Volume

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

Management and Operations

Using the feature buttons, you can perform the following operations:

Create: Create a new volume.

Edit: Modify the volume settings.

Delete: Delete an existing volume, which will remove all data stored in it.

Settings: Set thresholds for storage capacity warnings.

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 disk space usage.

Format: Format the volume to another file system without deleting it.

Usage Details: View the volume's usage information.

SSD TRIM: Clear invalid data to optimize the volume’s performance.

Note

1. File system defragmentation and compression are only available for volumes formatted with BTRFS.
2. Higher compression levels increase compression ratio but may reduce data transfer speed. The effectiveness of file system compression depends on file type, performance, and compatibility.
3. SSD TRIM is only available if the volume’s storage pool is composed entirely of SSDs.

How to Create a Volume

1. Ensure that there is an available storage pool with assignable space on your TNAS.
2. Click the "Create" button and choose based on your needs:
 • Create the volume on an existing storage pool.
 • Create the volume on a new storage pool, selecting disks and the type of storage pool to create.
3. Assign capacity to the new volume. The minimum allocation for a volume is 10 GB.
4. Check whether to enable the "HyperLock-WORM File System".
5. Choose the volume’s file format, either BTRFS or EXT4.
6. Click "Confirm" to complete the setup.

HyperLock-WORM File System

HyperLock-WORM is a Write Once Read Many (WORM) file system suitable for storing sensitive data or files that cannot be modified due to compliance regulations.

Enterprise Mode: Data is protected for a certain period after writing and cannot be modified or deleted during this time.

Compliance Mode: Data is permanently protected once written, ensuring integrity and authenticity.

Note

1. HyperLock-WORM volumes can only be created starting from the second volume; the first volume cannot be a HyperLock-WORM volume.
2. HyperLock-WORM volumes cannot be deleted, and the corresponding storage pool cannot be deleted either.
3. Files/folders on a HyperLock-WORM volume cannot be modified during the protection period.
4. The capacity and protection period of a HyperLock-WORM volume can only be increased, not decreased.
