I'm trying glusterfs on Ubuntu Saucy (frontend) and Ubuntu Trusty
(nodes). I've followed the documentation but something is not working.
Might be me missing something here.

It reports "0M" - AVAIL. The "system" and "default" datastores are mounted
glusterfs volume (so glusterfs does work on frontend/nodes).

If I try to import an image from marketplace I get the following error:

[ImageAllocate] Cannot determine Image SIZE. Datastore driver 'shared'
not available.
