Linux has been flawlessly running on a SW raid-1 for almost 5 years now (thanks a bunch to all the ones who contributed), but I always felt the lack of having such a solution under win 2K. Since there are some rather inexpensive (S-)ATA-Raid cards around I thought about buying one of those to finally mirror the Win-Partitions (I know the cards suck re preformance and all the rest of it). As far as I know, using kernel 2.6 (probably SuSE 9.2/9.3), there will be only dmraid supporting ataraid, but I actually could also live very well with a sw-raid solution (in fact I did for quite some time) and not be seeing the Windows partitions from Linux at all. So my question is the following: Has anybody experience with the following setup: - I would like to set up the two disks as a mirror raid set using the ATA-Raid card. - A reasonable portion of the raid-set will then be partionend and used by windows. - (Probably) I would actually use a DOS/Win based program to pre-partition the rest of the mirrored disks for Linux - the remaining Linux partitions will then be used as a SW-Raid-1 set (with a LVM on top of it?). As far as I know, Linux should be seeing all the partitions made for the "hardware" raid windows setup as being separate partitions on the two hard disks (identical layout). So I should be able to mirror them using sw-raid. Has anybody done that? Is there anything that looks like it will be impossible to do? Any hardware I should avoid? I am aware that I will probably do a lot of manual tweaking during the first Linux install, but I think I can handle that :-). Before buying all that stuff and put in the effort it would be reassuring if I knew it's feasible.... Thanks in advance, Stefan
