Open Stack

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.
