A TrueNAS dataset is a file system within a data storage pool. Datasets can contain files, directories, and child datasets, and have individual permissions or flags.
Datasets can also be encrypted. TrueNAS automatically encrypts datasets created in encrypted pools, but you can change the encryption type from key to passphrase. You can create an encrypted dataset if the pool is not encrypted and set the type as either key or passphrase.
The Capacity Settings screen allows users to set quotas for the selected dataset and for the selected dataset and any of the child datasets for the selected dataset apart from the dataset creation process.
The settings on the Capacity Settings screen are the same as those in the quota management section on the Add Dataset > Advanced Options screen.
Setting Description Quota for this dataset
Quota for this dataset and all children Enter a value to define the maximum allowed space for the dataset.
The Datasets screen and widgets display information about datasets, provide access to data management functions, indicate the dataset roles, list the services using the dataset, and show the encryption status and the permissions the dataset has in place. The screen focuses on managing data storage including user and group quotas, snapshots, and other data protection measures.
Datasets Screen The Datasets screen displays No Datasets with a Create Pool button in the center of the screen until you add a pool and the first root dataset.
TrueNAS allows setting data or object quotas for user accounts and groups cached on, or connected to the system. You can use the quota settings on the Add Dataset or Edit Dataset configuration screens in the Advanced Options settings to set up alarms and set aside more space in a dataset. See Adding and Managing Datasets for more information.
To manage the dataset overall capacity, use Edit on the Dataset Space Management widget to open the Capacity Settings screen.
TrueNAS allows setting data or object quotas for user accounts and groups cached on, or connected to the system.
User Quotas Screen Select Manage User Quotas on the Dataset Space Management widget to open the User Quotas screen. The User Quotas screen displays names and quota data of user accounts cached on or connected to the system. If no users exist, the screen displays No User Quotas in the center of the screen.
