Configuring NFS-Ganesha for Rados Gateway in Red Hat Ceph Storage 2.x, fails to export the RGW buckets.

The Rados Gateway logs show the following messages:

The service was restarted with:

# systemctl status nfs-ganesha.service

Resolución Configured NFS-Ganesha in /etc/ganesha/ganesha.conf as following:

EXPORT {
        Export_ID = 100;
        Path = "/";
        Pseudo = "/";
        Access_Type = RW;
        SecType = "sys";
        NFS_Protocols = 4;
        Transport_Protocols = TCP;
        Squash = No_Root_Squash;

        FSAL {
                Name = RGW;
                User_Id = s3user1;
                Access_Key_Id ="<ACCESS_KEY>";
                Secret_Access_Key = "<SECRET_KEY";
        }
}

RGW {
    name = "client.rgw.vm250-217";
    ceph_conf = "/etc/ceph/ceph.conf";
    init_args = "--{arg}={arg-value}";
}

Started rpcbind via systemd and ganesha using the binary and configuration file.

# systemctl start rpcbind

# /usr/bin/ganesha.nfsd -f /etc/ganesha/ganesha.conf

Verified if the process is running fine.

# ps -aux | grep -i ganesha
root     18347  0.0  0.0 107904   652 pts/2    S+   01:04   0:00 tailf /var/log/ganesha.log

Confirm if the export is showing up properly

# showmount -e

Export list for <NFS-server>:
/ (everyone)

The logs at /var/log/messages showed the following, which ensured the process initiating properly.
