I just did a virgin install of RH 5.1 on a machine.  I upgraded the
kernel to 2.1.125 and installed raidtools-0.90 and tried to stripe
2 9gig barracudas as md0.  I edited the raidtab file (included below)
and ran raidstart -a.  It gives the following error:

# /sbin/raidstart -a      
/dev/md0: Invalid argument

Any ideas?


Other details:

K6-300 system
64mb parity fpm SIMMS
1mb L2 cache
Buslogic 950 fast/wide/ultra controller
1 x 4.3gig fast/wide/ultra IBM system disk
2 x 9.1gig barracudas
1 3COM 3C900 "vortex/boomerang" card
cirrus logic cheesy 1mb ISA video card
