Thanks for attention, Allan Hi Allan, I believe I had pretty much the same problem as you, finding that the initial install went fine, but trying to boot with the new kernel (after using genkernel with the dmraid option) failed. I found the issue lay with Linux kernel 2.6.16 - I read a post somewhere (which I have since lost track of) that hinted a bug/feature of 2.6.16 meant some partitioning schemes would fail to be detected correctly under NVRaid. The solution for me (so far) has been to run 2.6.15, at least until 2.6.17 goes Gentoo-stable. In other words, I have masked 2.6.16. Hope that helps, Dave. smime.p7s Description: S/MIME Cryptographic Signature

Depending on your RAID configuration, NVRAID could make use of dm-stripe, and thus you'll run into issues. smime.p7s Description: S/MIME Cryptographic Signature

Hi David, I will try downgrade the kernel, I will let you know if works.

Thanks for attention, Allan Hi, No experience with RAID but do you have a separate /boot partition. Assume you're also using an initrd (with genkernel ... --dmraid ...).

Re: [gentoo-user] Help with nvidia fake raid.
no, I do not have a separated boot partition because I just have 2 disks with the raid, so I cannot have the separated boot partition. But the boot starts and initrd and linuxrc are loaded ( apparently ).
