Hi all - If all you want to do is float an IP, Linux-HA will work, but a simpler solution could be, say, keepalived and vrrpd.
I you would like to also manage cluster resources, Linux-HA is your best solution. I would agree that it has a steep learning curve, and it's a pain, but it does exactly what you want, and more. It will handle all of your cluster resources - We've used it for MySQL, DRBD, OCFS2, Asterisk, and others. Other options include virtualMonkey and/or Linux Virtual Server ...But I would NOT agree with Itay's "I would recommend not using Linux-HA for any means." Linux-HA is the PROPER open solution to clustering, and just 'cause it's hard to figure out doesn't mean that you should choose a less appropriate product.
