You need to make sure that there are no NFS services from the OS
running as they conflict with Gluster/NFS. I do not know what
"nfs-common" starts or sets-up, but I guess you need to disable this
service and restart all Gluster/NFS processes. "rpcbind" is required,
Gluster/NFS will only register itself there when no other NFS-service
occupies the slots.

Note that there can only be one NFS implementation active on a server.
This counts for both NFS-client and NFS-server, some of the services
(like NSM/NLM) are shared and conflict with each other. When Gluster/NFS
is enabled on the server, the server should ideally not mount any
exports over NFS (and te other way around).

HTH,
