I know this may be more of a hardware question than a specific RAID question, but here goes. I just got a DPT RAID controller, but my motherboard has a built-in scsi controller. So I have two scsi controllers. My problem is that I have a resource conflict between the RAID card and the on-board

I've installed the latest raid versions with 2.1.131-ac11 in two machines, one a raid5 with root-raid, another with raid1. The raid5 machine was upgraded from version 98-09-13, the raid1 one from the pre-historic 0.36 (with 2.0.33). Everything worked fine from the beginning. As expected, I had to

Thilo's fix for mkpv.c appears in a different form in raid_io.c. I think the code would be more consistient and portable if the following lines were removed from raid_io.c. raid_io.c:21:#ifndef BLKGETSIZE raid_io.c:22:#define BLKGETSIZE _IO(0x12, 96) /* Return device size. */ raid_io.c:23:#endif
