My first HA setup is for a squid proxy where all I need is to move an IP
address to a backup server if the primary fails (and the cache can just
rebuild on its own). This seems to work, but will only fail if the
machine goes down completely or the primary IP is unreachable. Is that
typical or are there monitors for the service itself so failover would
happen if the squid process is not running or stops accepting connections?
Second question (unrelated): Can heartbeat be set up so one or two
spare machines could automatically take over the IP address of any of a
much larger pool of machines that might fail?
