[ClusterLabs] Minimal metadata for fencing agent

Thanks for your answer Thomas and sorry for messing up the layout of
messages - I was trying to write from a mobile phone using gmail... I
was able to put something up using what I found on the web and my own
writing. My agent seems to do what it has to, except for sending
proper metadata. I found the following information: "Output of
fence_agent -o metadata should be validated by relax-ng schema
(available at fence/agents/lib/metadata.rng)." Checked this location,
but I am totally noob regarding to XML. There is a pretty extensive
structure there, and what I need is to prepare a minimal agent to be
used locally by me just to check if the whole thing makes sense at

Do you have any idea as to what is the minimal set of XML data that
fence agent has to send to stdout? Or any way to work around this?
Just for testing purposes.

Best regards,
