Yes, sorry it was not really understandable. RAID 0 is stripping, it increase space and throughput. You can have nearly the same using LVM2, and LVM2 is really more powerful. So I think you should build another software RAID-1 with your two spare drives, put both RAID-1 in a Volume Group using LVM2, and create your partitions in it (using strip option if you need to increase performances). You will increase available size (2x) without increasing risk (software RAID-5). If you need more space in a few years, you can add another RAID-1, or replace one of them by a bigger one in your Volume Group. You can then extend partitions. This is not possible using RAID-0/RAID-10. -- Sébastien Koechlin ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
