No, with RAID1 (mirroring) I would only have half usable ... here I'm trying to use RAID5 which means, (as a rough rule of thumb), I should have (N-1)x(size of disk) for N disks, so for six 500GB disks I should have (6-1)x500=2500GB usable.
Noting that that is very rough as a 500GB disk is only ~467GB usable anyway due to the way the manafacturers define disk sizes. Of course I could be wrong here but I normally don't expect to see a disk in the spare state in a normal RAID5 array, (but all the arrays I have seen using Linux Software RAID up to now have had a maximum of 4 disks and this has 6) Tim On 12/2/07, Philippe Landau <[EMAIL PROTECTED]> wrote: > Tim Hempstead wrote: > > Hi, I've been spending the afternoon upgrading my home server and I'm > > having an issue with creating a RAID5 array to hold the data.
