<div dir="ltr">Hi all - <br><br>If all you want to do is float an IP, Linux-HA will work, but a simpler solution could be, say, keepalived and vrrpd.<br> <br>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.<br>
<br>Other options include virtualMonkey and/or Linux Virtual Server<br><br>...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.<br>

</div>Heartbeat has 2 faces, It can work great or it can fail bitterly.<br>
It has a very steep learning curse before something useful begins to happen.<br>
<br>
cibadmin -Q, crm_attribute are your friends.<br>
<br>
I agree with Itay, from our experience it is indeed buggy but working.<br>
