Solaris 11.4 Beta: Fast (asynchronous) ZFS destroy
A destroy of a larger ZFS filesystem can take some time.
If you would like to destroy and re-create a filesystem, you need to wait till the destroy is done.
This was the case in the past. Solaris 11.4 Beta includes a new feature: It destroys ZFS filesystems asynchronously.
You can thus re-create your filesystem quickly. The destroy runs in the background. Using zpool monitor you see how long the background destroy takes.
