you can do anything you like to the individual partitions
when you do mkraid /dev/mdo ... ( everything is lost that was previously
done so there is no point to doing anything outside of "raid commands"
- if you want to preserve /home ... tar it up before creating
the raid and do the raid stuff correctlt and than restore from
tar ...
when you keep your existing old /dev/hda1 intact and try to make
a raid1 mirror .... some of the "mirroring will not work" since oyu
didnt do a "mkraid /dev/md0"
- its a bad idea NOT to do "mkraid /dev/md0"
especially if you expect the mirror to work 100% correctly
like when /dev/hda is removed ( simulated failed disk )
lots of docs on up to upgrade /dev/hda to /dev/md0 ..
- but i dont recommend it or use it that way
ultimate tests ...
- pull /dev/hda
-- reboot ...
- than pull out /dev/hdc ...
-- reboot ...
if it passes your tests ... it works ..

that is done by "mkraid /dev/md0 ; mke2fs -j /dev/md0"
anything else is NOT raid and is wiped out anyway

thats the whole point of providing the url ..
- pick the one of dozen ways to upgrade from /dev/hda to sw raid
- and there will be conflicting "howto" instructions too
depending on what the resulting raid has to do and the process
of how to get there
