Hi Heinz, I am bit new to efforts of RAID5 support in dmraid... Let me describe what I have here: I have that ASUS M8R32-MVP motherboard and it has two SATA controllers and so two SHRAID bioses. Although I am playing with ULi ones, since it supports up to 4 drives (other one - SiL - has support for two and one of them is external - I did not tryed it yet). So, my config now is 3 300G disks configured as RAID5 in bios. So, computer can boot from this shRAID5 and I managed to install Windows there as well (although I needed to go buy floppy drive to do that, since windows of course requires drivers on installation phase). So, as long as I am not using those 3 hard drives for anything useful (I am using linux on that computer from USB hard drive) - I can do any silly things there. So far - kernel does recognizes all three HDD's as sda, sdb and sdc, although can see partition only on one of them (that is understandable, since RAID5 is employed there). Running dmraid -rD (or with any other swithces gives same result - No Software RAID disks. What else I did - pathced kernel with RAID-45 (do not remember exact name), although hunk#9 did not succeed (I am using 2.6.17-rc1-mm2 kernel) and I have no clue what to do with it. So, as usual - if you can provide me with instructions on what to play there - I willingly will follow with no problem.
