If you're using LVM, you can do "vgchange -Q" to quiesce a volume group. But this doesn't mean that you get self-consistent snapshot. Suppose that a transaction is is progress... you might quiesce the volume group in the middle of the transaction. This objection appies to the pausing technique too.

vgremove
VGREMOVE(8) System Manager's Manual VGREMOVE(8)
NAME
vgremove - remove a volume group
SYNOPSIS
vgremove [-d|--debug] [-f|--force] [-h|-?|--help] [--noudevsync] [-t|--test] [-v|--verbose] VolumeGroupName [VolumeGroupName...]
DESCRIPTION
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.
OPTIONS
See lvm for common options.
-f, --force
Force the removal of any logical volumes on the volume group without confirmation.
--noudevsync
Disable udev synchronisation. The process will not wait for notification from udev. It will continue irrespective of any possible
udev processing in the background. You should only use this if udev is not running or has rules that ignore the devices LVM2 cre-
ates.
