i have some serious issues with mysql master-slave and rapid fail over.
imho, and i might be wrong, this functionality "is not quite there yet".
the basic problem: master fail over from node1 to node2 and back again
makes node2 try to parse the binlog from the very start.
"CHANGE MASTER TO" does not honor the slave's last position for a given
master upon fail over and/or the binlogs on the master are never reset
thus leading to duplicate parsing of the very same binlog.
i'll see to a more detailed report but am kind of swamped in work right
