The simplest approach is to add a kernel parameter which will assemble md5: md=5,/dev/md3,/dev/md4 root=/dev/md5 If that doesn't work, let me know and I will fix it. ByTheWay, you have your raid10 upside-down. It is more reliable to build raid1 arrays out of real drives, and then a raid0 out of the raid1s.
