Move Debian on to software RAID setup  Q I have been happily
running Debian Etch for a few months now, and would like to move
it from hdb to a software RAID 1 setup on hde and hdg, My
current setup is:  /boot on hdb1 using ext2. / on hdb2 using
ReiserFS. /home on hdb3, also using ReiserFS.  I can move things
to put /boot on md0, / on md1 and /home on md2 but how do I set
up Grub? I know that Grub reads hard disks and partitions from
zero, but what about RAID setups? How do I reconfigure and
reinstall Grub for my new RAID setup?  A You'd be surprised at
how easy this is to do with RAID 1. The individual disks can be
accessed as though they were standalone disks because the RAID
data is not written to the rootblock of the disk. If /dev/ md0
is constructed from /dev/hde1 and /dev/hdg1, either of those can
be used as the boot disk. They are probably labelled (hd1,0) and
(hd2,0) because /dev/hdb will be (hd0), but you can find this
out with Grub's find command.  touch /boot myraidbootdisks
#switches to grub prompt
