i accept the fact that there's got to be some manual intervention in
that situation (whether at the console or via a remote console) and
either replace the dead drive or edit the boot command line to boot off
the second drive while i'm waiting for the replacement to arrive.

i use raid1 on all my systems (except those with HW raid-5 cards). even
my workstation. IMO it's worth paying effectively twice as much for disk
storage to avoid the risk of losing everything if one drive dies. that
plus a decent tape backup system saves a lot of grief.


PS: i made the mistake of using raid-0 on my home workstation a few years
ago. then my tape drive died, and i didn't get around to replacing it.
then one of the raid-0 drives died and i lost nearly everything - was
only able to recover about a third of what was on the disks.  never again.
IMO, anything that is so unimportant that you can risk it on raid-0 is so
unimportant that it doesn't need storing at all.

the only time i'd use raid-0 now is in an array of multiple raid-1
arrays joined into a single raid-0 array (i.e. raid 0+1). even then,
i'd probably prefer to use raid-5 if disk speed wasn't the prime
