Hi, I have two cloned resources in my cluster that have the following
properties:
* There are a maximum of two instances of R1 in the cluster, with a maximum of
two per node
* When any instance of R1 is started on a node, exactly one instance of R2
should run on that node
When I configure this, and verify the configuration with "crm_verify -LV", I
get the following error:
clone_rsc_colocation_rh) error: Cannot interleave R2-clone and R1-clone
because they do not support the same number of instances per node
How can I make this work? Any help would be greatly appreciated.
Current configuration is as follows:
<resources>
<clone id="R1-clone">
<meta_attributes id="R1-clone-meta_attributes">
<nvpair name="interleave" value="true"
