaktivieren selbiger bringt auch nichts)

In der Hosts sind die Namen entsprechend hinterlegt

10.8.0.21 cluster_esp_prod
10.8.0.11 cluster_esp_fallback
10.8.0.16 cluster_esp_monitor


Und in /etc/corosync/corosync.conf ein entsprechendes Setup hinterlegt


...
interface {
member {
memberaddr: 10.8.0.21
}
member {
memberaddr: 10.8.0.11
}
member {
memberaddr: 10.8.0.16
}

# The following values need to be set based on your environment
ringnumber: 0
bindnetaddr: 10.8.0.0
mcastport: 5405
}

transport: udpu
...


Das selbe Setup läuft auf den beiden anderen Kisten wie erwartet, aber diese eine will einfach nicht und ich komme nicht hinter den Grund der Fehlermeldung.

Ich habe auch schon einen simplen Echoserver auf der selben 10.8.0.11 und 5405 problemfrei gestartet und getestet.
Momentan bin ich etwas Ratlos, hat einer von Euch eine schlaue Idee?
