OK. So I should make 2 partitions on each disk. One small one for /boot which can be RAID1 with 2 spares. The other partition would be as previously described. 2 Raid1 pairs striped into one RAID10 Drive. > Or is there a better way? > > Can you make a RAID partition for RAID0 over previously > prepared RAID1 partition?

Actually it would be a 640GB drive because RAID 0 usage space on both disks. > > > Thanks, > > Krsnendu dasa > > > > > > On 26/08/07, Scott Balneaves <[EMAIL PROTECTED]> wrote: > > On Sat, Aug 25, 2007 at 12:35:38PM -0700, Joe Rowe wrote: > > > > > > Like myself, > > > More and more people are using Edubuntu or Ubuntu > > > servers or critical workstations with inadequate plans for > > Disk failure. > > > > > > > > > Anyone, > > > Please reply if you have done software RAID on Ubuntu/Edubuntu > > > and you are good at documenting steps by step tips. > > > > I've done software raid for years and years.
