Simply type "mount" and it will show you the mounted partitions. In
your case the problem probably is that you have mounted /dev/hda1 as /.

I doubt that the raidtools allow to mirror a mounted system, and I
also doubt that you can create a raid without destroying existing data.

I do not Windows NT. It is simply that way: If someone needs that
feature and s/he is capable of programming, s/he may implement it. It
seems, like no one was yet able or willing to do it.

Yes, you will.

Support for raids is apparently still missing in YaST.

Having the root file system to boot from the raid is more
complicated. This will not work with the default SuSE kernel,
unfortunately. Either this will be fixed in a next release or you have to
built your own kernel to do that.
