My setup is as follows: - I have four 500GB disks. Each disk is split into a 5GB partition, and a 495GB partition. - The four 5GB partitions are in a RAID-5 array, md0. CentOS is installed on this 15GB partition. - The four 495GB partiions are in a RAID-5 array, md1. This partition holds my user data. However, I have decided I no longer wish to two arrays across the disks. I've added a fifth disk on which I have installed the OS without RAID, meaning the old md0 is currently unused. Can I simply remove the four 5GB partitions, and resize the four 495GB partitions to fill the entire disk? Will this break anything? Before anybody tells me off for having the OS on a non-RAID disk, this is a home server and therefore high availability is not an issue. But keeping my data safe against disk failures is important to me. Cheers, Jonathan ---------------------- Jonathan Gazeley ResNet | Wireless Team Information Services ----------------------
