Wo mache ich ein Fehler ?

Du hast multipath aktiv, obwohl nur ein Pfad genutzt wird.
Mit multipath ist deine Disk dem Gerät /dev/mapper/mpath0 zugewiesen und dann kannst du kein LVM mehr direkt auf der Disk anlegen, sondern musst das auf dem multipath device tun.

Vielen Dank für die Rückmeldung.
Ich habe mich am Proxmox Wiki orientiert, habe es so gelesen das man Multipath einrichten muss in Verbindung mit iSCSI.

D.h. ich brauche es nicht.
Hast du ein Tipp für mich wie "multipath" am unkompliziert los werden kann ?
 
Wenn du mehrere Pfade (IP Netze) benutzen möchtest für Redundanz und Performance, dann benutzt man Multipath.
Du könntest die Multipath Tools deinstallieren und nach einem Reboot sollte dann alles wie vorher sein.
Ich habe aber noch nie Multipath deinstalliert.

Ok, danke für die Erklärung war mir so nicht klar. Habe ich wohl missverstanden.
Werde die nächsten Tage versuchen "Multipath" zu deinstallieren.
