Doc Type: Bug Fix
Doc Text:
Cause: User tries to manage constraints, attributes and other properties of grouped, cloned or multistated resources in web UI. Consequence: In web UI were displayed only primitive resources. There was no way to set attributes, constraints and other properties separately for parent (group/clone/master-slave) resource and child (primitive) resource. Fix: Resources are displayed in tree structure. It is possible to view and edit all resource elements (groups, clones, master-slaves, primitives) independently. Result: User now can manage constraints, attributes and other properties of groups, clones, multistates and primitive resources independently.

Description Radek Steiger 2015-02-05 16:18:19 UTC
We need a tree-like view of resources what were grouped, cloned, or multistated to be able to set attributes, constraints and other properties per both parent and child resource elements.

Comment 7 Tomas Jelinek 2015-08-10 13:18:07 UTC
Before Fix:
[root@rh71-node1 ~]# rpm -q pcs

Resources displayed in a flat structure. When setting an attribute or a constraint to a cloned or grouped resource it is not possible to set it specifically to parent or child resource.

After Fix:
[root@rh71-node1:~]# rpm -q pcs

Resources are displayed in a tree view. It is possible to edit settings of a clone, a master/slave resource and a group and settings of its child resources independently.

Comment 10 Tomas Jelinek 2015-08-14 11:44:11 UTC
Before Fix:
[root@rh71-node1 ~]# rpm -q pcs

Using web UI try to create an ocf:pacemaker:Dummy resource. An ocf:heartbeat:Dummy resource is created instead.

After Fix:
[root@rh71-node1:~]# rpm -q pcs

Using web UI try to create an ocf:pacemaker:Dummy resource. An ocf:pacemaker:Dummy resource is created.

Comment 14 Tomas Jelinek 2015-09-01 11:48:35 UTC

[root@rh71-node1:~]# rpm -q pcs

After pcsd has been stopped on one node, cluster details are properly displayed in web UI. It works also when pcsd has been stopped on two out of three nodes.

Node attributes and fence levels are displayed in web UI for both online and offline nodes.

Comment 16 Tomas Jelinek 2015-09-07 09:13:49 UTC
Before Fix:
[root@rh71-node1 ~]# rpm -q pcs

Web UI reloads cluster status upon each change of cluster settings done in the UI. This can lead to loading cluster status in parallel which unnecessarily takes cluster and browser resources.

If user changes resource settings using web UI (e.g. meta attributes) and removes the last constraint of the resource while web UI is loading cluster status, the constraint will remain displayed in web UI even though the constraint was successfully removed from the cluster.

After Fix:
[root@rh71-node1:~]# rpm -q pcs

If a cluster status reload is triggered in web UI while another request to refresh the cluster status is already in progress, the new request is put into a queue and run only after the previous request is finished.

Resource constraints are removed properly from web UI.

Comment 18 Tomas Jelinek 2015-09-16 13:36:52 UTC
After Fix:
[root@rh71-node1:~]# rpm -q pcs

It is possible to create a disabled resource using web UI.

When removing the last resource from a cluster using web UI, the resource settings are no longer displayed.

In the resources page running resources are displayed in blue color, resources with warnings are displayed in orange color, resources with errors are displayed in red color.

Create a new group of resources. Try to add another resource to the group. The group name is available in the group name select.

Create a clone resource. Add an ordering set constraint containing the primitive from the clone and some other resource. An error message is displayed stating the clone shoud be used instead of the primitive. It is possible to force the constraint creation, the constraint is then created on the primitive resource.

Comment 22 Tomas Jelinek 2015-09-22 11:23:30 UTC
After Fix:
[root@rh71-node1:~]# rpm -q pcs

Resource details are not displayed in a group, clone and master/slave page when switching to it quickly from a primitive resource page.

Multi-state resources are displayed as running when a status of a cluster running older version of pcs is displayed.
