Middle Earth: shared disk

To stop copying everything all the time I needed a shared disk. Parallel Virtual File system was my parallel FS of choice but also I needed a quick and not so fast and reliable filesystem for tests. For that, I chose NFS. Later I can install PVFS if I need to.

Well, install NFS on Ubuntu is VERY simple!


Install the packages:

sudo apt-get install nfs-user-server nfs-common

Then, edit the /etc/exports file in the server:

/scratch/global frodo(rw) sam(rw) merry(rw) pippin(rw)

Create the directory, with permission to the group users:

mkdir /scratch/global/
chmod g+ws /scratch/global/
chgrp users /scratch/global/

and start the service:

sudo /etc/init.d/nfs-user-server restart


Install the package:

sudo apt-get install nfs-common

Edit the /etc/fstab and add the mount point:

gandalf:/scratch/global /scratch/global nfs rw 0 0

Create the directory and mount it:

sudo mkdir /scratch/global/
sudo mount /scratch/global/

That’s just it… really.
