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?
