[linux-lvm] lvm 1.03 on redhat 7.3

[James B. Byrne]

I am trying to mount a root fs using lvm on redhat 7.3 using the 
howto guide provided by sistina.com.  I am getting this message:

ram disk compressed image found at block 0
freeing initrd memory 1211k freed
VFS:mounted root (ext2 filesystem)
attempt to access beyond end of device
01:00:rw=0, want=4558, limit=4096
VFS: cannot open root device "vg00/lv01" or 00:00


Help!

Your initrd image does not work, it's to big.

Try uncompressing /boot/<your-initrd>.img (best you copy it to
/tmp/initrd.gz, gunzip this) and figure out the size. Round this size to
the next "regular" number and add "ramdisk=8192" or what ever your size
it to the append line in lilo.conf. rerun lilo and try again.

It might be required to boot from some kind of recovery device if you've
realy screwed up. hopefully you have something like this, otherwise
there are some generic solutions available on freshmeat.net

Cu,
    Goetz.

isn't this covered in the redhat manual?
well redhat provided lvm and mkinitrd tool do support it

i suppose you are running from a root on a partitioned disc
and you copied everything to your lvm root which is at
the moment mounted under /mnt/lvm
and that you have fixed the /etc/fstab under the new lvm root
to reflect the new setup: ie you have sth like
/dev/vg00/lvol3 / ext3 defaults 0 1

now run:
mkinitrd -v --fstab=/mnt/lvm/etc/fstab /boot/initrd_lvm `uname -r`
and use the newly created initrd to boot your system.
