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.

Fixed In Version: pcs-0.10.6-1.el8 Doc Type: Bug Fix
Doc Text:
Cause: Web ui backend internally uses syntax of a command `pcs constraint colocation add` that is not supported yet. Consequence: Adding a colocation constraint from the web ui always fails. Fix: Web ui backend has been fixed to use current syntax of command `pcs constraint colocation add`. Result: Adding a colocation constraint from the web ui succeeds.

Description Michal Mazourek 2020-05-07 14:45:11 UTC 
Description of problem:
When adding a colocation constraint in the web UI, the error message is shown: 'Unable to add constraint (Bad Request)'. Since this problem wasn't present in RHEL7 and first occurred in RHEL8, it is a regression.  


Version-Release number of selected component (if applicable): 
found in pcs-0.10.4-6.el8


How reproducible:
always


Steps to Reproduce:
1. Log in to the web UI
2. Add cluster
3. Go to the resources page of the cluster
4. Add 2 Dummy resources
5. Click on 'Resource Colocation Preferences (0)' in the 'Edit Resource' page of one of the resources.
6. Fill in the name of the other resource, set 'Together' in 'Together/Apart' field and click 'Add'


Actual results: Alert message with 'Unable to add constraint (Bad Request)' text is shown and the constraint is not created.


Expected results: The constraint is created.


Additional info: After discussion with developer, it seems like the syntax of 'pcs constraint colocation add' is now more strict in RHEL8, which causing the issue.

proposed fix

Test:
Create new colocation constraint in web UI. It should work.
Comment 4 Miroslav Lisik 2020-06-11 14:20:16 UTC 
Test:

[root@r8-node-01 pcs]# rpm -q pcs
pcs-0.10.6-1.el8.x86_64

1. Create 2 Dummy resources in GUI
2. Go to the resource details form and add a Colocation constraint
3. Result: Colocation constraint is created and 'Resource Colocation Preferences' updated
