Comment 26 for bug 1371677

One more thing:

looking at the orriginal patch (http://logs.openstack.org/10/110110/40/check/check-tempest-dsvm-postgres-full/4cd8a81/logs/screen-n-cpu.txt.gz#_2014-09-19_10_24_31_404) and matts fix here https://review.openstack.org/122874 - we should never be hitting that exception in the gate because: this exception should never happen in _get_instance_disk_info UNLESS we are running LVM backed instances - which afaiu never happens in the gate.

So there seems to be another bug here which we should report.
