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.

Description Radek Steiger 2015-03-03 15:22:36 UTC 
> Description of problem:

If an orphaned resource exists in a cluster status (e.g. orphaned="true" in crm_mon -X output), GUI fails to work properly due to an attempt on parsing non-existent attributes.

Orphaned resources are not very common, but whenever they appear, pcs GUI should be able to handle them properly. We can deal with them in the command line:

# pcs resource
 dummy1	(ocf::heartbeat:Dummy):	 ORPHANED Started (unmanaged) 
# pcs resource show dummy1
Error: unable to find resource 'dummy1'

# pcs resource cleanup
All resources/stonith devices successfully cleaned up
# pcs resource
#

User can use the cleanup as a temporary 'fix'.


> Version-Release number of selected component (if applicable):
pcs-0.9.137-10.el7


>How reproducible:
Easily 


> Steps to Reproduce:

1. Create a resource
2. Make it orphaned by removing the corresponding primitive tag with 'pcs cluster edit'
3. Open the cluster in a GUI


> Actual results:

Nodes are reported to be stopped, no resources nor any other information is shown.


> Expected results:

GUI keeps on working properly.

Comment 4 Tomas Jelinek 2015-07-13 12:44:21 UTC 
Before Fix:
[root@rh71-node1 ~]# rpm -q pcs
pcs-0.9.141-1.el7.x86_64
[root@rh71-node1:~]# pcs resource create delay delay startdelay=0 stopdelay=10
[root@rh71-node1:~]# pcs resource delete delay --force
Deleting Resource - delay
[root@rh71-node1:~]# pcs resource | grep delay
 delay  (ocf::heartbeat:Delay):  ORPHANED Started rh71-node2

Open the cluster in a GUI. Nodes are reported to be stopped, no resources nor any other information is shown.



After Fix:
[root@rh71-node1:~]# rpm -q pcs
pcs-0.9.142-2.el7.x86_64
[root@rh71-node1:~]# pcs resource create delay delay startdelay=0 stopdelay=10
[root@rh71-node1:~]# pcs resource delete delay --force
Deleting Resource - delay
[root@rh71-node1:~]# pcs resource | grep delay
 delay  (ocf::heartbeat:Delay):  ORPHANED Started rh71-node2

Open the cluster in a GUI. GUI works properly.
