Exactly. Anaconda (the Fedora installer) sometimes wipes devices during install, I would not be surprised that this can happen even during upgrade. (In install, it usually appends device to LVM, so be sure that this device is really not in use or luksFormat break your system even more.) Usually you should do: 1) blkid -p <device> - check what is not on that disk (partition table added, lvm, mdraid, fs... ?) 2) check if the device is not use - lsblk, pvs, lvs -o+devices ... I am afraid that if device was wiped, no way to get you data back (without LUKS header backup). So, once you are sure, just reformat the drive. Maybe you will have to setup UUID (check fstab/crypttab) - you can set UUID on the device itself (see man cryptsetup luksUUID) or just fix files mentioned above (if they contain UUID reference). > As to grub.conf, Grub legacy uses menu.lst, and grub 2 > uses grub.cfg, so I am not really sure what you are talking > about. Upgrade F15...F17 seems to switch grub->grub2 (I had to fix 3 borked systems after upgrade already so will not better comment it anymore:-) Whatever, grub2-mkconfig is very useful tool... also see http://fedoraproject.org/wiki/Common_F17_bugs and other pages, just search Google Milan _______________________________________________ dm-crypt mailing list dm-crypt@xxxxxxxx http://www.saout.de/mailman/listinfo/dm-crypt
