Problem Summary: When both the global cluster and a zone cluster contain a resource group by the same name, if either resource group has a non-empty value for the RG_dependencies or RG_affinities property, then attempting to remove the other resource group with the same name will fail with a complaint about the existing dependency.
Workaround: Include the –F (force) option in the command to delete the resource group. For example:
# clrg delete -F rg-name
Then, recreate any dependencies or affinities on the remaining resource group with the same name if deleted with the force option.
