mkraid /dev/md0 results in /dev/md0: Invalid argument - Linux

Attempting to construct a RAID-1 using a Promise FastTrack TX2 100
controller and 2 x 60gig IDE drives. I am using the 2.4.24 kernel
drivers for the fasttrack controller.

Using Raidtools version 0.90.0

I have added this entry to lilo to properly initialize the drives:

append="mem=1024M ide2=0xc000,0xc402,10 ide3=0xc800,0xcc02,10"

dmesg shows this for the drives and controller:

Kernel command line: BOOT_IMAGE=Slackware ro root=302 mem=1024M
ide2=0xc000,0xc402,10 ide3=0xc800,0xcc02,10
ide_setup: ide2=0xc0

....

hde: WDC WD600BB-00CAA1, ATA DISK drive
hdg: WDC WD600BB-00CAA0, ATA DISK drive

....

hde: attached ide-disk driver.
hde: host protected area = 1
hde: 117231408 sectors (60022 MB) w/2048KiB Cache, CHS=116301/16/63

Drive 0 is 57241 Mb (33 / 0)
Drive 1 is 57241 Mb (34 / 0)
Raid1 array consists of 2 drives.
Promise Fasttrak(tm) Softwareraid driver for linux version 0.03beta

....


My /etc/raidtab is as follows:

raiddev /dev/md0
raid-level 1
nr-raid-disks 2
nr-spare-disks 0
persistent-superblock 1
chunk-size 4
device /dev/hde
raid-disk 0
device /dev/hdg
raid-disk 1


However, when I attempt to create the RAID-1 device

I get this error:

/dev/md0: Invalid argument




The weird thing is this. Just out of curiosity I changed my raidtab
file to RAID-0 and tried to create the array. Everything worked
perfectly still using /dev/md0.


The onboard bios of the Promise card has the array created as RAID-1
which makes all this even more puzzeling.

Any and all help would be appreciated.
