ZFS (Linux) Dataset Size Issue

[402blownstroker]

I am running the latest ZFS for Linux on Fedora 19 x86_64. I am seeing an issue with a dataset between the output of df and du. 'df' shows the data is about 196GB while du reports around 124GB. This was after deleting a bunch of unused data. It seems like the 'df' usage never went down after the delete.

Has anyone else seen this? Since ZFS is handlign the 'filesystem' for the dataset, is 'df' in the dark for what ZFS is doing or is ZFS reporting the wrong info to it?

Do you have snapshots that still contain the deleted data?
Please post the output of "zfs list -r -t all" (in CODE tags).
