Hi Nick,
Thanks for the reply, looks like we could be hitting something similar.
We are running Ceph Jewel packages on the Glance node.
Thanks for the links to the bug reports.
Regards,

Hi Grant.
Could be unrelated but I'm throwing it out there anyway as we had
similar 'weirdness' with Glance recently... If you're running the
Ceph Jewel or Hammer packages on your Glance node then you might be
running into this bug, in which image.stat() calls in librbdpy fail
intermittently:
http://tracker.ceph.com/issues/17310
There's a corresponding bug report on Launchpad for the Ubuntu Ceph
package that has some more detail:
https://bugs.launchpad.net/ubuntu/+source/ceph/+bug/1625489
Cheers.

Hi All,
Not sure if anyone has come across this yet. Yesterday we started
to try to upload some images to our stack and they were failing
with the following error when trying via command line:
Error finding address for

In the Glance logs at the same time we see this:

Interestingly, when you delete the failed image you get this in
the glance logs:
2017-01-31 10:23:16.188 2099 INFO eventlet.wsgi.server
[req-c2191fe1-64de-4252-b4a2-e84643dbed4c

It seems to be using V1 to try and upload and V2 to remove? -
However the image doesn't actually get deleted because it remains
in ceph:
rbd -p images ls | grep e90a4626-4781-4b53-8914-85ff2129f777
e90a4626-4781-4b53-8914-85ff2129f777
It is almost as if, the image uploads and is then forgotten about.
Our compute nodes are also ceph backed and they are working
absolutely fine, it is just Glance and ceph has all of a sudden
stopped working. Just wondered if anyone had any ideas?
