I can't help you fix it, but I think your problem is that you have a clash of Volume Group names. Both your old and new disks are part of a VG called VolGroup00 and I have some ideas how to go about fixing that. I think if you can work out what the UUID of the Volume Group on your F10 disk is, you can run: vgrename <F10UUID> VolGroup00_tmp You should be able to see the UUID of that Volume Group from F10 with "vgdisplay" -- Sam -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
