==================== NFS server
-------------------- /etc/exports
/usr/local   192.168.0.1(ro) 192.168.0.2(ro)
/home        192.168.0.1(rw) 192.168.0.2(rw)
-------------------- /etc/hosts.deny
portmap:ALL
lockd:ALL
mountd:ALL
rquotad:ALL
statd:ALL
-------------------- /etc/hosts.allow
portmap: 192.168.0.1 , 192.168.0.2

/usr/sbin/exportfs -o rw,sync *:/usr/local
/usr/sbin/exportfs -v

==================== RPC startup order
rpc.portmap
rpc.mountd, rpc.nfsd
rpc.statd, rpc.lockd (if necessary), and rpc.rquotad
====================
rpcinfo -p
======================================== Client
-------------------- /etc/fstab
# device             mountpoint  fs-type    options    dump fsckord
server.foo.com:/home  /mnt/home   nfs      rw,hard,intr  0     0
--------------------
mount server.foo.com:/home /home
==================== Block Size to Optimize Transfer Speeds
time dd if=/dev/zero of=/mnt/home/testfile bs=16k count=16384
time dd if=/mnt/home/testfile of=/dev/null bs=16k

RAID 1/0 for both write speed and redundancy; RAID 5 gives you good read speeds
but lousy write speeds.

==================== Status
nfsstat
==================== Automount
-------------------- auto.master
/auto   /etc/auto.misc  --timeout=60
-------------------- auto.misc
