Hi I hope someone has the answer to the next question. I'm looking for a way to use a server with three OSes, WITH ALL OSes USING (software) RAID-1. To be specific: Windows 2003 server, SuSe Professional and Fedora Core 3. The machine works with an Intel SE7520JR2 board and two SATA disk of equal size. The options I've come up with are as follows: A) 1) - Install Windows 2003 on the first 'simple' disk with a system/root partition and a data partition. - Upgrade this disk from 'simple' to 'dynamic'. - Mirror both partitions to the second disk. This will create a dynamic disk database which contains the 'simple' disk partition table info and ONE 0x42 partition table entry in the MBR at sector 0. Reverting to an 'simple' disk involves breaking the mirror and deleting the partitions on the second disk! 2) Create a boot, root and swap partition for SuSe on the first (now windows? 'dynamic') disk and mirror those on the second disk and install the software after this. 3) The same for Fedora Core 3. or B) 1) Install Windows 2003 on the first 'simple' disk with a system/root partition and a data partition. 2) Create a (mirrored) boot, root and swap partition on the first disk for SuSe, but do not install! 3) Create a (mirrored) boot, root and swap partition on the first disk for FC, but do not install! 4) Upgrade the (windows) 'simple' disk to 'dynamic'. or c) Make use of the RAID-1 option on the motherboard. If I do so, will I still be able to install SuSE and FC linux? Is any of these options valid? Will one work? I get the feeling none will, because of the 'thrashing' of the (normal) partition table info by windows. Is Windows the only OS that will be able to read the dynamic disk databse partition info? If so, is there an other option that will give me the result I desire? Many thanks in advance for any usefull reply! Fred. Send instant messages to your online friends http://uk.messenger.yahoo.com
