[gentoo-user] Help with nvidia fake raid.

[Allan Spagnol Comar]

Hi list,

I have been trying for 5 days now to install a gentoo system on a
nvidia mother board with fake raid, I already have a windows system on
the machine that needs the raid and I want to install gentoo on it.

I have followed instructions on
http://gentoo-wiki.com/HOWTO_Install_Gentoo_with_NVRAID_using_dmraid
I was succeeded on installing gentoo base system and grub :-), but,
when I boot the systems ask for real_root /dev/mapper/nv_xxxx device

I had try the hard way, open a shell when it ask for real_root and on
/dev/mapper is just control.

I had try with genkernel and on the same situation on /dev/mapper/ has
control and my disk, but none of the partitions.

I am so close of making this work, but is really frustrating get stuck
in something like that for so long.

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 ...).

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 ).

Why not? Can you explain with some details?

I thought I had make clear before, lousy english .....
I had a separated boot partition but in the raid set, this was what I
really mean on previous e-mail.
sorry,

anyway, I don´t know why it doesn´t work. once that the boot starts..... :(

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.

I found the link which could be relevant and give further information to 
Google around:
    https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=186842

The chief problem (at least in my case) was (taken from above link) is 
that 2.6.16 introduces "the problem to this patch that limits dm-stripe 
to targets that are multiples of the chunk size". Depending on your RAID 
configuration, NVRAID could make use of dm-stripe, and thus you'll run 
into issues.

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

[Robert Walter]

hi 
what kernel version do you use? 2.6.16?
i run gentoo amd64 on nvraid (nforce4) and can't switch to 2.6.16 because the 
real_root isn't found. could be the same problem with you. i stick with 2.6.15 till the problem solves itself ;) 
maybe 2.6.17 works. though, haven't tried yet.
best regards robert

Hi, I had tried with kernel 2.6.15 ...... it appears to have pass the
point before but it freeses ker initialization saying that it can´t
find /linuxrc and /bin/bash.

any clues ?

if I use genkernel I had a kernel panic !!!!

thanks for attention. Allan
