[Pacemaker] How to create OCF Resource Agents

[Paul Osier]

I ran that and it just says:

* rc=3: Your agent does not support the validate-all action

I thought validate-all was optional. But, that being the case, how do I
set it up? My script should just start/stop/monitor SER, there are no
variables being passed to it.

Sorry, I'm just learning Pacemaker and how it works.

Thanks.

Pacemaker comes with a tool called "ocf-tester", which will help you
find out what your RA's problem are.
