I install CentOS 4.4 without additional driver disk.
When I partition the disk, I create nothing on the raid 5, and I just create " / " " /boot " and "swap" on the raid 1.

And it works.

When I create a mount point /storage on the raid 5 and create " / " " /boot " and "swap" on the raid 1.

The error comes again, saying that there are inconsistency on the raid /dev/sdb1
