Scan for and activate all lvm volumes: su -c "vgscan && vgchange -ay" Then have a look at what volumes you have. The first VolGroup should be your internal drive. You'll need to run something like: su -c "vgrename VolGroup1 usbdrive" You can tell grub to boot the USB drive by replacing its GRUB entry from root=blahblah with root=/dev/mapper/usbdrive-lv_root Of course, your initramfs also needs to support booting from USB.. -c -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
