Not sure if "cluster partitioning" is the right description here, so
I'll try to explain what I want to achieve.
Right now, I have 4 web/application servers, with heartbeat/pacemaker
assigning IPs:
(web1) - (web2) - (web3) - (web4)
There is also a "mysql1" server, used by the webservers, which does not
have heartbeat installed.
"mysql1" server will be a master-master setup, with "mysql1" being
accessed by the webservers, and the other mysql server as a failover.
What I'd like to do, is "web4" being the "failover mysql server" - so
the whole cluster would look like below:
/web4) - (mysql1)
(web1) - (web2) - (web3) - (web4/
Now, if mysql1 dies, I would like one if it's IP addresses (used for
MySQL) be assigned to web4, and only to web4.
mysql1 should never have web* server IP addresses assigned (except the
one used for MySQL, allowed to be moved to web4, and only to web4).
Can I do it with heartbeat/pacemaker? If so, how?
