<p class="MsoNoSpacing">Hi all.<o:p></o:p></p>
<p class="MsoNoSpacing"><o:p> </o:p></p>
<p class="MsoNoSpacing">I am working on bug 1503390. (status=None while delete is in progress<o:p></o:p></p>
<p class="MsoNoSpacing">) <o:p></o:p></p>
<p class="MsoNoSpacing"><o:p> </o:p></p>
<p class="MsoNoSpacing">I was doing analysis of problem and found that yes its there.<o:p></o:p></p>
<p class="MsoNoSpacing">I reproduced it.<o:p></o:p></p>
<p class="MsoNoSpacing"><o:p> </o:p></p>
<p class="MsoNoSpacing">Now the two solutions proposed..<o:p></o:p></p>
<p class="MsoNoSpacing">1)Either say the status as deleting for such snapshots ?<o:p></o:p></p>
<p class="MsoNoSpacing">2)lets not list such snapshots in list ..<o:p></o:p></p>
<p class="MsoNoSpacing"><o:p> </o:p></p>
<p class="MsoNoSpacing">I see that <o:p></o:p></p>
<p class="MsoNoSpacing">If we implement solution1 .. then it doesn’t work as …..<o:p></o:p></p>
<p class="MsoNoSpacing">we reach the same Situation of (snapshot present but snapshot_instance absent)
<o:p></o:p></p>
<p class="MsoNoSpacing">in two cases<o:p></o:p></p>
<p class="MsoNoSpacing">When snapshot is deleted and when snapshot is created …<o:p></o:p></p>
<p class="MsoNoSpacing"><o:p> </o:p></p>
<p class="MsoNoSpacing">Now if I set status as deleting(to be shown in list for snapshots with no snapshot_instances)
<o:p></o:p></p>
<p class="MsoNoSpacing">it will be a wrong information when we are creating the snapshot.<o:p></o:p></p>
<p class="MsoNoSpacing">And list function – can not differentiate state (snapshot present but snapshot_instance absent)
<o:p></o:p></p>
<p class="MsoNoSpacing">whether its due to creation or deletion. PCIIMW…<o:p></o:p></p>
<p class="MsoNoSpacing"><o:p> </o:p></p>
<p class="MsoNoSpacing"><o:p> </o:p></p>
<p class="MsoNoSpacing">Another way to do this is .. let create delete path set the status to a special state .
<o:p></o:p></p>
<p class="MsoNoSpacing">which if list operation obtains .. can understand how to interpret it …<o:p></o:p></p>
<p class="MsoNoSpacing">But setting status also is not possible as status resides in snapshot_instances table ..<o:p></o:p></p>
<p class="MsoNoSpacing">row for which is not created yet in create path .. we can not set staus …!!!<o:p></o:p></p>
<p class="MsoNoSpacing"><o:p> </o:p></p>
<p class="MsoNoSpacing"><o:p> </o:p></p>
<p class="MsoNormal"><span style="color:#1F497D">Do you think that <o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">STATUS_NEW = 'new'<o:p></o:p></span></p>

<p class="MsoNormal"><span style="color:#1F497D">STATUS_MANAGING = 'manage_starting'<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">STATUS_MANAGE_ERROR = 'manage_error'<o:p></o:p></span></p>

<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Do you think that setting state as
<b><u>some neutral state like state_inactive ..<o:p></o:p></u></b></span></p>
<p class="MsoNormal"><span style="color:#1F497D">will help? <o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">it will be same in both creation and deletion path ?<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNoSpacing"><o:p> </o:p></p>
<p class="MsoNoSpacing">so should we go with 2<sup>nd</sup> solution ? lets not show such shares in list ?<o:p></o:p></p>
<p class="MsoNoSpacing"><o:p> </o:p></p>
<p class="MsoNoSpacing"><o:p> </o:p></p>
<p class="MsoNoSpacing">Thanks<o:p></o:p></p>
