Liberation Instructions

These instructions will describe the process of "liberating" the BCCD onto a LittleFe. This replicates the BCCD cluster environment in a stable form on a harddrive.

1. Download and burn the latest BCCD from the BCCD download page.
2. Boot lf0 with the new BCCD CD.
3. Login as root
4. run list-packages and install the following packages:
   • liberation
   • nfs
5. install the tftp package by running the following commands:
   • cd /usr/local/
   • wget http://cluster.earlham.edu/~lemanal/lib-packs/tftp.tar.gz
   • tar -zxvf ./tftp.tar.gz
6. begin the liberation process: liberate hda . If you are absolutely sure you have nothing left on your original harddrive enter 'y' to reformat the drive and install the new BCCD version.
7. Once this process is complete, remove the CD and reboot the machine. reboot

Now, you should be running a fresh BCCD from the harddrive. The next steps will prepare the BCCD installation as a login node for this LittleFe.

1. Insert the BCCD from which you liberated
2. run: /usr/local/sbin/prepareserver
3. run: discoverhosts.sh
   • Boot up a node and wait for discoverhosts.sh to recognize the new host.
   • Once it is recognized shutdown the new node and start up the next node.
   • Repeat this until every node except the login node has been recognized as a new node.
4. run: fbsetup.sh and choose your desired resolution mode. This change will require a reboot. The resolution can be changed later by running fbset (does not require rebooting after the initial fbsetup.sh run) or rerunning fbsetup.sh and rebooting.
5. Reboot lf0 shutdown -r now . Wait for it to boot. And then turn on the rest of the nodes and test the setup.
