Description of problem: Continued work on #1627997. Implementing an option to trigger the finished tasks cleanup via UI.
Verification flow for QE - mostly copied from https://bugzilla.redhat.com/show_bug.cgi?id=1627997, only step #11 is different: Please try the following: 1) Run the engine, add a host and a Storage Domain. 2) Open the CLI terminal to the host via ssh. 3) Execute on the host the following command: $ vdsm-client Host getAllTasksStatuses You should probably see an empty response, i.e., "{}". That's good, now you can continue. 4) Start adding a new disk: Storage --> Disks --> New. Don't press "OK" just yet. The following steps need to be done fast, I used breakpoints to stop the flow where I need it, so I was more lucky :) 5) Press "OK" to finish adding a disk. 6) Go to the host CLI and see the response: $ vdsm-client Host getAllTasksStatuses It should be something like that: { "1dc4d885-577a-4b6a-b01f-e682602a907c": { "code": 0, "message": "1 jobs completed successfully", "taskID": "1dc4d885-577a-4b6a-b01f-e682602a907c", "taskResult": "success", "taskState": "finished" } } 7) Kill the engine as fast as possible: CTRL+C. 8) After the engine stops verify that there still a finished task on the host (same command as mentioned above), that is you don't receive an empty result "{}". If that doesn't happen, try not to execute step #6 in order to save time, simply press "OK" and kill engine after 1 second or faster. 9) Start the engine, wait until it's up. 10) Verify (again) that there still a finished task on the host, as in step #6. 11) Go to the engine UI: Compute --> Data Centers. 11a) Select the relevant Data Center (where host with SPM runs) and via the menu you can "Cleanup Finished Tasks". 11b) You can also run flows with a multiple selection of Data Centers (the "Cleanup Finished Tasks" commands runs in parallel on all of them). Worth checking. 11c) The "Cleanup Finished Tasks" menu is allowed only if *all* the selected Data Centers are active. If at least one is not active the menu is greyed-out/inactive. Also worth checking :) 12) Verify (using the above command) that there are NO finished tasks on the host (that means all were cleared by the command that you executed from the UI menu) and you receive an empty response as it was at the beginning: "{}".
