      .Support for new `pscd` Web UI features

      The `pscd` Web UI now supports the following features:

      * Moving a cluster resource off the node on which it is currently running

      * Banning a resource from running on a node

      * Displaying cluster status that shows the age of the cluster status and when the cluster state is being reloaded

      * Requesting a reload of the cluster status display

      1. Proposed title of this feature request

      Add resource move and ban commands to PCSD web UI

      --------------------

      2. Who is the customer behind the request?

      --------------------

      3. What is the nature and description of the request?

      Add buttons to the PCSD web UI for `pcs resource move` and `pcs resource ban`, with an optional dropdown for selecting a target node.

      --------------------

      4. Why does the customer need this? (List the business requirements here)

      • Customer administers cluster primarily through web UI, and moving/banning resources is a fairly standard administrative operation. They have had to run these operations from the command line or by manually adding INFINITY/-INFINITY location constraints.
      • Currently they have resources that should be cloned, which they want to be able to ban from one node temporarily. In the absence of a "Ban" button, they are concerned that a user will accidentally click "Disable", thus preventing the cloned resource from running on any node. They have created duplicate non-cloned resources, each constrained to a specific node, to protect against such user error. They would like to replace these with cloned resources when a Ban button is available.

      --------------------

      5. How would the customer like to achieve this? (List the functional requirements here)

      A button for "Move" and a button for "Ban" under "Resources > RESOURCE_ID", with an optional dropdown or autofill box to select a target node.

      --------------------

      6. For each functional requirement listed, specify how Red Hat and the customer can test to confirm the requirement is successfully implemented.

      • Visually verify that the move/ban buttons and their respective dropdown boxes are present under the Resources tab of the PCSD web UI after clicking a resource name.
      • Click the Move button. Verify that there is a -INFINITY location constraint for the resource on the node where it was initially running. Clear the constraint.
      • Click the Ban button. Verify that there is a -INFINITY location constraint for the resource on the node where it was initially running. Clear the constraint.
      • Click the Move button and specify a target node. Verify that there is an INFINITY constraint for the resource on the target node.
      • Click the Ban button and specify a target node. Verify that there is a -INFINITY constraint for the resource on the target node.

      --------------------

      7. Is there already an existing RFE upstream or in Red Hat Bugzilla?

      No

      --------------------

      8. Does the customer have any specific timeline dependencies and which release would they like to target (i.e. RHEL5, RHEL6)?

      No; "the sooner it is the better"

      --------------------

      9. Is the sales team involved in this request and do they have any additional input?

      No

      --------------------

      10. List any affected packages or components.

      pcs

      --------------------

      11. Would the customer be able to assist in testing this functionality if implemented?

      Yes
