Creating Datasets

After a storage pool is created, but before data can be store on the pool, you will need to create a dataset. A dataset in TrueNAS is like a folder on a hard drive. Once a dataset is created, you can share it out via NFS, SMB, etc, and apply custom ACL (access permissions) to it.

Creating Dataset

Login to the TrueNAS WebGUI.

TrueNAS will prompt you for confirmation. Type in the name of the dataset, check Confirm, and then you can Delete Dataset.

Once a dataset is deleted, the data on the dataset is gone forever! Make sure you are 100% sure before deleting a dataset, or have a backup ready and verified before deleting.
