Hello, I'm running PVE8.0 at home. Multiple users working from home with Windows VMs. Many small Linux VMs doing lots of low-bandwidth stuff. I'm in the process of setting up a 3-node cluster for HA. All 3 nodes have identical hardware. All 3 nodes are on a 10GB fiber network. All 3...

I have a 6-node cluster that I recently (two nights ago) upgraded to 8.0.4. This cluster has been going strong with no issues at all until after the upgrade to 8.0.4. The upgrade went smoothly with zero issues at all. Now, one node in the cluster keeps 'greying out' on the GUI. I rebooted the...

Hello, I have a situation where I share a server with another business and it has come time where we need to part ways and so I need to transfer my VMs off of this server and onto a separate server. I would need this separate server to be stand-alone when all is said and done. How would I go...

I'm trying to figure out the best way to ensure corosync has its own network. Please let me know if any of these points weren't ideal and why: I created a VLAN with no gateway (just a space on my switch with a unique subnet) 10.5.0.X and set all 8x of my nodes to addresses on that subnet. I...

Hello everyone, so a few days ago the electricity failed in my homeoffice and the small homelab for Home purposes failed. One node was complelty failing until the point the ssd inside was basically dead. It could boot, sometimes but after a few minutes went offline again due I/O error. I came...

I'm looking to setup a PVE cluster, mostly for the benefit of being able to move VMs from one machine to the other and for high availability. In reading the PvE8 admin guide I came across this line: This is a real bummer since I have a mixed Epyc and embedded Xeon CPU environment. I have...

I've spent so many hours and pulled too many hairs for this already. TLDR: Migrating a VM fails because ssh of the target node listens on IPv6 only (as desired+configured), and migration is attempting connection to IPv4. All I want is the connection to go through IPv6, or the VPN IP. The...

Hello, I have a cluster and one of the nodes is a ZimaBoard. Everything runs fine, but when I try to do a backup of my CT the backup job is stuck and nothing is happening. It doesn't matter if the backup storage is the local SSD or a NFS or PBS - same behaviour. Example: Node name: "darwin"...

Hello all, this is my first post on the forum. I have a proxmox cluster installation with ceph that is broken and need help recovering it. After a network device stole the IP address of one of the nodes, ceph went down and never recovered. I tried troubleshooting with a proxmox silver partner...
