Greetings List: I have two new machines with the x86_64 Cent OS DVD''s in them. Something that was not covered that I have found so far in the Quick Start Guide for Lustre was how I should partition. I have 6x1TB in each machine all connected through SATA II. I have read that it will look for any block device or partion to reformat. That being clear should I partition enough space say 100GB for the initial filesystem and leave the rest of the devices blank? Should I raid this 100GB root partition accross all five disks with raid 5 or mirror it on one other with raid 1? Suggestions? Ardently; Arden Wiebe
