We have a couple of containers where data changes a lot. One is a mail system.
Currently for high availability we use drbd and heartbeat. So disk writes always occur at two physical servers. If the primary system fails , the other takes over and has all the emails. But heartbeat does not work with Proxmox 2.0 .
According to http://pve.proxmox.com/wiki/High_Availability_Cluster#System_requirements shared storage is needed to make a Proxmox VE HA Cluster.
With a 3 node cluster, I do not want to set up a 4-th system for Shared storage , as that would be a single point of failure .
We have plenty of disk space on each node.
Is it a good idea to set up shared storage at each node?
If so what method should be considered?
thanks.
