NFS Consists of the following:
#/etc/exports contains all the NFS shares
#exportfs -r is used to synchronize nfsd in memory with the /etc/exports file
#Use exportfs -v to see which shares nfsd is currently exporting
/etc/rc.d/init.d/nfslock - which has 2 parts
/etc/rc.d/init.d/nfs - which has 3 parts
At bare minimum you need to have portmap (or portmapper),
mountd (or rpc.mountd), and nfsd (or rpc.nfsd) running;
otherwise NFS isn't running.
#Sample nfs /etc/exports file:
#Above we have two entries, one for everyone, and one
for the adminsvr machine.
