Linux Software Raid 1 Recovery Question

[kentborg at borg.org (Kent Borg)]

So here I am a big fan of software raid and then I discover I am
missing a BIG aspect: how to survive a dead disk.  (A.k.a., I don't
understand how PCs boot.)

Here is the scenario.  A bootable software raid 1 Red Hat 7.3 install.
One disk is /dev/hda and one is /dev/hdc.  Each is a copy of the
other.  I am using lilo because the Red Hat installed knew how to do
that--or at least kinda.

Now imagine the disk on /dev/hda dies.  The disk on /dev/hdc should
keep running, or at least be bootable.  To simulate this I powered
down and pulled the IDE cable on the /dev/hda disk.  And it won't
boot.

What is the right way to do this?


Thanks,
