How to create a volume on Synology NAS

A storage volume is used to store data on a NAS, such as a Synology enclosure. It’s created atop a storage pool, which is essentially a single collection of drives when running DSM on a NAS with multiple drive bays. This guide will run you through volumes on a Synology NAS and how to create and manage them.

How to create a volume on a Synology NAS

It’s easy to create a volume and start storing data. A single storage pool can have more than one volume and they can differ in size. For instance, a 2 TB storage pool could have four volumes with different capacities. The minimum capacity of a volume needs to be at least 10 GB. Here’s how to create a volume within Synology DSM:

  1. Sign into your Synology NAS.
  2. Open Storage Manager.
  3. Go to Storage.
  4. Click Create.
  5. Select Create Volume.
  6. Choose the storage pool where the volume will be attached to.
  7. Allocate the desired capacity of the pool for the volume.
  8. Select the desired file system. (I recommend choosing Btrfs.)
  9. Click Next.
  10. Click Apply.

The NAS will now create a volume on the selected storage pool using your desired file system. Before storing any data on the volume, a Shared Folder will need to be created. Data volumes can be expanded in size but they cannot be shrunk so it’s always a better idea to create small and increase in size over time.

How to create an encrypted volume on a Synology NAS

There’s an easy way to create an encrypted volume on a Synology NAS to help safeguard data from unauthorised access. It’s possible to encrypt each volume through DSM with a separate key, which has to be used to gain access and is stored in the encryption key vault. Here’s how to do it:

  1. Sign into your Synology NAS.
  2. Open Storage Manager.
  3. Go to Storage.
  4. Click the Global Settings button.
  5. Under the Encryption Key Vault, select a location to set up the vault. (I’d recommend “local” unless you have another Synology NAS to store the vault.)
  6. Click Save.
  7. Back on the Storage screen, click Create.
  8. Select Create Volume.
  9. Choose the storage pool where the volume will be attached to.
  10. Allocate the desired capacity of the pool for the volume.
  11. Select the desired file system. (I recommend choosing Btrfs.)
  12. Check Encrypt this volume.
  13. Click Next.
  14. Click Apply.

As well as the encrypted volume, the Synology NAS will provide a recovery key, which can be used should the vault be unavailable. If you happen to lose access to both methods, the volume will be inaccessible, so keep the recovery key safe!

Warning! Resetting DSM will clear the vault and everything stored within. The recovery key would need to be used to unlock the volume after the OS is reinitialised.

How to delete a volume on a Synology NAS

It’s possible to remove a volume on a Synology NAS in a couple of steps. This is great for when you need to free up space on a storage pool.

  1. Sign into your Synology NAS.
  2. Open Storage Manager.
  3. Go to Storage.
  4. Choose the volume you wish to delete.
  5. Click on the ellipsis icon.
  6. Select Remove.
  7. Click Remove.
  8. Enter your DSM password.
  9. Click Submit.

Warning! Deleting the volume will also delete all the data stored within.
