I am running a Debian 3.1 (Sarge) server with Raid 1 mirroring on

Recently, one of the disks failed. The system sent root a proper e-
mail notification of the failure. Unfortunately,
the system seemed to continue to try to use the disk and operations
slowed to the point that the only thing I could
do was to power the system down and physically remove the bad drive.
I had thought to check the mdadm status
and remove the failed drive from the array by command.
My question is shouldn't the Raid system have removed the drive for
me after it had failed? Why was the system still
trying to do operations on it after noticing the failure? Was (is)
there something wrong with my raid configuration?
Are these IDE drives? Were they on the same cable? IDE is kind of
"fragile" -- a bad drive can cause problems with accessing the other
drive on the same cable. Ideally you want the two drives in a RAID 1
setup on separate cables -- this will give better performance, as well.
