Hi, These instructions are brief, and 7.2 tested, but should work much the same way with 8 and 8.1. your question was about mirroring which is slightly slower then a single drive, but you will have data redundency (same info on two drives.) RAID0 -> splits data on to two drives for inproved performance. RAID1 -> Mirror data on more then one drive to create redundancy. (slower) RAID2 onwards, mixes mirroring and striping to give benefits of both in different mixes, usually needs 3 or more drives. I will concentraite on the first two RAID inplimentations. 1. Hook both your drives up. 2. Boot from MDK CDROM and select Expert install. 3. Choose Diskdrake when you get asked. 4. Create a 20MB partition of EXT2 on drive1, and point it to /boot. (boot is tiny and doesn't benefit from Raid.) 5. Find the area on disk one that you want to be the first Raid-0 array, and select "Add to Raid" It will be called md0 by default (md means multiple disk) you can then set what level of RAID you want. leave the chunksize of 64k. (its the size of strips accross the drives. 64k is a good default for large and small files.) 6. Select equal size partition on drive 2. and "Add to Raid" select md0 for target. 7. Do the same on both drives with the swap, (ie create equal swap partitions on each drive creating md1 for both.. 8. Click the RAID tab in diskdrake click on the RAID arrays free space (md0) and choose REISERFS, (or whatever FS you want.) then do the same for md1 except select linux Swap.. 9. Set the mount point for md0 to / (ie the root partition). I think the swap will be allocated automatically. 10 Install linux as per normal from that point, MDK should do the rest for you. Thats it, when finished you will have your linux box booting in software RAID, if you chose mirroring it will be a tiny bit slower then one drive (because its writing data twice), but if you chose striping it will be probably 10-60% faster then a single drive. Hope that helps someone, I have written that as generic as I can in the hope that it will help more then one person..... rgds Frank Frank Hauptle Network Payment Solutions.
