<p class="MsoNormal">Related to instance being stuck in “image_snapshot” for extended period of time, it is easy to “recover” the instance (script uses pre-defined timeout to “guess” that snapshot has hung and will never complete) and bring it back to “usable”
state, I also the *<b>inform the user that their snapshot attempt has failed</b>*.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The image goes thru the following statuses during normal case : Queued -> Saving -> Active -> Deleted
<o:p></o:p></p>
<p class="MsoNormal">If the upload of the image fails checksum verification, status is marked as “killed” (Using _<i>safe</i>_kill() - a private method)<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Neither of “killed” and “deleted” instances are shown to the user either in Dashboard (Horizon) or “nova image-list”<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><b>So when “recovering” hung snapshot – what status should be set for the image ? (Such that user knows of the error)<o:p></o:p></b></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’m thinking that we need to either Introduce a new status like “error”
<o:p></o:p></p>
