Subject: Kilo - Glance checksum error question
To: "chrishull42 at gmail.com" <chrishull42 at gmail.com>


Hello Stackers;

I’ve been working with my manually installed (according to the Openstack
Kilo instructions) Kilo installation.  It’s all in one box, i7, plenty of
RAM and disk.   Everything seems to work except “large”glance images.
I’ve posted about this before and now have had some time to experiment a
little.
It looks like Glance is storing a bogus check sum in the database.   I
think this because when I download the image, I consistently get a
different checksum.  If Glance were experiencing noise, I’d epxect to get
different checksums back out, but they all seem to be the same.

How or why would glance record an incorrect checksum?

Thanks;
-Chris
