> During MS shutdown, all pending work items (op_it_work.step != 'Done') for it
> are picked up by other MS in cluster. The new MS then try to see for all
> pending work items, if the VMs are running or not and if not try to start
> them (using the same mechanism used to HA VMs). In case the investigators
> find out that VMs are still alive no action is needed. This completes the
> process for checking all pending work items.
> Looks like there is a bug in the code where the op_it_work.step is not marked
> as 'Done' in the above case thereby leaving the work items as pending always.
> As a result every time MS owning these work items is shutdown, the work items
> are picked up by another MS and the steps mentioned above gets repeated.
> Scenario where a pending work item may get created. If there is a failure to
> deploy VM then type and step gets set to 'Starting' and 'Release'
> respectively. Ideally if the operations ends gracefully then the step gets
> updated to 'Done'. But if there is an abrupt termination then it is possible
> that for some work items the step still remains in 'Release'. As a result of
> this the step never gets updated to 'Done' for these items and are always
> tried when a new MS takes over.
