I am in the process of setting up a new Debian 5.0 Lenny based VMware 2.0 server and will follow your most excellent tutorial, however.... Have had no end of trouble trying to install RAID 1 [Mirroring] with two 120Gb SATA HDD on a motherboard with the Promise PDC20378 RAID Controller chip. There is some reference to RAID 10 on an older version of Ubuntu but I am unsure how to modify this to my requirements. Am assuming that although Linux RAID is called Fakeraid, you still connect your array of drives to the onboard RAID connection [in my case SATA_RAID1 and SATA_RAID2] as you do for Windows? I also assume that the RAID array has to be set up early in the installation of Debian minimal install as per your tutorial. Can you assist with a short Tutorial please?
