I've got both glance and nova backed by NFS. Haven't put up cinder yet, but that will also be NFS backed. I just have very limited storage on the compute hosts, basically just enough for the operating system; this is just a small but permanent lab deployment. Good to hear that Glance will Just Work. :) Thanks! Thanks, Curtis. > > On Wed, Oct 12, 2016 at 11:18 AM, Curtis <serverasc...@gmail.com> wrote: >> >> On Wed, Oct 12, 2016 at 11:58 AM, Kris G.
