Dear all,
in fact, I got the same configuration on my old server. RAID1 for / and
a RAID5 for /home.
I installed that some years ago, following these instructions:

You even can, apparently, install grub on the 2 discs so you have some
kind of failover when one disc dies (which it actually did some time
ago). So the downtime of the system is minimal next to nothing,
depending on whether you can hot-swap your discs or not (I cannot as
they are IDE).
My 2 pence :-)
All the best
Jörg

Sure it is. The only issue you may run into is that the partition

to deal with RAID partitions. My solution has been to put /boot on
Compact Flash that is plugged into the motherboard IDE connector via a
$5 adapter card.
Hhhm,
I have a bunch of servers here with / as a RAID1 software raid volume
and grub works perfectly (does seem to have problems with booting off of
a RAID5 volume though). Furthermore, with a little manual intervention,
you can install GRUB to the MBR of boot drives and everything works fine
in the event of either disk failing (or at least being unplugged from
the motherboard which was all I did in testing).
