Rename A Volume Group On Ubuntu 16.04

When using LVM, the vgrename command can rename a volume group. But there are more steps required in order to get the OS to use the new volume group correctly.

  1. sudo vgrename <oldName> <newName>
  2. sudo vgchange -ay
  3. Modify files that contain references to logical volumes from the old volume group:
    • /etc/fstab
    • /boot/grub/grub.cfg
    • /etc/initramfs-tools/conf.d/resume
  4. sudo update-initramfs -u -k all
  5. sudo shutdown -r now
