Hi digimer, I would like to take your offer and asking the following:
The API documents says nothing about the correct way of giving messages back to the stonith daemon. So, what is the right way to write error/warn/info messages. Looking at the scripted agents available I can find a nice mixture of using STDERR and STDOUT. What is the rule here? Can you give insights, whether STDOUT/STDERR is captured by the calling program and logged somewher (and where)? By the way: How is it going with merging the stonith/fencing API? ;-) Best regards Andreas -----Ursprüngliche Nachricht----- Von: Digimer [mailto:li...@alteeve.ca] Gesendet: Dienstag, 11.

The rest of the document is accurate though. If you build an agent to follow that API, it will work with red hat's cluster and pacemaker. In the meantime, it's not ideal, but if you call any other fence agent and pass '-o metadata', you will see the output that the cluster expects. It should be easy to adapt to your new agent. If you have any trouble, please don't hesitate to ask here and we will do our best to help. digimer On 06/11/2013 07:04 AM, Andreas Mock wrote: > Hi all, > > we need to implement a fence_agent (stonith agent) for > cman/corosync/pacemaker (RHEL 6.x).
