Description Radek Steiger 2015-03-05 07:45:50 EST
> Description of problem:

If a grouped/cloned/MS resource already exists in a cluster and a new resource, which name is identical to an ID of that group/clone/MS, an invalid CIB is produced instead of a proper error message.

We could get an inspiration from adding a colliding resource ID, where we have a proper error message:
"Error: unable to create resource/fence device 'dummy0', 'dummy0' already exists on this system"


> Version-Release number of selected component (if applicable):

pcs-0.9.137-10.el7


> How reproducible:

Always


> Steps to Reproduce:

1. pcs resource create dummy0 Dummy --clone
2. pcs resource create dummy0-clone Dummy


> Actual results:

Error: Unable to update cib
Call cib_replace failed (-203): Update does not conform to the configured schema
...


> Expected results:

"Error: unable to create resource/fence device 'dummy0-clone', 'dummy0-clone' already exists on this system"
