If it's running heartbeat - it's in _some_ cluster. That's what it
means. You can't do cluster communications without being a cluster.
That's ALL heartbeat is - cluster communications.
If you take away the cluster communications, you have nothing. Nothing
at all.
Uhm. You're contradicting your own "heartbeat makes sense in a one node
configuration too as init-on-steroids" credo.
No I'm not. You're using the term in two different ways in the same
sentence to give the appearance of contradiction - one as "the heartbeat
processes" and one as "all of Linux-HA".
Perhaps this is merely a terminology difference.
What I think perhaps James _meant_ to say was - heartbeat starts up in a
1-node cluster, then later on we want it to merge this 1-node cluster
into some other cluster - becoming part of the Borg Collective (so to
speak). http://en.wikipedia.org/wiki/Borg
But, even then _from heartbeat's point of view_ it's a cluster - just a
really small one. And, it's not a larval stage. It's a full-fledged
cluster.
And, the idea of merging clusters is a useful one - not just for this
case. But, this is, of course, the most obvious case.
