Hi, Well, when we bought the machines they just came with the 40GB HD and so when we use it as nodes the HDs become kinda useless. So I was just thinking of a more economic way to utilize them rather than having to add another HD on the master node. I was also thinking of exporting it to all nodes (via NFS) so al nodes will see /home /home2 /home3 etc. Might be kinda messy.. but .. :) RDB > Cheers, > > Bernard > > Reuben D.
