Can no longer make snapshots!

[Poppa]

So ever since today when I try to create a snapshot, I get an error window with lots of text. Any idea what is going on?

cannot create snapshot 'Music/Music/Electronic_experimental@manual-20171004': dataset already exists

It appears you already have a snapshot with that name.

Try running zfs list -t snapshot | grep Music/Music/Electronic_experimental@manual-20171004 and see if you get anything return.
