[linux-lvm] lvm'ing root fs



I've created an init ramdisk (lvmcreate_initrd), and now I'm in the process
of trying to copy my root fs to my new lvm_root.  To reduce the disk I/O,
I've gone down to single user mode to try to copy (cp -a *) all my files
from root to lvm_root.  Twice I get the same results:

# cd /
# cp -a * /mnt/root_vg
cp: /mnt/root_vg/proc/kcore_elf: Invalid argument
cp: proc/sys/net/ipv4/route/flush: Invalid argument

This is all I see on my screen, then at some point, the copying stops, and
my system will not respond to keyboard input, except it will respond to
Alt-F1/4 to switch virtual terms, but still no keyboard input accepted.

Should I tar/untar instead, or did I miss some fundamental step?

Thanks,
Marco
