I have two PVE cluster with ceph, Now I want to Use the same 10G switch for the two ceph, but them have the same ip(10.10.10.1/24)
can I change the ip of one of the ceph?
You can but it is not trivial. To begin with, please read through some of those experiences: One, two, three, four. How big are your clusters? What versions of Proxmox VE are you running exactly?
