RAID in Linux (was Re: SCSI and EIDE)

[Ricardo Kleemann <ricardo@americasnet.com>]

Hi guys,

starting a new thread about the subject... ;-)

I'm still trying to get a grip on this...

Few questions:
1. can raid0/raid1 be done on either scsi or ide or both?
2. what's the difference between raid0 and raid1?
3. what exactly does it do? Does it mirror data accross multiple devices, 
and if so, how does it maintain the data in all devices?
4. How does one go about "creating" an md device? Would it automatically 
mirror a "non-md" drive into the multiple devices?

Thanks!
Ricardo
