[Linux-HA] RE: One-way failover?

[Eddie C]

There is a project on sourceforge called mysql-ha. Its not part of linux HA
put it deals with switching servers from master to slave in the event of a
failure. Seems like never mysql 5.0 with multi-master is a better way to go.

There is a great article on onlamp about it. I posted it to this list a
while back.
