Still evaluating this for my company.

Running VMS with automatic replication. Simulated hardware failure on primary hypervisor. I can see the disk are replicated to the other node. Whats the easiest way to launch those as machines?

You mean ZFS sync replication? How many PVE nodes, two (2) ?

Well, if the VMs were running on the Primary (now offline) node, then first thing to do is to move the VM conf files to the correct directory so you can start them on the second (online) node.

That would be something like "mv /etc/pve/nodes/<offline_node>/qemu-server/1xx.conf /etc/pve/nodes/<online_node>/qemu-server/" .
Then, you should be able to see this VM on the second (online) node webgui and start it ... Repeat same steps for the other VMs.

*Important* If you have only 2 PVE nodes, then you must ensure that the cluster is quorate by temporary issuing "pvecm expected 1" on the surviving (online) node console. If you miss this step, then the /etc/pve mount will *not* be writable, hence you won't be able to move the vm.conf to the correct location, as described above ...
