[Pacemaker] Full API description for Fence Agent

[Andreas Mock]

Hi all,

we need to implement a fence_agent (stonith agent) for
cman/corosync/pacemaker (RHEL 6.x). I found the following documentation
https://fedorahosted.org/cluster/wiki/FenceAgentAPI

But in this document the required metadata action is not
described. Can anybody point me to a documentation which
is complete?

Where is the schema of the xml returned by 'metadata'?

What has to be done that a fence_agent can also be used
by pacemaker?

What is the right return code of action 'metadata'?

Is there some explanation how the stonith/fence parts
play together?

Best regards
Andreas Mock
