Dear All, I have a problem with dmraid and Intel Software RAID1 on Redhat Fedora Core 6. I setup RAID1 in BIOS with 2 hard disk and then I installed Redhat Fedora Core 6. During installation Fedora recognized only one drive (device-mapper) and was installed successfully. When one of my hard drives failed, I replaced it with another one and I imported it into RAID array, the RAID status in BIOS became "Rebuild" but during boot time I received kernel panic message and my system could not load the operating system. For more information I should say that my RAID Controller is "ICH8DO" and my motherboard is "AIMB-764". Best Regards.
