Greetings,
First, I should say that I am new to raid and never
setup raid before.
I attempted to make raid0 work on RH 7.3. This is what
I did:
(0) Configure raid0 on Fasttrack bios.
(1) Install RH7.3 as normal setup. (by the way, I
did attempt to setup software raid, but setup does not
like it, abort with error on two harddrives on raid
card)
(2) Installation was successful and once it is up
and running, I did:
modprobe ataraid
modprobe pdcraid
(at this point, I checked dmesg, I
saw ataraid/d0 was reported correctly:
ataraid/d0:
Drive 0 is 38166 Mb (33 / 0)
Drive 1 is 38166 Mb (34 / 0)
Raid0 array consists of 2 drives.
Promise Fasttrak(tm) Softwareraid
driver for linux version 0.03beta
)
(3) Then I tried to partition the raid array by
doing:
fdisk /dev/ataraid/d0
I simply created one primary partition, but
when I write the partition tables, it failed with this
message. Note the warning message.
(4) Reboot the machine, and install ataraid and
pdcraid as usual, but when I tried to fdisk the
/dev/ataraid/d0, it said
"No such device"!!!!!!!!!!!!????????????
===================================
Command (m for help): w
The partition table has been altered!
Calling ioctl() to re-read partition table.
WARNING: Re-reading the partition table failed with
error 22: Invalid argument. <-----------------------
???????????????????
The kernel still uses the old table.
The new table will be used at the next reboot.
Syncing disks.
=================================
By the way, if it helps,
My machine is Dell Precision 530, w/ 1 Xeon 1.7G +
512 MB.
Online devices are: one 17G scsi harddrive, one
onboard 80GB Maxtor and two 40GB Seagate connected as
two masters on Promise Fasttrack raid controller card.
The report from dmesg:

I came across the message board, and there seems to
have a lot of knowledgable folks here.
Appreciate any help or comments from you!
