These messages suggest that the portmapper/rpcbind already has a NLM
service registered. Gluster/NFS tries to be friendly to other services
and does not kick them out. Sometimes it happens that there is a stale
registration left behind... One cause was a change in the rpcbind
systemd unit, see https://bugzilla.redhat.com/1181779 for more details.
If you are on RHEL-7 or CentOS-7, this solution is known to work:
# sed "s/ -w//" /usr/lib/systemd/system/rpcbind.service > \
/etc/systemd/system/rpcbind.service
# systemctl daemon-reload
# systemctl restart rpcbind
# systemctl restart glusterd
Alternatively you can check with 'rpcinfo -p' which ports are registered
at the portmapper, and check with 'netstat' or 'ss' if there is a
process listening on these ports. You can manually unregister the
(stale) ports with 'rpcinfo -d 100021 4' (NLM, version 4).
