Yes...I have a ProLiant 1600 with the 2DH raid controller with 3 9gigs running raid 5. All system partitions are contained in this raid group. In order to accomplish this I had to put a small scsi disk on the onboard controller, install onto this smaller disk, recompile the kernel to include the ida drivers. Once the machine recognized the raid array I then partitioned as I wanted and moved the filesystems (find . -print | cpio -pdvm /mnt/newfilesys). It took a little finessing with boot device orders and the system partition but the machine hasn't had any problems... If I was doing it again I'd probably throw another disk in and mirror as the performance is probably hurt a little with raid 5. One thing to remember is that it probably is a good idea to keep your swap off the mirror as it would kill your performance...I just kept the scsi disk on the onboard controller for swap. You could just as easily use the raid utility and set aside a swap disk that isn't mirrored. Oh...and the machine is running 3.2 --Ian _____________________________________________________________ Ian Clendaniel Conectiv Systems Architect Infrastructure Management ian.clendaniel@conectiv.com http://www.conectiv.com Int:235.5577/Ext:302.451.5577 Pager:800.225.0256 PIN:207595 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
