For LVM there's more steps but basically it depends on 'pvmove'. And for Btrfs it's 'btrfs replace' - both are live migrations and so long as /boot is separate, nothing else needs to be changed or updated. > After running grub2-install and grub2-mkconfig, If the computer has BIOS firmware, then grub2-install to a whole block device is indicated. If it's UEFI firmware, then grub2-install shouldn't be used. Instead use: sudo dnf reinstall grub-* shim-* Also note starting with Fedora 34 that UEFI and BIOS have /boot/grub2/grub.cfg now due to feature: https://fedoraproject.org/wiki/Changes/UnifyGrubConfig > my machine will not boot. > I performed the changes using a F33 live DVD which also fails to boot. > After plugging in a USB-connected SD card with Centos 7 on it, > the F33 live DVD decided to boot. > It is what I am running now. > The complaint is UUID 2b82edc2-4eb2-44a0-8b5b-c71da0de9b3a not found. > While running F33 live DVD I get > blkid | grep 2b82edc2-4eb2-44a0-8b5b-c71da0de9b3a > /dev/loop1: LABEL="Anaconda" UUID="2b82edc2-4eb2-44a0-8b5b-c71da0de9b3a" Sounds like /etc/fstab has the wrong UUID. > I backed up sda5 with rsync -auHAXUUx . > I copied from the backup with the same flags. > I edited the new etc/fstab to point at sda3, > actually LABEL=local3slash . OK but did you label the file system 'local3slash' at mkfs time? > > As root: > grupb2-install This is missing a block device. > grub2-mkconfig -o .../local3slash/boot/grub2/grub/cfg That's probably only going to work in a chroot where everything is properly assembled in advance. The easiest way to get it properly assembled for you is the rescue option in the troubleshooting menu on netinstall media. And since /boot is a dir in the copied sysroot... yeah dracut. A neat hint is to search a live install's program.log for 'rsync' to see what command is used for a live install. 08:18:29,672 INF program: Running... rsync -pogAXtlHrDx --exclude /dev/ --exclude /proc/ --exclude /tmp/* --exclude /sys/ --exclude /run/ --exclude /boot/*rescue* --exclude /boot/loader/ --exclude /boot/efi/loader/ --exclude /etc/machine-id /run/install/source/ /mnt/sysroot A lot of that does translate into -a option. -- Chris Murphy _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
