Comment 6 for bug 1941062

The described workaround (adding a nova section to the cinder.conf) seems to work in V as well. After adding it the in-use volume can be migrated to a different volume type now. One difference between V and W I noticed was that in V I see two volumes with the same name (but a different UUID, of course) during the retype process while in W I see only one volume at all times. So I assume that W handles the retype differently and it doesn't require a nova section.
