Description nalmond 2018-12-11 18:55:10 UTC
Description of problem:
When converting a large qcow2 image to upload to Ceph-backed cinder, the root disk of a controller can become full without warning.

Version-Release number of selected component (if applicable):


How reproducible:
Consistently with large images and limited disk space

Steps to Reproduce:
1. Deploy RHOSP 10 with Ceph
2. Attempt to create a cinder volume from a large qcow2 image
3.

Actual results:
The root disk does not have enough free space for the conversion to complete properly and the disk becomes full.

Expected results:
A check is performed on available disk space before beginning the conversion.

Additional info:
This was addressed upstream by https://bugs.launchpad.net/cinder/+bug/1653225 and https://review.openstack.org/#/c/415868/ and has already been included in OSP 11+. Can we backport this to OSP 10?
