You have RAID1 but I have RAID5 which I'm installing Linux on it.

Also the only raid I used with Linux before was mdadm - it supported mirror
too. Actually if I just wanted use raid1 I wouldn't buy nothing since Linux
can set it up anyway. You had that system since 10.3 but this's the first
time I put Linux in this system.

So you have 3 disks?


Yep, but only 2 in my RAID1

Having never tried RAID5 before, I didn't know a recompile would be
necessary.
But, I do agree with your basic premise that dmraid works great and openSuSE
should fully get behind it and support it. They have been making improvements
on properly handling dmraid arrays on install and making grub behave properly
with them.
