Sorry if this has been answered but after several days trying to narrow 
down to a dristributed filesystem, I am still unsure what to pick. I 
have narrowed it down to two: OpenAFS, and GFS.

Here is what I need:
1) Automatic data replication to multiple computers each with a drive 
dedicated to the OpenAFS volume. If one computer goes down, the data is 
still available from another computer.
   1a)  I plan on having 10 to 15 computers exporting one 400-500GB 
drive..How many drives/computers can I lose without jeopardizing the 
OpenAFS volume?
    2a) What happens to the OpenAFS system if I have to bring all the 
computers down, one by one?
2) Expandable. Can I add another 400-500GB drive to a new computer and 
add it to an existing OpenAFS volume?
3) Does OpenAFS need RAID for redundancy or is it taken care of at the 
filesystem layer?
4) Is there a 2GB file limitation? (I have read conflicting reports)
