Hi there I am a Newbie concerning RAID, but I got complete small Server for cheap, so I did not first check any Hardware-Compatiblity. I have a FastTrak100-PCI-Card with 4x 60GB IBM HDDs on a TYAN Thunderbold Dual Prozessor Mainboard with 2x PentiumIII and Adaptec SCSI-Contoller AIC-7896 onboard Now I want to set up a Debian-Woody-System mostly used as Gateway, Server,Proxy etc. and as file-server. I planned on using SoftwareRAID and setting up a small RAID1 Boot-Partition, and the others RAID5. I installed the system first on an extra HD and then moved the system onto the RAID-Partitions. It seems to work quite well, but I can not boot direkly of the RAID-Disks (I tried almost everything with LILO to get it to boot, but I think there are some Problems with the SCSI-onboard) So I have to use the MBR (hda) of the extra HD and it works, even changing form there to the MBR (hde) on the Raid-Disk and booting works. Does anyone know if it works to boot direkt of the off-board Raid-Partitions? and how do you have to set up LILO (or any other Boot-Loader)? Does it work with ataraid instaed of md? Has anyone collected experiences she could share with me? If it gonna work with SoftwareRaid, why should I use the stupid Hardware Raid with only level 0/1/10 supported ? Can anybody pointout to me advantages of the ATARAID? cu klaus
