HOWTO setup NFS for the online computers

This page was written to document how the gluon02-gluon05 machines were configured to mount a directory from gluon02 via NFS. The intent is for gluon02 to serve as a temporary file server for the gluon machines until the dedicated server is delivered and installed.

The gluon machines are running Red Hat Enterprise Linux 6.3

Configuring NFS server

• Create a directory to that you wish to export:

mkdir /group/gluoncfs

• Edit the file /etc/exports

  This should specify a range a range of IP addresses, but for now, each of the 4 machines in the counting house are listed individually. (Yes, it is unnecessary to list gluon2 since it is the host machine, but I did it anyway)

  The lines look like this:

/group/gluoncfs   129.57.172.11(rw,no_root_squash,async)
/group/gluoncfs   129.57.172.12(rw,no_root_squash,async)
/group/gluoncfs   129.57.172.13(rw,no_root_squash,async)
/group/gluoncfs   129.57.172.14(rw,no_root_squash,async)

• Fire up the nfs server:

/etc/init.d/nfs start

• Enable the NFS service so it starts automatically on reboot
  1. Go to System->Administration->Services.
  2. When the window finally gives you control, select "nfs" and hit the green "Enable" button
  3. Note that I did not reboot gluon02 after doing doing this and just assume it will work

Configuring NFS Clients

• Edit the file /etc/fstab to include a line like this:

gluon02:/group/gluoncfs  /group/gluoncfs  nfs tcp 0 0

• Mount the NFS volume

 mount /group/gluoncfs

• This should auto-mount on reboot since it is in /etc/fstab, but only if gluon02 is already up and running. If it is not, there may be some sort of delay on startup while it times out. This was not tested.
