Yes.
If you plan accordingly and set up the nodes with zfs storage from the beginning, you can have them replicate the container and vom images to all nodes every x minutes. That way you don’t need external storage.

Cyber@feddit.uk 5 days agoI’ve not looked at Proxmox clusters - can they restart VMs on a different host if they’re all using the same shared storage?
Yes.

Yup, shared storage is a requirement. I’m using a combination of Ceph and NFS at the moment, but I wouldn’t recommend Ceph unless you’ve got a 10gb connection between nodes.
Here’s a guide to set up high availability with Proxmox: https://kiwicloud.ninja/2024/02/improved-high-availability-ha-for-vms-on-proxmox-ve-pve/
