RE: [Linux-cluster] RH Cluster doesn't pass basic acceptance tests -bug in fenced?



Hi,

 

We got the same problem and tried to used qdisk without success.

I managed to create the qdisk but didn't manage to get both nodes registered into it.

 

Could someone please point me to the documentation / description of how to properly set up the qdisk for a 2 nodes-cluster?

 

Thanks a lot,

 

Samuel.

How can I prevent this? This looks like a bug. I don't want fenced to

fence other node south if it already "knows" that it is the one without link.

It is very possible to write a wrapper script for your fencing agent that simply checks the link and refuses to fence when the link is down.  However, this wouldn't really be good in any non-network related fencing situation.

 

The recommendation to use a qdiskd would be a good one and you could even use a link detection script as an arbitrary heuristic in this case.
