This is an interesting option... I can see that it shows me running resources only (not what resources are configured but off). It does show more directly "VM x is on node y"; <resources> <resource id="srv07-el6" resource_agent="ocf::alteeve:server" role="Started" active="true" orphaned="false" blocked="false" managed="true" failed="false" failure_ignored="false" nodes_running_on="1"> <node name="mk-a02n02" id="2" cached="true"/> </resource> </resources> I'd like to avoid writing a new parser as I'll still need to read/parse the CIB anyway to know about off resources, and I have to assume there is a way to determine the same from the CIB itself. How to determine what is running where has to be determinable... digimer >> On Wed, Sep 23, 2020 at 11:04 PM Digimer <li...@alteeve.ca> wrote: >>> Hi all, >>> >>> I'm trying to parse the CIB to determine which node a given resource >>> (VM) is currently running on.
