Hi All,
I am just getting my head around FreeNAS and have run into an odd situation, at least not one I can understand. I'm just starting to test playing around with FreeNAS with an eye to move to using it as my permanent storage solution at home. The problem I have is that I'm testing with a 250GB drive, just a single. And a whole bunch of storage has gone missing over night. I'm sure its something I did but I'm not sure what. What I initially did was create a volume called datapool, using the whole 250GB of space.
Nightly report on day 1.
I stuck data right into this datapool volume.
I then discovered datasets. Not really sure what they were I did some reading and it seemed to be like creating a dataset was the best way to store data rather than directly using volumes. So I created a dataset inside my datapool volume called files to play around.
I then created another dataset inside datapool called mac_dropbox and moved the dropbox data I had been storing from datapool to the mac_dropbox dataset. I did this by just using mv /mnt/datapool/Dropbox /mnt/datapool/mac_dropbox. Everything seemed to go smoothly, so I thought. But you'll notice I had not noticed that suddenly my datapool and datapool/files space had suddenly become 59G.
I noticed this and thought that's odd, maybe it was something to do with the files dataset. So I deleted it. This didn't change anything. My datapool still says that it has 59G space and no change on datapool/mac_dropbox.
What could I have done to do this and how do I possibly undo it? :)
Output from du and zpool below as well.
Any help is appreciated :)

Actually I just ran zfs list and got what I expected.
So what's going on here? :)
