The above line suggests that there already is a service registered at
portmapper for the NLM4 program/service. This happens when the kernel
module 'lockd' is loaded. The kernel NFS-client and NFS-server depend on
this, but unfortunately it conflicts with the Gluster/nfs server.
Could you verify that the module is loaded?
- use 'lsmod | grep lockd' to check the modules
- use 'rpcinfo | grep nlockmgr' to check the rpcbind registrations
Make sure that you do not mount any NFS exports on the Gluster server.
Unmount all NFS mounts.
You mentioned you are running CentOS-7, which is systemd based. You
should be able to stop any conflicting NFS services like this:
# systemctl stop nfs-lock.service
# systemctl stop nfs.target
# systemctl disable nfs.target
If all these services cleanup themselves, you should be able to start
the Gluster/nfs service:
# systemctl restart glusterd.service
In case some bits are still lingering around, it might be easier to
reboot after disabling the 'nfs.target'.

The 'portmap' service has been replaced with 'rpcbind' since RHEL-6.
They have the same functionality, 'rpcbind' just happens to be the newer
version.
Did you file a bug for this already? As Vijay mentions, this crash seems
to happen because the Gluster/nfs service fails to initialize correctly
and then fails to cleanup correctly. The cleanup should get fixed, and
we should also give an easier to understand error message.
