[linux-lvm] access files in an ext3 filesystem from lvm

[messmate <messmate free fr>]

Hi,
I've 2 distributions, one with LVM/ext3 configured and the second with
only an ext3 filesystem.
How can i acces the files in the LVM/ext3 from distribution 2 ??
LVM/etx3 is as follows:

                                       |-> lv1   
                                       |
pv1,pv2,pv3 -->vg1---|-> lv2
                                       |
                                       |-> lv3

Thanks for your help in advance
