After I create the volume (using "cinder create 1") and the volume has an "available" status, I create a backup of the volume using "cinder backup-create <volume>". After I do this, the volume stays stuck in a "backing-up" status, and the backup is stuck
in a "creating" status. I have left the VM up for over three days, and the statuses of both remain unchanged. I am assuming that a backup should take place fairly quickly, especially for a 1GB volume, so I think there must be an issue with my setup.<o:p></o:p></span></p></div><div><p class="MsoNormal" style="margin-left:36.0pt"><span style="font-size: 10.5pt; color: black; font-family: Calibri, sans-serif; "><o:p> </o:p></span></p></div><div><p class="MsoNormal" style="margin-left:36.0pt"><span style="font-size: 10.5pt; color: black; font-family: Calibri, sans-serif; ">For my devstack setup, I have the following in localrc (as per the instructions for Swift at <a href="http://devstack.org/localrc.html">http://devstack.org/localrc.html</a>).
