I there everyone!

I installed gentoo using Lxnay RR64 LiveCD, on a DualCore Amd64, with two Sata disk with DFI Lanparty motherboard RAID-0.

Here, in the liveCd, i can do this:

It's probably more to do with those "Buffer I/O Errors" than dmraid per se. (Sorry, not much help!)

OMG....

I'm now with the LiveCD. I open 2 shells, one chrooted to my new-crashy environment.
Both answer like this:

You can set the version of dmraid that genkernel uses in the /etc/genkernel.conf file, but you will have to put the tarball into /usr/share/genkernel/pkg/ manually if it is different to the version in the genkernel ebuild.

The other thing you could try to resolve your problem (which is possibly due to having two different ataraid signatures on your disks) is to use the dodmraid="xxx" option on your kernel boot command line in grub/lilo. Maybe dodmraid="-f nvidia -ay" but you will need to experiment! You could also try and wipe the bogus "sil" signatures if you can work out where they are on the disks.

SOLVED!

Editing genkernel.conf and setting version to prior (1.0.0-rc8) fixed it.

Thanks ebichu, =)

/me is happy now.

I have the same problem. My running kernel is 2.6.15-r1 patched with reiser4.
I tried two no-sources kernels. 2.6.16-? and 2.6.17-?.
Both of them produced the same as above during boot. Dmraid partitions were not recognised, so I couldn't boot.

I'm afraid to recompile dmraid with symlink for kernel sources linked to no-sources kernel, because then I might not be able to boot back with my current 2.6.15-r1 kernel.

Any Idea, how to solve this. I don't use genkernel.

I've set symlink for /usr/src/linuxI to no-sources kernel recompiled device-mapper and dmraid. And then recompiled kernel. No change. Still boot error.

As I wrote. I don't use genkernel.

Yes, I use initrd

ebichu · Posted: Wed Apr 12, 2006 4:36 pm Post subject:

Well you probably know more than me then. Genkernel seemed the easiest way to go when I started using 2.6 kernels on an ATARAID system. I've never tried mkinitrd or constructing initrds manually. Genkernel's not so bad though.

Here is the howto with genkernel and without genkernel
http://gentoo-wiki.com/HOWTO_Install_Gentoo_with_NVRAID_using_dmraid

Genkernel is easy, but without you can have only what you want in your kernel. Genkernel is no solution for me, that's why I dont use it.

If i recompile dmraid and create new initrd with no-sources symlinked to my /usr/src/linux folder, then I don't know if I'll still be able to boot with my older kernels.

I tried your way, ebichu.
Compiling errors ocurred with my old configuration, so I said, let's try this genkernel once again after a long, long time. I compiled full tree for no-sources-2.6.16-no1 and no-sources-rc1-2.6.17-no2 both produced the same error.

Problem was with udev and genkernel. I changed udev version in gekernel's ebuild, emerged it again and it compiled kernel ok.

But...

It now doesn't find my nvidia-raid partitions. Boots ok, but dmraid doesn't find disks. Before dmraid starts I see in the output that devfs doesn't find /dev...

What now?

I thought that devfs is obsolete

I'll try with no automounter support in pseudo filesystems (kernel config)

I can still boot my other kernels and they work ok.

I found out that it is dmraid problem. Version 1.0.0-rc11 will solve this problem with 2.6.16 kernels.
