I am wondering, why would anyone want to create DataSet instead of Zvol or vice versa?
What you get with a zvol is something that a client machine can mount as if it were a physical storage device. This might be important in some applications, e.g. virtual machines running on clients. However, getting good performance from this type of setup requires more resources on the FreeNAS box, so you only do it if you really need it.I am wondering, why would anyone want to create DataSet instead of Zvol or vice versa?
Fabulous....thank you so much..Now that I think about it some more, the two concepts are essentially orthogonal.
Datasets are used to organize storage. Shares are used to make storage available to (multiple) clients. While a share often corresponds 1:1 to a dataset, this is not necessary.
Conversely, a zvol is by definition an object used to make storage available to a single client.
