Each Gluster server that is going to also act as an NFS server (or Samba) has
to mount the volume using the Gluster client:
There is no mounting taking place to export GlusterFS through NFS. That
NFS server is a GlusterFS client, is correct but it is also a
translator. That means any translation from NFS ops to GlusterFS ops
happens internally in the Gluster NFS server process, without having to
go through a mount point.

For example, on my two GlusterFS servers I have the following:
LABEL=brick01-01 /export/nas-01/brick01 ext4 defaults,_netdev
0 2
LABEL=brick01-02 /export/nas-01/brick02 ext4 defaults,_netdev
0 2
...bricks 3-8
LABEL=brick01-09 /export/nas-01/brick09 ext4 defaults,_netdev
0 2
localhost:/dev-storage /develop glusterfs defaults,_netdev
0 0
LABEL=brick02-01 /export/nas-02/brick01 ext4 defaults,_netdev
0 2
LABEL=brick02-02 /export/nas-02/brick02 ext4 defaults,_netdev
0 2
...bricks 3-8
LABEL=brick02-09 /export/nas-02/brick09 ext4 defaults,_netdev
0 2
localhost:/dev-storage /develop glusterfs defaults,_netdev
0 0
And then "/usr/sbin/showmount -e nas-01" and "/usr/sbin/showmount -e nas-02" both show
the "/dev-storage *" export.
Also verify your firewalls have the appropriate ports open on all servers. For
example on CentOS 5 for 2 servers with 18 bricks and 1 volume:
# GlusterFS
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 111 -j ACCEPT
-A RH-Firewall-1-INPUT -m state --state NEW -m udp -p udp --dport 111 -j ACCEPT
# GlsuterFS 24007, 24008 plus 1 port per brick across all volumes, 18 bricks in
this case
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 24007:24026
-j ACCEPT
# Gluster port 38465 and NFS for 2 Gluster servers, 1 port per server
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 38465:38468
-j ACCEPT
# End GlusterFS

Actually, showmount didn't work.
We get permission denied. Even after playing with the auth.allowed flag.
That's an indication that the gNFS server is not running.
I would recommend you review the FAQ and some of the recent posts on
the list, as there have been a couple threads discussing numerous
NFS-related issues and their solutions. I've collected them for you
here for your convenience:
