Hi Sir, Saw this video and have a query, dont we need to create a new pv on the new disk partition we have created? Can we directly use the new partition to extend the VG?

Hi sir how to move /boot to new disk ?

[@NehraClasses]

Yes it is possible. Also its not easy. If you intent to move separated /boot partition and or / partition you should consider first of all changing the fstab entries. If you are moving the files to new partition then don't forget to use cp -p while copying to preserve permissions. adjust then your /etc/fstab to the new UUID's of partitions that you will use. You can get the partition uuid by running blkid /dev/sdXn where X is name of the drive and n number of partition. You can also use blkid to attach labels to your partitions and then mount via labels which is much easier read man blkid to learn more. After you change the partitions and adjust /etc/fstab you should run the update-grub - available on Debian/Ubuntu script or grub-mkconfig -o /boot/grub/grub.cfg to generate a new config file and then reinstall grub into the first hdd that you bot from. grub-install --recheck /dev/sda Of course do not forget that when copiying mount a new / or /boot partition on /mnt and after copying all of the files mount them as / and /boot chroot and only then run update of the grub if you want things to be done correctly.
