How to add a storage pool on TrueNAS SCALE


You must configure a storage pool and dataset to store data on your TrueNAS SCALE system. The OS is great for storing lots of data and to do so you’ll need a dataset or few, depending on what you plan on storing and who will be accessing the NAS. Whether setting up a NAS for personal use or a bustling office, this guide will set you on the right path.

TrueNAS Scale is a powerful operating system for running a home or office NAS. You can easily deploy apps and services, store data, and manage multiple user accounts.

Adding a TrueNAS SCALE dataset

This guide assumes you haven’t created a storage pool or dataset yet.

  1. Log into TrueNAS SCALE.
  2. Go to Storage.
  3. Click Create Pool.
  1. Enter a name for the dataset.
  2. Click Next.
  1. Choose a layout (RAID).
  2. Select disk size under “Automated Disk Selection.”
  3. Click Save and go to review.
  1. Confirm the dataset configuration and click Create pool.

You’ll be greeted by the Storage dashboard within TrueNAS SCALE, confirming the pool and dataset have successfully been created. Now you can store data and configure the NAS environment to open access to other devices.

With a dataset loaded on TrueNAS SCALE, it’s possible to configure the dataset with new children, edit the dataset itself (name, case sensitivity, and share type cannot be altered), change permissions, alter user quotas, and delete the dataset.

How to edit dataset quotas

TrueNAS SCALE lets you define the maximum allowed space for the dataset. A defined amount of pool space can be reserved to help prevent situations where automatically generated files can consume the majority of available disk space. Quotas can be configured for new or existing datasets.

  1. Go to Datasets.
  2. Click Manage user quotas.
  3. Click Add.
  1. Add “user data quota” and “user object quota” amounts. (Entering 0 equates to unlimited.)
  2. Add a user or group to apply the quota.

Users will now be restricted by the set quota. Editing quotas is the same process.
