Volumes

Volumes are the basic storage spaces of TNAS. All your data (such as shared folders, documents, etc.) is stored in volumes. Before you start storing data on TNAS, you need to create at least one volume.


Management and Operations​

Through the function configuration buttons, you can perform the following operations:

  • Create: Create a new volume.
  • Edit: Edit and modify the volume settings.
  • Delete: Delete an existing volume; all data in the volume will also be completely deleted.
  • Settings: Set the threshold for storage capacity exhaustion alerts.
  • File System Defragmentation: Organize accumulated file fragments in the selected volume to optimize file system performance.
  • File System Compression: Compress the file system to reduce the usage of disk space.
  • Format: Format the volume to another file system without deleting the volume itself.
  • Usage Details: View the usage status of the volume.
  • SSD TRIM: Cleans up invalid data to optimize volume performance.

    • Note
    1. The File System Defragmentation and File System Compression functions are only available when the file system format of the volume is Btrfs.
    2. A higher compression level corresponds to a higher compression ratio, but it will cause a decrease in data transfer speed. The effect of file system compression is affected by file type, performance, and compatibility.
    3. The SSD TRIM function is only available when the storage pool where the volume is located is entirely composed of SSD-type disks.

    How to Create a Volume?​

    1. Confirm that there is a storage pool with allocable space in your TNAS.
    2. Click the "Create" button, and select according to your needs:
     • Create a volume on an existing storage pool.
     • Create a volume on a new storage pool, then select disks and the type of storage pool to create.
    3. Allocate capacity to the new volume; the minimum capacity allocated to a single volume is 10 GB.
    4. Check whether to enable the "HyperLock-WORM File System".
    5. Select the file format for the volume; you can choose Btrfs or ext4.
    6. Click the "Confirm" button to complete the setup.


    HyperLock-WORM File System​

    HyperLock-WORM is a Write-Once, Read-Many (WORM) file system, which can be used to store sensitive data or files that cannot be modified as required by regulations.

  • Enterprise Mode: In this mode, after data is written, it will be protected for a certain period, during which the data cannot be modified or deleted.
  • Compliance Mode: Once data is written in this mode, it will be permanently protected to ensure the integrity and authenticity of the data.

    • Note
    1. Volumes with the HyperLock-WORM file system can only be created starting from the 2nd volume; the first volume cannot be created as a HyperLock-WORM file system volume.
    2. Volumes with the HyperLock-WORM file system cannot be deleted, and the corresponding storage pool also cannot be deleted.
    3. Files/folders in a HyperLock-WORM file system volume cannot be modified during the protection period.
    4. The capacity and protection period of a HyperLock-WORM file system volume can only be increased (not decreased).
