Accessing LVM on Software RAID1 from another machine

[Krsnendu dasa]

I have reverted back to my 7.04 installation (/ and /home on on Raid 1 disks).
I would like to access some of the files I had on the hardy system (/
and /home on lvm on a Raid 1 disk). How can I access it while running
7.04?
When I was running Hardy I used Webmin to mount the raid partition
from 7.04 to copy files.

It would recognize the Raid on it's own, but how would I access the
LVM on the Raid device.

If I have to I could try booting into Hardy, copying the files over,
then booting from Feisty again. But it would be good to know how to do
it the other way. I might have to do it again in future.

Thanks.
