I have been using Linux 2.2.x and RAID 1 happily. Because of netfilter, I must move to Linux 2.3.15 or higher. It seems that RAID 1 was disabled from 2.3.15 and above. The only options available are Raid 0 or Linear. Even in the kernels where RAID1 is an available option, 2.3.25 for example, it does not work. You boot the system and it says that RAID 1 is an invalid RAID type, only RAID 0 and Liner are allowable. Despite many searches, I have not found any reference to why RAID 1 was disabled from the kernel in these newer releases. I need help, any ideas?
