Glance interoperable image import requires a consistent filesystem across the controller nodes. One option is to use an NFS share for this.
This needs to be documented properly in our documentation.
@Kim: could you take a look at this? I think Pranali could help you.
Yes, I believe this is related to https://bugzilla.redhat.com/show_bug.cgi?id=1300585 . Erno know all the details :)
Changing the component to documentation, to make sure that the BZ has visibility to the doc team.
