Non-booting RAID1's my dilemma....
I'm running an FTP box for my school district using ProFTP. I have my configuration exactly the way i want it. There is no anonymous login and each user is chrooted into their home directory. I have a 15GB hard drive (/dev/hda) that is my boot drive, and houses a few local users home directories (basically its insurance to login if my RAID fails). All FTP users have home directories on the /mnt/ftp-raid folder, which is created from two IBM SCSI drives (9.1GB each) in a RAID1 meta-drive setup. However, when booting the linux box, i lose my RAID devices. I can recreate them using mdadm, but i would like them to be created at boot.
Before we beat the obvious to death:
- I have given RAID support to the kernel
- The device has been added to fstab
- When booting, i get an error regarding a bad superblock on the device. I have zeroed the superblocks on both drives several times.
- I am using ext2 as the filesystem on /dev/md1, but it gives me errors (at boot) saying there is no ext2 filesystem found.
- I have created my /etc/mdadm/mdadm.conf file using mdadm --detail --scan >> /etc/mdadm/mdadm.conf
- mdadm is running at boot-up as defined by /etc/rcS.d
- After booting and logging in, i can manually create the device using mdadm and naming the drives manually, but i cannot start the device up as a service and the existing configs.

RVHTC-Debian-FTP:/etc/mdadm# cat mdadm.conf

I can post more code if needed. I just figured that this would get the wheels turning. I've been looking and trying a few new things. Any help would be greatly appreciated.

can i possibly get this post bumped to the hardware forum...? I don't want to repost this under the hardware forum, and i feel that might be a better home for this question.
