The other day I tried a CentOS 4.2 install on two IDE drives. My goal was to mirror them (software raid 1) and put them in an LVM so that I might, in future, add two more drives and add them to the existing mirror. 1) Is this possible? 2) If so, how? I could not figure it out despite trying what seemed like every combination of options in disk druid. I succeeded in getting a RAID 1, but not in putting a RAID inside a logical volume. Thanks, Matt
