[Gluster-users] mount failing client to gluster cluster.

[Thing]

Hi,

On a debian 9 client,

========
root at kvm01:/var/lib/libvirt# dpkg -l glusterfs-client
8><---
ii  glusterfs-client                  3.8.8-1               amd64
       clustered file-system (client package)
root at kvm01:/var/lib/libvirt#
=======

I am trying to to do a mount to a Centos 7 gluster setup,

=======
[root at glustep1 libvirt]# rpm -q glusterfs
glusterfs-4.0.2-1.el7.x86_64
[root at glustep1 libvirt]#
=======

mount -t glusterfs glusterp1.graywitch.co.nz:/gv0/kvm01/images
/var/lib/libvirt/images


the logs are telling me,
=========

though,

mount -t glusterfs glusterp1.graywitch.co.nz:/gv0 /isos

works fine.

also, I can mount the sub-directory fine on the gluster cluster itself,
