Creating a Dataset Setting Dataset Compression Levels Setting Dataset Quotas Changing Dataset Inherited Values Setting Datasets Access Controls Creating a Dataset for a Fusion Pool Managing Datasets Editing a Dataset Editing Dataset Permissions Deleting a Dataset A TrueNAS dataset is a file system within a data storage pool. Datasets can contain files, directories (child datasets), and have individual permissions or flags. Datasets can also be encrypted, either using the encryption created with the pool or with a separate encryption configuration.
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.
Configuring User Quotas Configuring Group Quotas 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.
