There is not enough space ("vgscan -- ERROR 28" check the file "/usr/include/asm/errno.h") in the ramdisk to create the file "/etc/lvmtab.d/vg3.tmp"
What files did you copy to your ramdisk ?
Best regards.

Hello everybody,
I'm new at using LVM and I ran into trouble using it. I've got problems mounting an LVM volume as root on my system running Gentoo Linux 1.4. My configuration is as follows (skip to the bottom of the text for the actual error message):
Gigabyte mainboard with onboard Promise RAID. I've got 2 80GB discs attached (same model) and configured as RAID1. I installed via the Gentoo RC1 Stage 1 CDROM. During boot of the CD I had to abort and add the "IDE0=0x9400,0x9802 IDE2=0x9c00,0xa002" parameters to be able to load the pdcraid module.
My fstab looks as follows:
/dev/ataraid/disc0/part1 /boot ext3 noauto,noatime 1 1 /dev/vg3/rootlv / reiserfs noatime 0 0 /dev/ataraid/disc0/part2 none swap sw 0 0 /dev/cdroms/cdrom0 /mnt/cdrom iso9660 noauto,ro 0 0 proc /proc proc defaults 0 0 tmpfs /dev/shm tmpfs defaults 0 0
I also compiled my kernel using the gentoo-sources, and with the following options enabled:
- LVM support - Built-in RAM disk support with initrd - DEV fs support - mount DEV filesystem at boot
- ReiserFS support
I also ran lvmcreate_initrd with the -M option, because everything is compiled in the kernel. Also, when I run lvmceate_initrd without the -M options, it returns errors and the lvm image is not created.
My grub,conf (linked to menu.lst) looks as follows:
default 0 timeout 30 splashimage=(hd0,0)/boot/grub/splash.xpm.gz
title=Gentoo 1.4 GNU/Linux on Antigone root (hd0,0) kernel /boot/bzImage root=/dev/vg3/rootlv ide0=0x9400,0x9802 ide2=0x9c00,0xa002 initrd /boot/initrd-lvm.gz
When I boot the system grub starts correctly, but when grub wants to boot my system the following messages appear:
Code: RAMDISK: Compressed image found at block 0 Freeing initrd memory: 994k freed. VFS: Mounted root (ext2 filesystem). Mounted devfs on /dev vgscan -- found inactive volume group "vg3" vgscan -- ERROR 28 writing volumegroup backup file /etc/lvmtab.d/vg3.tmp in vg_cfgbackup.c [line273] vgscan -- ERROR: "lvm_tab_vg_remove(): unlink" removing volume group "vg3" from "/etc/lvmtab.d" vgscan -- "/etc/lvmtab" and "/etc/lvmtab.d" succesfully created vgscan -- WARNING: This program does not do a VGDA backup of your volume group
vgchange -- no volume groups found
VFS: Cannot open root device "vg3/rootlv" or 00:00 Please append a correct "root=" boot option Kernel panic: VFS: Unable to mount rootfs on 00:00
Now, the strange thing is, when I boot via the CD and do vgscan and
vgchange -ay by hand, I can mount /dev/vg3/rootlv normally!
Does anybody got any ideas? I've run out of them
Thanks for any help in advance. When you need any more info, just say so.
Regards, Patrick
