[gentoo-user] booting with an lvm2 root. How do I make a working initrd?
Hi. I'm trying to get my gentoo isntallation to work, but I'm just ending up pulling my hair out. The setup I'm going for is a single disk, with two partitions One 100MB partition for /boot and the rest of the disk (~120GB) for LVM I've used the standard gentoo installation handbook + Gentoo LVM2 installation http://www.gentoo.org/doc/en/lvm2.xml + gentoo wiki HOWTO Install Gentoo on an LVM2 root partition http://gentoo-wiki.com/HOWTO_Install_Gentoo_on_an_LVM2_root_partition#Make_your_initrd and some random googeling From what I gather, I need an initrd image to boot with, so that it can load neccecary modules to be able to read the logical volumes. I don't want to use genkernel, but I still want it to work. The entry in the gentoo wiki is inkomplete (the links to the precompiled binaries are broken) when I try to run mkinitrd --preload md_mod --with=md_mod initrd-2.6.16-gentoo-r9 2.6.16-gentoo-r9 I allways get no temporary directory could be found (I'm runniing this from the live cd) In conclusion: how do I get/make a working initrd so I can boot with my lvm2 root? -- gentoo-user@gentoo.org mailing list

In conclusion: how do I get/make a working initrd so I can boot with my lvm2 root? that's much work to do it your self start building ext2 images or cpio's with static busybox lvm2 and write your own linuxrc (here you may cheat by looking into linuxrc from genkernel :-)). Don't forget to create dev-files and to include some modules. Sascha. -- gentoo-user@gentoo.org mailing list

Don't forget to create dev-files and to include some modules. Sascha. Yes. What Sascha said. I've had many a user (in #gentoo IRC) sneer at me for using Genkernel to produce a kernel + initramfs archive to boot up my RAID + LVM2 based system. But it's far simpler than reinventing the wheel by creating all that is needed to bootstrap the RAID/LVM2 setup (static bins, linuxrc script to start everything up, create device nodes, etc, etc). I don't see much value in doing it myself when Genkernel already does it for me. Also, you can do all the kernel customization you wish (within reason) even if you use Genkernel by using one of the --menu|x|g|config flags, and/or --oldconfig. -- +---+ | Jim Burwell - Sr. Systems/Network/Security Engineer, JSBC | +---+ | I never let my schooling get in the way of my education. - Mark Twain | | UNIX was never designed to keep people from doing stupid things, because | | that policy would also keep them from doing clever things. - Doug Gwyn | | Cool is only three letters away from Fool - Mike Muir, Suicyco | | ..Government in its best state is but a necessary evil; in its worst | | state an intolerable one.. - Thomas Paine, Common Sense (1776)| +---+ | Email: [EMAIL PROTECTED] ICQ UIN: 1695089 | +---+ -- gentoo-user@gentoo.org mailing list
