Hello there! I'm trying to configure a Proxmox cluster using a VPN from 2 different geographic sites with a total of 3 nodes. I'd like to enable Ceph cluster using ODS disks but it looks like ceph Monitors and ODS configurations need to use a network in the same segment like 192.168.2.0/24 If...

Hello all, we are facing a strange issue. We have a two node Cluster plus QDevice on the latest PVE version with HA enabled on the VMs. We are currently in the process of testing the cluster. In order to test the fencing and HA recovery, we pulled the network from one of the two nodes (Node 1)...

Hi all, I set up a cluster with 2 nodes running Proxmox 8.2 + 1 qdevice. I have a VM that provides critical network services (DNS, proxy server, etc). This VM rarely changes, so live replication is not required. What I'm looking for: A way to have this VM shutdown, but available to start up...

After going down many rabbit holes, I have finally come to the conclusion that the best solution (for my office) is a Proxmox cluster with 4 nodes. Depending on my final build, I might be able to only have 3. For now, I will use both proxmox backup and veeam to backup my VMs to a TrueNAS box...

Hey guys, I hope everyone is okay. I would like to know if it is possible to synchronize two different clusters with similar structures? The objective would be to create a datacenter for disaster recovery and/or contingencies in the event of loss of communication. it's possible?

Hi everyone, I'm designing a new 3-node cluster. It's not the first cluster I make but it's the first with a full-mesh Ceph network (no dedicated switch) . Each node has a double 10G NIC and they're already physically connected each other. So I've been reading the docs and I think the best...
