...I did. In fact, in order to get the 5th drive to run my tests, I
had to cannibalize an older RedHat system that is 'wounded' because I
lost a cpu fan and damaged the cpu chip. I was going to replace the MB
in that system at some point but now, I may also be short a drive having
had to use it in what I thought was ample hardware; A new ASUS system
MB with 4 SATA drives and with a so-called hardware raid controller
built-in to the MB. As it turns out, that controller is a 'fake-raid'
which borrows cpu cycles but still, with the hardware I had, under
Windoze, the configuration would have worked (demonstrated), but I
refuse to contaminate my system with that OS and I believe anything
Windoze can do, Linux can (or should) be able to do better.


Thus, use software raid in linux, which also works out of the box. No need to use the fake-raid drivers, and has probably the same speed, and decidly
better support and compatibility.

I don't see any advantage in using the fake raid method, except using windows - and you aren't, so why go the difficult road?

With software raid you do not need an extra drive, just a plain /boot partition replicated on all disks. I'm almost sure it is documented somewhere.


I'm planning on experimenting with that. I recently bought an IBM Netfinity X232 server, with 4 18G SCSI disks. I've currently got SUSE 10.2 running on it, but without RAID.
