I will explain my problem a little bit before asking the question again. At the moment I have a 136GB HD installed on which Debian runs (ext3). I want to make a raid 0 with 2 other drives (500GB each) and these drives need to be able to be formatted as NTFS, as I want them to be the place where samba server put all the files. Later on, I want to add 2 more drives (500GB each) to make a raid 0+1. Is this possible?? I'm sorry if this question was already done, but I have search for it but couldn't find it.
