Be sure to do that completely, by hooking the drive up to another machine
and doing (if the drive is the secondary master):
dd if=/dev/zero of=/dev/hdc

Now remove the slave, and check that the system boots OK from the master.
If my guesses are correct, it won't. That's where the LILO step will need
to come in, to make sure that the new drive is made bootable. The RAID
restoration will not cover the master boot record, only the file systems.
In order to test this thoroughly, you will need to do my modified setp 4 -
because otherwise your original master boot record will be still on the
drive - but it wouldn't be on a new replacement drive.
