14.11.3. Stopping and Deleting Storage Pools

The pool-destroy pool-or-uuid stops a storage pool. Once stopped, libvirt will no longer manage the pool but the raw data contained in the pool is not changed, and can be later recovered with the pool-create command.
The pool-delete pool-or-uuid destroys the resources used by the specified storage pool. It is important to note that this operation is non-recoverable and non-reversible. However, the pool structure will still exist after this command, ready to accept the creation of new storage volumes.
The pool-undefine pool-or-uuid command undefines the configuration for an inactive pool.
