RE: Hardware IDE ATA Raid 1 support in Linux Debian - Linux disapointment
Thanks for you msg.
What i'd like to would be to use hardware raid, i'm used to Compaq (HPAQ)
servers whith smart array controller i thought i would get the same kind of
functionality (limited to raid 0 and 1) on this ide controller.
I guess i'll toss out this controller and use the onboard ide controller (1
disk on each channel as i have a SCSI CD-Rom).
Maybe i keep the controller just to try with a newer kernel.
Guess Debian is out of hardware manufacturers linux distro list.
I understand the difficulty to make a "for Linux" driver, and hope that LSB
get's more attention in order to easy this Linux difficulties which M$
doesn't have.

You could always use the controller as simple IDE controller using standard
kernel drivers and build software RAID. For RAID 0 and 1 this usually
produces a very minimal performance hit. You have to jump through some loops
in order to make it bootable though. For information about that, here's a
page that helped me set up a simple RAID1:
http://unthought.net/Software-RAID.HOWTO/Software-RAID.HOWTO.html
There are native Highpoint RAID drivers in kernel 2.4.20 (IDE, ATA and ATAPI
Block devices -> Support for IDE Raid controllers), but I don't know how well
those work.

Building drivers for specific distributions is usually easier that producing
closed source "Linux drivers". When you write driver for, let's say RedHat
8.1, you know what kernel is installed and where to put config stuff. That's
a lot more difficult with Linux in general since it's an uncontrolled
battlefield. The LSB was supposed to make this easier, but... well... no.
If you want a well-designed system, use *BSD.
