Raid is up but won't mount

["Chris Mason" <lists@masonc.com>]

I decided to move my image server to a rack mount case today. It is
configured with four 160 GB IDE drives as a raid 5 array. Only the enclosure
was changing, everything moved across, so it should have worked without
incident.

I shut the server down after first checking the raid system was synced. 
I moved the 4 RAID components to a new case after the motherboard and the
PSU were installed and the boot drive was working. The system booted fine,
the array reassembled, but then I got an error as the array was mounted. I
can't figure out what went wrong and what to do about it. Any assistance
appreciated, I don’t know what to do next.

OS: Centos 3.3
CPU: Celeron 1700MHz
RAID5: 2 x Promise ATA100 interfaces, 4 x 160GB WD1600 drives as
hde1,hdg1,hdi1,hdk1

It seesm to be a ext2 problem:

EXT3 FS 2.4-0.9.19, 19 August 2002 on ide0(3,2), internal journal
