RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.
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 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
