Try here, since You are already thinking of using 2 machines: http://linux-ha.org/LinuxFailSafe/ Works rather well with IP, MAC and Oracle/SAP failover. I believe there is a driver for MySQL, if not You shouldn't t have much trouble writing one, examples are provided. It's all open source, same code _base_ as IRIX FailSafe (HA on SGI machines for the past 7? years). Since this is really off-topic, if You have any further questions, You probably should ask me off the list. I would only suggest using either DRBD or shared-SCSI for storage. --------------------------------------------------------------------- Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail <[EMAIL PROTECTED]> To unsubscribe, e-mail <[EMAIL PROTECTED]> Trouble unsubscribing?
