I have an FC2 system with six SATA drives, configured as three software RAID-1 pairs. Unfortunately, the /boot partition (and MBR, etc.) is non-RAID, so the system cannot boot if the drive containing /boot has failed. How can I configure redundant boot?
One pair of drives is connected to an Intel ICH5 controller on the motherboard. This can be configured as 'hardware' RAID in the BIOS, but there is no corresponding driver in FC2. There is a proprietary (binary) driver available, but I found several postings advising against using it.
A second pair of drives is connected to an on-board Promise 378 controller. The BIOS does not seem to allow booting from it.
The third pair is connected to a PCI card with a Silicon Image 3112 controller. Same situation as with the ICH5.
As a result, I was forced to use software RAID for all drives.
1. Could you please recommend a reliable and reasonably priced SATA controller with hardware RAID-1 capability, BIOS boot code and a compatible Linux driver? or,
3ware cards (http://www.3ware.com) are pretty good. Not sure how you define "reasonably priced" though so they may be too expensive for your liking.
2. Has anyone had a good experience using any of the above controllers with proprietary drivers in RAID-1 mode, and achieved redundant boot? or,
3. Is there a way to set up two separate boot partitions, MBRs, etc., so that either can boot the system?
TIA,
Stewart
