Lvm2 Booting - Can't Find Ext3

[yorgodillo]

Dear All,

I have Fedora Core 4.

I created a volume group called lvm-root.

In that volume group I created only one logical partition, called lvm0.

I mounted it and copied my current root filesystem there (using cp -ax).

I used mkinitrd 5.0.8 with the appropriate fstab file (see bottom) and the kernel
version 2.6.11-1.1369_FC4.

I copied the /boot to a new non-lvm partition from where I am booting in order to activate the new root filesystem, but this seemed impossible as I get
the following error :

VFS: can't frin ext3 filesystem on dev ram0

Note : before that message I got the message that lvm-root was
successfully activated.

My fstab file is :
===============
# This file is edited by fstab-sync - see 'man fstab-sync' for details
/dev/lvm-root/lvm0 / ext3 defaults,errors=remount-ro 1 1
none /dev/pts devpts gid=5,mode=620 0 0
none /dev/shm tmpfs defaults 0 0

/dev/fd0 /media/floppy auto pamconsole,exec,noauto,managed 0 0
/dev/hda /media/cdrecorder auto pamconsole,exec,noauto,managed 0 0

My initrd's init script is :

Also, my partition table (I am booting from sda9 and trying to mount the root filesystem located at sda10):

Disk /dev/sda: 37.0 GB, 37019566080 bytes
255 heads, 63 sectors/track, 4500 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

/dev/sda10 3043 3518 3823438+ 8e Linux LVM

Finally, the grub.conf entry for doing all this:

root (hd0,
kernel /vmlinuz-2.6.11-1.1369_FC4 root=/dev/ram0 rhgb quiet
initrd /initrd-lvm2-2.6.11-1.1369_FC4.img

Thanks in advance smile.gif

You should specify the path to your root in the kernel line in grub.conf:

kernel /vmlinuz-2.6.11-1.1369_FC4 root=/dev/lvm-root/lvm0 rhgb quiet
