28 | # @JobStatus: | |
29 | # | |
30 | # Indicates the present state of a given job in its lifetime. | |
31 | # | |
32 | # @undefined: Erroneous, default state. Should not ever be visible. | |
33 | # | |
34 | # @created: The job has been created, but not yet started. | |
35 | # | |
36 | # @running: The job is currently running. | |
37 | # | |
38 | # @paused: The job is running, but paused. The pause may be requested by | |
39 | # either the QMP user or by internal processes. | |
40 | # | |
41 | # @ready: The job is running, but is ready for the user to signal completion. | |
42 | # This is used for long-running jobs like mirror that are designed to | |
43 | # run indefinitely. | |
44 | # | |
45 | # @standby: The job is ready, but paused. This is nearly identical to @paused. | |
46 | # The job may return to @ready or otherwise be canceled. | |
47 | # | |
48 | # @waiting: The job is waiting for other jobs in the transaction to converge | |
49 | # to the waiting state. This status will likely not be visible for | |
50 | # the last job in a transaction. | |
51 | # | |
52 | # @pending: The job has finished its work, but has finalization steps that it | |
c5b09f3f JS |
53 | # needs to make prior to completing. These changes will require |
54 | # manual intervention via @job-finalize if auto-finalize was set to | |
55 | # false. These pending changes may still fail. | |
bf42508f KW |
56 | # |
57 | # @aborting: The job is in the process of being aborted, and will finish with | |
58 | # an error. The job will afterwards report that it is @concluded. | |
59 | # This status may not be visible to the management process. | |
60 | # | |
c5b09f3f JS |
61 | # @concluded: The job has finished all work. If auto-dismiss was set to false, |
62 | # the job will remain in the query list until it is dismissed via | |
63 | # @job-dismiss. | |
bf42508f KW |
64 | # |
65 | # @null: The job is in the process of being dismantled. This state should not | |
66 | # ever be visible externally. | |
67 | # | |
68 | # Since: 2.12 | |
