Hi, I had a general question about Pacemaker to see if it would work for a somewhat unique situation. I have a cluster of 10 active machines + 2 standby that each have 3 interfaces (2 control, 1 management). I want each of the control interfaces to use virtual IPs, such that if any of those 10 nodes fail, one of the two standby nodes can assume the virtual IPs of the failed node. For the virtual IPs, I wanted the failover to happen entirely in userspace and essentially just receive a notification that a node failed, and allow my application on the standby node to do all of the virtual IP reconfiguration. By userspace I mean that these interfaces are typically not configured by Linux, so the failure of those interfaces and the configuration would be done by a user script.
The reason I'm looking at pacemaker is it appears to be robust on node failure detections, and the STONITH is something I'd like to do. Is this something pacemaker could be configured to do, and if so, which part of the documentation should I focus on?
