zpool-checkpointcheck-point current ZFS storage pool state

zpool checkpoint [-d [-w]] pool

Checkpoints the current state of pool , which can be later restored by zpool import --rewind-to-checkpoint. The existence of a checkpoint in a pool prohibits the following zpool subcommands: remove, attach, detach, split, and reguid. In addition, it may break reservation boundaries if the pool lacks free space. The zpool status command indicates the existence of a checkpoint or the progress of discarding a checkpoint from a pool. zpool list can be used to check how much space the checkpoint takes from the pool.

, --discard
Discards an existing checkpoint from pool.
, --wait
Waits until the checkpoint has finished being discarded before returning.
