software RAID with BIOS support -- such as for example my

make use of my "SATA fake RAID" ???
Yes, it can (sort of). But the procedure is long and complicated
and will probably change with SUSE Linux 10.1.
I'll write the procedure down in a few days when I'm not overloaded
with university work anymore.
Is there (or will there be) support for the fake-RAID
detector/drivers like sata_nv and/or installing Linux RAID based on
fake-RAID configuration? I have been googling my fingers off and
have been unable to find any at-all-user-friendly way to install a
current Linux distribution on a RAID 1+0 array of drives.
sata_nv is a hardware driver for the nvidia sata chipset, not for the
fakeRAID part of the chipset. dmraid is a software package to layer
an emulation for fakeRAID on top of existing hardware drivers.
I, personally, would be happy to use Linux software RAID BUT I have
found it extremely difficult and problematic to set up.
With YaST2, setting up native Linux software RAID is done in 3 or 4
clicks during installation.
I tried installing using SuSE 10.0 RC1.
It does NOT let me setup DRIVE arrays or 1+0 arrays of any kind (with
however many clicks).
I could set up either RAID 1 or RAID 0 partition arrays but it takes a
few more than 3 or 4 clicks (which is OK if it is doable).
With hardware RAID (3ware, LSI, ...) I set up DRIVES in a RAID 1+0 or
RAID 5 array and then treat it as one big drive when partitioning
and installing.
I believe, with newer kernels/mdadm/... that it is possible to create
drive arrays (instead of partition arrays) BUT this does not seem to
be supported by any current distributions installers.
Did you try YaST2?
I tried installing using SuSE 10.0 RC1
Is SuSE 10.0 RC1 installer using YaST2?
If it is not using YaST2, how can I install using YaST2?
Do I have to install SuSE on single drive,
then use YaST2 to build a RAID 1+0 drive array
then transfer the install to that drive
then fix grub to boot from that drive
etc.
It would be great to be able to establish an array of drives in the
fake-RAID BIOS and have the installer/grub/... detect that setup and
use it for the basis for the Linux software RAID OR use the correct
driver (eg sata_nv).
Linux software RAID and fakeRAID are totally incompatible.
OK. Scratch that hair-brained idea.
Alternatively, if the installer allowed establishing two drives in
RAID 0 (or 1+0) and then partitioning the resultant /dev/md1. I keep
reading that /dev/md1 is just another block device but the installers
do not seem to treat it as such.
Should work with YaST2.
SuSE 10.0 RC1 install does NOT allow partitioning the resultant
/dev/md... block device.
