If a master fails then clients automatically fail over to the slave which becomes the new master. If a master goes down due to hardware failure and you want to bring it back up again on some other machine, take the slave (which is now the master) down, copy its persistent files to another machine and start the master and slave back up again. -- James ------- http://radio.weblogs.com/0112098/
