True. I do agree. Right now I don't have the "economy" to buy additional hardware so I have to do the best thing with these drives (with the possibility to add new ones or replace old ones for bigger drives.). //Anders _______________________________________________ linux-lvm mailing list linux-lvm@sistina.com http://lists.sistina.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://www.sistina.com/lvm/Pages/howto.html
