[linux-lvm] mirror setup with LVM

[fabio_s at inwind.it]

Hi all,

I have a redhat 9 linux already installed and I'd like to add a second disk to
be used as mirror.

I assume it's easy to do this during linux installation.

Does someone know how to do that without destrying data on the first disk?

Thank you!


Fabio
