from what you're saying...there is NO point to using the hpt-370
controller... any motherboard will work for you ....
you're running software raid0/1 as defined in the kernel
to run at ata100 speeds you need to patch the ide driver
in the kernel...
download the patch and follow the instructions in it or
search google for those keywords i posted earlier...
basically to patch things... ( not sure if correct for the ide patch )
cd /usr/src
patch -p0 < ide_patch.txt
- if it failed ot patch...you'd get errors
cd linux
make dep ; make clean ; make bzlilo ...etc..
also... never buy hardware unless oyu know linux has a driver
for it and that you saw it working...
right now you can just use any ide port on any motherboard
and you should not see any difference other than /dev/hda
and /dev/hdc is used instead of hde/hdg

How would I used the ata-100 patches however, if I am installing the
system on my ATA-100 drives? I got the feeling that older versions of rh
at least w/o 2.4 kernel did not support the hpt-370 w/ata-100 *at all*?
The 2 drives are plugged physically into the hpt-370 controller (1 per
cable of course), but I am actually running the raid via software
(here's my raidtab:)
raiddev /dev/md0
raid-level 0
nr-raid-disks 2
chunk-size 64k
persistent-superblock 1
#nr-spare-disks 0
device /dev/hdg1
raid-disk 0
device /dev/hde5
raid-disk 1
The reason for running the RAID via software is simply cause the folks
at Highpoint haven't released a linux module/driver/etc. for the hpt-370
that supports the raid functions (ARGH!)

Alvin Oga wro! te:hi marcus
you need to download the ata-100 patches
search google.com for
"raid ata100 patches"
read the posts and info and experiences of others on
rh and debian et.al w/ ata100 and abit mb's
---
am confused...
are you using the abit onboard raid controller HPT370
( no /etc/raidtab needed ) or are you using sw raid ( /etc/raidtab ) ???
striped raid0 is good for reading data back twice as
fast.... does not help much in writing data...
- good for webservers presenting pages...
have fun raiding

I've been following this list for a few weeks now, starting to become
more and more interested in Debian. Right now I am running my box on
redhat 7.1 (2.4 kernel), on an IDE Raid 0 (striped) array. I am using
the HPT 370 Raid controller on my abit kt7-raid, in software mode
however, as the chipset is only supported as an ATA-100 controller in
linux, not a raid controller :(. How I did this was during the
installation of RedHat, it allowed me to create a raid partition for /.
I also made normal ext2 partitions for /boot, and a swap partition. Now
my system boots fine off of /dev/md0.
Now, to come to the point(!) I'd like to know the status of a deb
distrib (Woody i guess?) that ships with 2.4 kernel packages (for
ATA-100), and will allow raid partitions set up in installation. I have
heard that if you install using apt-get to grab just the packages you
! want, could it be somehow setup to install 2.4 kernel packages instead
of the default? is the default in woody or sid already 2.4? (I don't get
the impression it is, but..) Is their any way to set up a raid partition
in the setup process currently? if not is their one being planned and/or
tested?
Basically, what do I need to do here to get myself converted ;-)
Thanks,
Marcus
