shared storage: Prevent mounting shared storage from non-trusted client
gluster shared storage is a volume used for internal storage for various features including ganesha, geo-rep, snapshot. So this volume should not be exposed to the client, as it is a special volume for internal use. This fix wont't generate non trusted volfile for shared storage volume. Change-Id: I8ffe30ae99ec05196d75466210b84db311611a4c fixes: bz#1568844 BUG: 1568844 Signed-off-by: Mohammed Rafi KC <rkavunga@redhat.com>
