Comment 7 for bug 1405862

Dmitry B,

the problem it that cinder does not _show_ snapshots if volumes list or volume details is called. Cinder doesn't allow do delete volume if it has snapshot. It's a common behavior to not delete objects if it contains depended data. Volumes could be deleted only if all it's snapshots are deleted.

We can't fix it in MOS <7 because it requires API changes. It could be REST API or python-cinderclient API. In such cases our OpenStack will have different API with upstream.

I can't say that it is workaround, because it's a feature request, not bug. May be it's only UX issue.

you need to call 'cinder snapshot-list | grep <vol_id>' before volume delete and delete all volume's snapshots using 'cinder snapshot-delete <snapshot_id>' command
