High availability with multi master?

[empr]

Hi,

I was wondering if it was possible to have multiple (+2) servers running proxmox in HA, with both servers sharing the load of guests.

For what I understood after reading the docs, proxmox HA works with one physical server running and, if it fails, the secondary one will start and run all the guests (or something similar).
I couldn't find anywhere how to have multiple servers running at the same time, each with different guests, in HA mode.

Any ideas?

Thanks!
EM

You can have any number of cluster nodes. All nodes can have running VMs. If one node fails, the VMs from that node will be automatically transfered to another running cluster node.

Will this work with only 2 nodes as well?

Thanks!

Sure. As long as you have a quorum disk (see: http://pve.proxmox.com/wiki/Two-Node_High_Availability_Cluster) and enough free resources (especially RAM) on both nodes, so that all your VMs can run on one node if the other one fails.
