You should not trust anymore the old method for naming devices ("/dev/ sda...") as it can change at a random basis, but use persistent naming¹ (by-label, by-uuid², by-id, by-path) for your disks, even more with USB/ hot pluggable devices. BTW, shouldn't lvm2 care about this automatically? :-? ¹ http://wiki.debian.org/Part-UUID ² AFAIK, this is the preferred/recommended method in Debian Greetings, -- Camaleón -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
