[Gluster-users] Configuring Ganesha and gluster on separate nodes?

[Surya K Ghatty]

Hi:

I am trying to understand if it is technically feasible to have gluster
nodes on one machine, and export a volume from one of these nodes using a
nfs-ganesha server installed on a totally different machine? I tried the
below and showmount -e does not show my volume exported. Any suggestions
will be appreciated.

1. Here is my configuration:

 Gluster nodes: glusterA and glusterB on individual bare metals - both in
Trusted pool, with volume gvol0 up and running.
Ganesha node: on bare metal ganeshaA.

2. my ganesha.conf looks like this with IP address of glusterA in the FSAL.

 FSAL {
                Name = GLUSTER;

                # IP of one of the nodes in the trusted pool
                hostname = "WW.ZZ.XX.YY"  --> IP address of GlusterA.

                # Volume name. Eg: "test_volume"
                volume = "gvol0";
        }

3. I disabled nfs on gvol0. As you can see, nfs.disable is set to on.

[root at glusterA ~]# gluster vol info

Volume Name: gvol0
Type: Distribute
Volume ID: 16015bcc-1d17-4ef1-bb8b-01b7fdf6efa0
Status: Started
Number of Bricks: 1
Transport-type: tcp
Bricks:
Brick1: glusterA:/data/brick0/gvol0
Options Reconfigured:
nfs.disable: on
nfs.export-volumes: off
features.quota-deem-statfs: on
features.inode-quota: on
features.quota: on
performance.readdir-ahead: on

4. I then ran ganesha.nfsd -f /etc/ganesha/ganesha.conf
-L /var/log/ganesha.log -N NIV_FULL_DEBUG
Ganesha server was put in grace, no errors.

5. [root at ganeshaA glusterfs]# showmount -e
Export list for ganeshaA:
<empty>

Any suggestions on what I am missing?
