Guten Abend,
nach einer "missglückten" Cluster-Konfiguration möchte ich dieses Cluster wieder in lokale nodes auflösen.
Aktueller Status: Auf beiden Nodes sind virtuelle Maschinen, die erhalten bleiben müssen.

Status server06 (version 5.4-13):
Code:
root@server06 ~ # pvecm nodes

Membership information
----------------------
    Nodeid      Votes Name
         1          1 138.201.123.234 (local)

Status server07 (version 5.4-13):
Code:

Corosync config '/etc/pve/corosync.conf' does not exist - is this node part of a cluster?

Wie ist vorzugehen? Ich habe folgendes Video gefunden: https://www.youtube.com/watch?v=GSg-aeQ5gT8, bin mir allerdings nicht sicher, ob dass die virtuellen Maschinen erhält. Zudem schlägt dies fehl:

Code:
root@server06 ~ # pmxcfs -l
[main] notice: unable to acquire pmxcfs lock - trying again
[main] crit: unable to acquire pmxcfs lock: Resource temporarily unavailable
[main] notice: exit proxmox configuration filesystem (-1)
Vielen Dank für Eure Hilfe!

Morgen! Schaue mal hier da ist schon ein Thread dazu wie man das machen kann. So wie es dort steht habe ich es auch gemacht und hat super funktioniert! Seit dem ist meine hohe CPU Last auch Geschichte.

Guten Morgen! Vielen Dank für Deine Hilfe! Ja, die Anleitung habe ich gestern Abend irgendwann auch gefunden (ich habe nie nach "separate nodes" gesucht...) und nach der hat es tatsächlich funktioniert. Allerdings fand ich dann meinen Thread nicht mehr, um die Antwort hier reinzuschreiben :-( Aber nun ist alles gut :)

OK, erledigt. Habe den Titel auch noch einmal angepasst, vielleicht wird der Thread so leichter bei google gefunden und hilft dem einen oder anderen schneller... :)
