Hi all,
I have setup a CentOS6.3 x86_64 host to act as a nfs server. According to RHEL6 docs, portmap is not needed when you use NFSv4, but in my host I need to start rpcbind service to make NFSv4 works.
My /etc/sysconfig/nfs
# # Define which protocol versions mountd # will advertise. The values are "no" or "yes" # with yes being the default MOUNTD_NFS_V2="no" MOUNTD_NFS_V3="no" # # # Path to remote quota server.

The default is port # is random #STATD_OUTGOING_PORT=2020 # Specify callout program #STATD_HA_CALLOUT="/usr/local/bin/foo" # # # Optional arguments passed to rpc.idmapd.

And rpcinfo -p:
