Integrating ganesha NFS with gluster

[wkihara]

Hello

I am on these version of the software and struggling to get the setup working.
glusterfs-9.3-2
nfs-ganesha-3.5-3

I have setup a basic gluster volume:
[root@ganesh-01 ~]# gluster volume info william2

Volume Name: william2
Type: Distribute
Volume ID: be388d3d-d834-41db-b4d1-f7df338dfc7f
Status: Started
Snapshot Count: 0
Number of Bricks: 1
Transport-type: tcp
Bricks:
Brick1: ganesh-01.eng.example.com:/export/eng/gluster
Options Reconfigured:
storage.fips-mode-rchecksum: on
transport.address-family: inet
nfs.disable: on
[root@ganesh-01 ~]#

I am using this basic ganesha configuration. I actually copied it online from a discussion where the user said it worked for him

[root@ganesh-01 ~]# cat /etc/ganesha/ganesha.conf
EXPORT
{
# Export Id (mandatory, each EXPORT must have a unique Export_Id)
Export_Id = 1;

    # Exported path (mandatory)
    Path = /gjsmedia;

    # Pseudo Path (required for NFS v4)
    Pseudo = /gjsmedia;

    # Required for access (default is None)
    # Could use CLIENT blocks instead
    Access_Type = RW;
    Squash = No_root_squash;
    Disable_ACL = TRUE;
    Protocols = 3,4;
    Transports = UDP,TCP;
    SecType = sys;

    # Exporting FSAL
    FSAL {
            Name = GLUSTER ;
            Hostname = 192.168.20.207 ;
            Volume = william2 ;
    }
    CLIENT
    {
            # This block is actually meaningless since 192.168.0.22 will
            # match the network address in the second CLIENT block.
            Clients = 10.0.20.0/24;
            Squash = None;
            Access_Type = RW;
    }

}

When I restart ganesha after putting the above configuration in place, I am seeing this error in the logs. (Ganesha logs)

What could I be missing to trigger this error? I have tried it couple of permutations of this configuration and all genarating this error when I attempt to run it over gluster.

William

/var/log/gluster/gfapi.log should give more details on why volume initialization failed.
