I find u really like ocf:heartbeat:anything â€¦â€¦

but i think it’s better to use lsb:[xxx] which can use script in the /etc/init.d/[xxx], then you can add ‘sleep words’ in the start() ï¼šï¼‰

pacemaker is really powerfull.

You can also use MySQL Cluster Manager – http://www.mysql.com/products/database/cluster/mcm/ – or Solaris Cluster – http://www.sun.com/software/solaris/cluster/ – to manage a MySQL Cluster.

@Didier: Pacemaker works very well with Heartbeat and I have been using it for years so it was easier for me to use Heartbeat.

@Didier: sorry, that’s plain wrong. Pacemaker is a spin-off of the Linux-HA project (it’s the continuation of the CRM effort in Heartbeat 2, albeit in a separate project for various good reasons). It supports both messaging layers just fine.

Any specific reasons to pick heartbeat instead of OpenAIS/corosync? While still compatible with heartbeat, pacemaker was rather designed with OpenAIS in mind …

Goodness, Yves! Please stop scaring people with XML dumps. “crm configure show” dumps will do just fine, be much more concise, and easier to read.
