Doc Text:
Cause: Pcs validate insufficiently whether is an entered id of a group available (during the run of "pcs resource create"). Consequence: Pcs produces invalid cib and ends with an error message. From such error message it is difficult to identify the cause. Fix: Pcs validate the entered id of group more precisely. Result: Pcs provides an error message with a clear explanation of what is wrong.

Description Ivan Devat 2016-10-05 13:50:02 UTC 
Description of problem:
"pcs resource create" produces invalid cib when group id is already occupied with non-resource element.

How reproducible: always


Steps to Reproduce:
1.
> chose some non-resource element id.
[vm-rhel72-1 ~] $ pcs cluster cib | grep "id=\"cib-bootstrap-options-cluster-name\""
        <nvpair id="cib-bootstrap-options-cluster-name" name="cluster-name" value="devcluster"/>
2.
> try use it as group with "pcs resource create"
[vm-rhel72-1 ~] $ pcs resource create dummy Dummy --group cib-bootstrap-options-cluster-name

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

Expected results:
Error: 'cib-bootstrap-options-cluster-name' cannot be used as group name (is already used as name for another element)

Additional info:
The same problem is with "pcs resource group add" command, for example:

[vm-rhel72-1 ~] $ pcs resource | grep D1
 D1     (ocf::heartbeat:Dummy): Started vm-rhel72-3
[vm-rhel72-1 ~] $ pcs resource group add cib-bootstrap-options-cluster-name D1
Error: Unable to update cib
Call cib_replace failed (-203): Update does not conform to the configured schema
<cib...
