hi giulio
what would be the point of making swap a raid0 or raid1 device ??
- if you have problem... the machine will most likely
shutdown and you lose all swap data....
just use a regular swap partition as swap... not /dev/mdxx
i'd try to use...
/ /dev/md0 - so tht you can usually get into standalone mode
/tmp /dev/md1
/var /dev/md2
/usr /dev/md3
/home /dev/md4
...
