[ClusterLabs] General Capabilities Question

[Cliff Burdick]

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?
