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 does not detect that crm_resource is not able to ban stopped resource when node is not specified, because it is not possible to locate a node on which the resource is running.
Consequence:
crm_resource error message is presented to the user. The message is not very helpful because it is crm_resource specific.
Fix:
pcs detects that resource was not moved because crm_resource was not able to locate the resource node, and provides an explanatory error message.
Result:
User is informed about the cause of the error and how to avoid it.
Description of problem:
Trying to move/ban a stopped resource without specifying the target node gives an error:
Error: error moving/banning/clearing resource
Resource 'dummy' not moved: active in 0 locations.
You can prevent 'dummy' from running on a specific location with: --ban --host <name>
Error performing operation: Invalid argument
Move/ban of a running resource works both with and without specifying the target node. Move/ban of a stopped resource with specifying the target node works too.
Version-Release number of selected component (if applicable):
pcs-0.9.115-32.el7
How reproducible:
always
Steps to Reproduce:
1. stop some resource e.g. 'pcs resource disable dummy'
2. try to move stopped resource without specifying the node: 'pcs resource move dummy'
Actual results:
Resource is not moved and an error message is presented to the user.
[root@localhost ~]# pcs resource move dummy
Error: error moving/banning/clearing resource
Resource 'dummy' not moved: active in 0 locations.
You can prevent 'dummy' from running on a specific location with: --ban --host <name>
Error performing operation: Invalid argument
[root@localhost pcs]# echo $?
1
Expected results:
Inform user that it is not possible to move/ban a stopped resource without specifying the target node.
Additional info:
pcs uses crm_resource for moving and baning the resources. crm_resource --move requires a target node specified otherwise it bans the resource on the node where the resource is currently running so the resource is moved to some other node. If the resource is stopped there is no node to put the ban on so crm_resource gives an error.
Test:
1. create and stop a resource
[root@localhost ~]# pcs resource create dummy Dummy
[root@localhost ~]# pcs resource disable dummy
2. try to move the resource and check for error message
[root@localhost ~]# pcs resource move dummy
Error: You must specify a node when moving/banning a stopped resource
3. try to ban the resource and check for error message
[root@localhost ~]# pcs resource ban dummy
Error: You must specify a node when moving/banning a stopped resource
