Rename a Volume Group on Debian

Small post to explain how to rename a LVM volume group on Debian.

• Reboot your machine and choose recovery mode (not mandatory but it’s better)
• Run the command

  # vgrename actualName NewName
  

• Edit /etc/fstab and change all the entries with the new name
• Edit /boot/grub/grub.cfg and replace all the old name with the new one
• Edit /etc/initramfs-tools/conf.d/resume and replace the old name with the new one
• Rebuild an initramfs:

  # update-initramfs -u -k all

• Reboot
