later restored by
zpool import

boundaries if the pool lacks free space. The zpool

zpool list command reports
how much space the checkpoint takes from the pool.
-d,
--discard- Discards an existing checkpoint from pool.
-w,
--wait- Waits until the checkpoint has finished being discarded before
returning.
