Not sure if anyone has seen or tried this. I have no relationship with the owner, I just happened to run across it in a web search.
Site still says its in early beta but it works great. Been using it a few months. All ZFS needs is point and click creation/listing, which this webmin module does. I have not tested all the snapshot, clone, revert options. But for creating and listing current pools, its great so far. ZFS commands are simple but this makes its even easier.
Create a pool/file system, mount point, turn on compression if you wish. Done.
