Hi Andrew,

sorry for the late answer - I had too many concurrent projects...

That's what I did.

See attachement. Thanks for your help in advance.

Try to fail a resource in "Master". This should also restart the
"Slave".

In "Redaktion" this should drive down "Slave" then "Master" then start
"Master" then "Slave".

This whole configuration is just a simulation of the real thing.

For the real Cluster I will use either init-scripts for the
corresponding resources or convert them to ocf-scripts.
