[Gluster-users] Volume creation time?

[Jason Hilton]

Also, my OS is CentOS 7 and gluster is version 3.6.2, if that helps.

Yes, Gluster comes indeed with its own NFS-server. You should not start any NFS-services, Gluster takes care of starting them. The only service that you need to have running (or activated for systemd environments), is rpcbind.

Once your volume has been created and started, you should be able to see that there is a NFS-server running with this command:

    # gluster volume status

And, with 'showmount -e' the volme should be listed as an export.

Cheers,
Niels
