The Bio Roll can be installed during the frontend installation step of your cluster (refer to section 1.2 of the Rocks usersguide). If this method is chosen, then the Bio Roll is added to a frontend installation in exactly the same manner as the required OS Roll. Specifically, after the OS Roll is added, the installer will once again ask if you have a Roll (see below). Select 'Yes' and insert the Bio Roll.
The Bio Roll can also be added to running frontend. Here's the procedure for an x86_64 cluster (for an i386 cluster, substitute x86_64 with i386).
# cd /tmp # wget http://www.rocksclusters.org/ftp-site/pub/rocks/extras/4.2/x86_64/bio-4.2-0.x86_64.disk1.iso # mount -o loop bio-4.2-0.x86_64.disk1.iso /mnt/cdrom # cd /home/install # rocks-dist --install copyroll # umount /mnt/cdrom # rocks-dist dist # kroll bio > /tmp/bio-install.sh # sh /tmp/bio-install.sh |
Now install your compute nodes (or re-install your compute nodes if you added the roll to a running system).
