Good summary.<br>

<br>
No; MySQL / Galera needs to be running on all nodes all the time. Pacemaker <br>
is for managing resources which move between nodes.<br>
<br>
If you want something that ensures processes are running on machines, <br>
irrespective of where the floating IP is, look at monit - it's very simple, <br>
easy to configure and knows how to manage resources which should run all the <br>
time.<br>

No; I've largely made this stuff up myself as I've needed it.<br>
