I have an issue were snapshots are being created and the drive fills up while the snapshot is being created.  This is particular issue with sabnzbd docker and the pool drive is zfs.  I tried running 'zfs list -H -o name -t snapshot | xargs -n1 zfs destroy -R' to purge all snapshots on the nvme_cache pool but I get message snapshot is cloned.  I want to purge the cloned snapshots what am I missing?

I feel like i should be able to do this and kill all linked snapshots.

Problem may come from the first error, i.e., dataset is busy.
