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

[Krikler, Samuel]

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.

	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.
