The reason people stripe is performance. The performance gain is by having more disk heads working. If you stripe a single disk (or 2 if mirrored), it will thrash! This will hurt/kill performance. Just mirror. Oh, you could do it if you want. It will work. Create a mirror (RAID1) with each pair of chunks, 6 mirrors total (with your example). Then stripe the mirrors (RAID0). -----Original Message----- From: linux-raid-owner@vger.kernel.org [mailto:linux-raid-owner@vger.kernel.org] On Behalf Of Keld Jørn Simonsen Sent: Saturday, January 31, 2004 2:53 PM To: linux-raid@vger.kernel.org Subject: striping and mirroring with only two disks Hi! Is it possible to both do striping and mirroring if you only have 2 disks? I was thinking of having the chunks organized on each disk so that striping reads and writes could be done. Eg. by having disk1: chunk0 chunk2 chunk4 ...... chunk1 chunk3 chunk5 disk2: chunk1 chunk3 chunk5 ...... chunk0 chunk2 chunk4 Would such a layout of chunks allow for striped reading and writing?
