Hello, Last night I moved my primary hard drive from the standard ide controller to a onboard RAID controller, and added a secondary hard drive to the secondary raid ide channel. I set up the raid for mirroring and then rebooted when it was done copying the master drive to the secondary drive. Now upon the reboot I get a screenfull of errors and the drive cannot be mounted. Is there a special procedure I need to do in order for the drive to be mounted now that it's on a different controller and is now mirrored? I am using Debian 3.0. I can post later today the error messages but was curious if this was a known problem or if I did not do this correctly from the get go. I think I can put the main drive back to the other controller and boot from there with no problem, but we need the system mirrored for backup protection. Thanks
