Hi Hauke,
I can't find any reference in the crm manual to your command. I don't
either understand what is an unclean location. A cli-* location?
Can you clarify?
Again your setup seems to be opt-in based (sorry I miss used the term in
previous post). Documentation states:
*6.2. Deciding Which Nodes a Resource Can Run On*
There are two alternative strategies for specifying which nodes a resources
can run on. One way is to say that by default they can run anywhere and
then create location constraints for nodes that are not allowed. The other
option is to have nodes "opt-in"... to start with nothing able to run
anywhere and selectively enable allowed nodes.
Your approach follows neither of these options at the moment.
