vgremove - remove a volume group
vgremove [-d|--debug] [-f|--force] [-h|-?|--help] [-t|--test]
  [-v|--verbose] VolumeGroupName [VolumeGroupName...]
vgremove allows you to remove one or more volume groups. If one or more physical
  volumes in the volume group are lost, consider vgreduce --removemissing
  to make the volume group metadata consistent again.
If there are logical volumes that exist in the volume group, a
    prompt will be given to confirm removal. You can override the prompt with
    -f.
See lvm for common options.
  - -f, --force
- Force the removal of any logical volumes on the volume group without
      confirmation.
