[Pacemaker] Question: How many nodes can join a cluster?

Hello, I'm creating a presentation about a virtual Linux-HA Cluster. I just asked me how many nodes pacemaker can handle. Mr. Schwartzkopff wrote in his Book that Linux-HA version 2 can handle up to 16 Nodes. Is this also true for pacemaker? --- Mit freundlichen Grüßen / Best regards Andreas V

Re: [Pacemaker] Question: How many nodes can join a cluster?

I want to point out why a virtual cluster is better than a physical one. In my eyes it’s because of the power usage, cooling and you need less space. I think it’s easier to cool down one server rack than a room full of tower. In one rack you put, let’s say ten ESX server. On every ESX server you
