[Openstack-operators] Storage backend for glance

Yup, it's definitely possible. All Glance nodes will need to share the same
database as well as the same file system. Common ways of sharing the file
system are to mount /var/lib/glance/images either from NFS (like you
mentioned) or Gluster.

I've done both in the past with no issues. The usual caveats with shared
file systems apply: file permissions, ownership, and such. Other than that,
you shouldn't have any problems.

Hope that helps,
Joe
