Can I enable Proxmox HA with 2 Nodes + QDevice + Local storage?

Hi @logui ,
The goal of the HA is to ensure continued operation of services. In PVE its done by moving the execution context of the VM or LXC from one node to the another.
While its possible to not have a dependency on stored disks (PXE boot), this is not your situation. Your VMs will have disks with, at the very least, OS.
For the HA services to be able to move a VM from one node to another - the disk needs to be available on the target node. If your disks are local - that presents a problem.
One option to have HA with local storage is to set up ZFS replication. PVE provides interface to do so. As the name implies, ZFS replication depends on you using ZFS for your disks.
If you have an option to use NFS - that would be the simplest solution.
You do need 3 nodes for proper cluster operation. The 3rd/vote node can be a simple container or even a raspberry PI.
