I'm looking for a solution that would provide large amounts of data
storage and would be able to grow exponentially. I am a network
administrator for a school, like most schools right now budgets are
tight and our data storage needs are growing. I am looking to make a
giant raid5 out of retired machines. I was looking at the open-afs
project to create a network data storage cloud. As machines are retired
they would be added to the data storage cloud and all data would be
split across several machines like raid5. Is this or can this easily be
implemented using open-afs?

In my opinion the best thing afs offers to anyone regardless of your
data needs (sizewise) is the flexibility the system admin has over the
data. With afs you can move a volume from server a to server b with one
command. During this time the user is completely unaware. The user can
read and write to the volume while the operation is in progress.
So if you need to reboot a server or otherwise take it off line you can
empty the file server and then do with it what you will. The quota of
the volume can be increased or decreased as well.
I would suggest giving some thought to your data storage. It isn't much
use to make a 30 gig volume if you cant move it to another server with
30 gig space. So similar sized storage media are a good idea.
