===Adding a file server to Wynton===
Connect an open network port on host to Wynton's network.  Ask JL for IP-address and ports to connect to in BH101.  
Create network interface in /etc/sysconfig/network-scripts for new interface.  Populate with the following:
 
'''/etc/sysconfig/network-scripts/ifcfg-<interface name>'''
 TYPE=Ethernet
 DEVICE=<interface name>
 BOOTPROTO=static
 HWADDR=<MAC Address> 
 ONBOOT=yes
 IPADDR=<Wynton IP>
 NETMASK=255.255.255.0
 DHCP_HOSTNAME=<wynton network hostname>.wynton.ucsf.edu
 HOSTNAME=<wynton network hostname>.wynton.ucsf.edu

Create a static route to wynton

'''/etc/sysconfig/network-scripts/route-<interface name>'''
 172.26.0.0/16 via 172.26.28.1 dev <interface name> 

See lamed for example.

Edit /etc/exports.  Backup the configuration just in case of messups.  Export the NFS files to 172.26.0.0/16 with (rw,sync,fsid=<insert fsid>).
Issue command: 
 exportfs -a

===Issues===
CentOS 6 NFS servers are showing user/group ownerships as nobody:nobody.  This problem doesn't happen on the CentOS 7 machines.  They are mounted NFSv4.0.  

This is due to /sys/module/nfsd/parameters/nfs4_disable_idmapping.  To address: 

On the NFS Server exporting to Wynton: 
  echo 'Y' > /sys/module/nfsd/parameters/nfs4_disable_idmapping 
  exportfs -a
