Volumes for Standard

 

Users can create, manage, monitor, create, or delete a logical volume on this page.

 

Note: If you are using QTS 4.1.1 and earlier versions, when connecting the TS-x51/TS-x53 series to a UX-series expansion enclosure you will have to create a separate volume, and the total usable storage capacity is the volume on TS-x51/TS-x53 plus the volume on the UX-series expansion enclosure.

 

Creating new volumes

Follow the steps below to create a new volume:

1.Click "New Volume" to launch the volume creation wizard.
2.Select the enclosure unit, hard disk drive(s), RAID type and hot spare disk for the volume to be created and click "Next".
3.Click "Finish".
4.Please note that all data on the selected hard drive(s) will be erased. Click "Yes" if you are certain about this.
5.The new volume is created.

 

Note: The hot spare disk feature is only available for RAID 1, RAID 5, RAID 6 and RAID 10. For other RAID types, the hot spare disk field will be grayed out.

 

Available volume operations

Click "Actions" and choose to remove a volume, configure the cache settings, format a volume, check the file system of a volume, or rename a volume alias.

 

Note:

All data on a disk will be erased if that disk is formatted. Please use the "Format" feature with caution.
For encryption related options (Change, Download, Save, Lock this Volume), please refer the section on Encryption.
For disk volumes larger than 2TB, it is recommended to format them to the EXT4 file system.
If you have a hot spare drive set up in a RAID configuration, please be sure to manually remove that drive before expanding a RAID Volume or adding a drive to that volume.

 

Expanding volumes

A volume can be expanded through two methods:

1.Creating a new RAID group.
2.Adding new hard drives to an existing RAID group.

 

Expanding volumes by creating a new RAID group

Follow the steps below:

1.Click "Expand Volume" to bring up the Volume Resizing Wizard.
2.Select "Create a new RAID group to expand the available capacity of volume" and click "Next".
3.Select the enclosure unit, hard disk drive(s), RAID type and hot spare disk and click "Next".
4.Please note that if the type of the newly create RAID group is different from that of the existing RAID group(s), the performance of the entire volume could be affected. To continue, click "OK".
5.Click "Expand".
6.Please note that all data on the selected hard drive(s) will be erased. Click "OK" if you are certain about this.
7.The chosen volume is expanded.

 

Expanding Volumes by adding new hard drives to an existing RAID group

Follow the steps below:

1.Click "Expand Volume" to bring up the Volume Resizing Wizard.
2.Select "Adding new hard drive(s) to an existing RAID group", choose an existing RAID group from the drop-down list and click "Next". Please note that RAID 0, RAID 1, Single and JBOD are not supported for volume expansion.
3.Select the hard drive(s) to expand the volume and click "Next".
4.Click "Expand".
5.Please note that all data on the selected hard disk drive(s) will be erased. Click "OK" if you are certain about this.
6.The chosen volume is expanded.

 

Note: To create a volume on the TS-x51 models using an UX-500/800P JBOD, please first create a volume on the NAS and expand the RAID group of the newly created volume from the JBOD's hard drives.

 

 

Volumes for Advanced

 

Users can manage, monitor, create, or delete a logical volume on this page.

 

Note: This feature is applicable to the following Turbo NAS models: TS-269L, TS-269 Pro, TS-469 Pro, TS-469L, TS-469U-RP, TS-469U-SP, TS-470 Pro, TS-470, TS-569 Pro, TS-569L,  TS-669 Pro, TS-669L, TS-670 Pro, TS-670, TS-869 Pro, TS-869L, TS-869U-RP, TS-870 Pro, TS-870, TS-870U-RP, TS-879 Pro, TS-879U-RP, TS-1079 Pro, TS-1269U-RP, TS-1270U-RP, TS-1279U-RP, TS-1679U-RP, TS-EC879U-RP, TS-EC1279U-RP, TS-EC1279U-SAS-RP, TS-EC1679U-RP, TS-EC1679U-SAS-RP, SS-EC1279U-SAS-RP, SS-EC1879U-SAS-RP and SS-EC2479U-SAS-RP, TS-EC880 Pro, TS-EC1080 Pro, TS-EC880U-RP, TS-EC1280U-RP, TS-EC1680U-RP, TS-EC2480U-RP.

 

Creating new volumes

Follow the steps below to create a new volume:

1.Click "New Volume" to launch the volume creation wizard.
2.Select "Quick" (more on the "Custom" option in the following section) and click "Next".
3.Select the enclosure unit, hard disk drive(s), RAID type and hot spare disk for the volume to be created and click "Next".
4.Click "Finish".
5.Please note that all data on the selected hard drive(s) will be erased. Click "Yes" if you are certain about this.
6.The new volume is created.

 

Note: The hot spare disk feature is only available for RAID 1, RAID 5, RAID 6 and RAID 10. For other RAID types, the hot spare disk field will be grayed out.

 

Follow the steps below to create a new, customized volume:

1.Select "Custom". Select to create a new storage pool or from an existing storage pool and click "Next".
2.Configure the volume capacity, thin provisioning, alert threshold, volume alias, encryption and shared folder settings and click "Next".
3.Click "Finish".
4.A new volume is created.

 

Note:

Thin provisioning: This approach can over-allocate the volume capacity for each workgroup regardless of the physical storage limit, and the physical disk space is used only when files are written into the volume. With thin provisioning, the volume space is fully utilized.
Thick provisioning: This approach can instantly allocate physical storage space for the volume. Physical space will be created as soon as the space is allocated for the volume, and that space cannot be used by other volumes.
A thick provisioned volume is usually more efficient for high frequency read/write activities. Because the space has been allocated for the volume, the predicament of insufficient physical space can be avoided, but the use of space is relatively inefficient.

 

Removing volumes

To remove a volume, select a volume to be removed and click "Remove Volume". Click "Apply" and the selected volume is removed.

 

Expanding volumes

Follow the steps below to expand the capacity of a volume.

1.Select a volume to be expanded and click "Expand Volume".
2.Set the capacity for the volume and click "Apply".
3.The capacity of the volume is expanded.

 

Available volume operations

Click "Actions" and choose to configure the cache settings, format a volume, check the file system of a volume, reclaim space for a volume, or encrypt a volume.

 

Note:

All data on a disk will be erased if that disk is formatted. Please use the "Format" feature with caution.
For encryption related options (Change, Download, Save, Lock this Volume), please refer to Encryption.
For disk volumes larger than 2TB, it is recommended to format them to the EXT4 file system.
If you have a hot spare drive set up in a RAID configuration, please be sure to manually remove that drive before expanding a RAID Volume or adding a drive to that volume.

 

Expanding volume capacity

With this function, volume capacity can be expanded by replacing hard disk drives in a RAID group array one by one. This option is supported for the following RAID types: RAID 1, RAID 5, RAID 6 and RAID 10. Follow the steps below to expand a RAID group:

1.Select a RAID group and click "Manage" > "Expand Capacity".
2.Select at least one hard disk drive. After the description displays "Please remove this drive", remove the hard disk drive from the NAS or expansion enclosure.  
3.After the description displays "You can replace this drive", plug in the new hard disk drive to the drive slot. Repeat the same process for all hard drives to be replaced. Click "Expand Capacity" to continue.
4.Click "Yes".  
5.The chosen RAID group is expanded.

 

Adding hard disk drives

With this function, new drive members can be added to a RAID group. This option is supported for the following drive configurations: RAID 5 and RAID 6.

Follow the steps below to add the hard disk drive(s) to a RAID group:

1.Select a RAID group and click "Manage" > "Add Hard Drive".
2.Select hard disk drive(s) from the list to add to the chosen RAID group and click "Apply".  
3.Please note that all data on the selected hard drive(s) will be erased. Click "Yes" if you are certain about this.
4.The chosen hard disk drive(s) are added to the selected RAID group.

 

Migrating RAID configuration

With this function, a RAID configuration can be migrated to a different RAID configuration. This option is supported for the following drive configurations: Migrating single drive to RAID 1; Migrating RAID 1 to RAID 5; Migrating RAID 5 to RAID 6. Please note that some apps need to be installed again (e.g. XDove.) Follow the steps below to migrate a RAID configuration:

1.Select a RAID group and click "Manage" > "Migrate".
2.Select the hard disk drive(s) from the list and click "Apply".
3.Please note that all data on the selected hard disk drive(s) will be erased. Click "Yes" if you are certain about this.
4.The chosen RAID configuration is migrated to the new one.

 

Configuring spare drives

With this function, a spare drive can be added to or removed from a RAID 1, RAID, 5, RAID 6, or RAID 10 configuration. Follow the steps below to configure a spare drive:

1.Select a RAID group and click "Manage" > "Configure Spare Drive".
2.Select the hard disk drive(s) to be configured as spare drive and click "Apply".
3.Please note that all data on the selected hard disk drive(s) will be erased. Click "Yes" if you are certain about this.  
4.The chosen disk drives are added as spare drive.

 

Enabling bitmap/ disabling bitmap

This function can reduce the rebuilding duration after a crash, or time length required to remove/re-add a hard disk. This feature does not improve the disk read/write performance and might even cause a small degradation in performance. However, if an array has a bitmap, a hard disk can be removed and re-added, and only changes in blocks need to be made since the removal (as recorded in the bitmap) can be re-synced. To enable a bitmap, select a RAID group and click "Manage" > "Enable Bitmap" and then "OK". To disable a bitmap, select a RAID group and click "Manage" > "Disable Bitmap" (only available after a bitmap has been enabled) and then "OK".

 

Note: The bitmap support is only available for RAID 1, RAID 5, RAID 6 and RAID 10.

 

Recovering Failed RAID Disk Volumes

This function can recover failed RAID disk volumes from the "Inactive" status to the normal state (RAID 1, RAID 5, RAID 6 and RAID 10 will be recovered to the degraded mode; RAID 0 and JBOD will be recovered to the normal state.) Before recovering a failed disk volume, please confirm that all hard disks of that disk volume are properly seated in the NAS drive bays. Once recovery is completed, back up your data on the disk(s) immediately in case the disk volume fails again.

 

Inactive RAID disk volumes can be recovered only if the minimal number of healthy disks required for the RAID configuration is available on the NAS. For example, in a RAID 5 configuration with three hard disks in the array, at least two healthy hard disk drives are required available in the NAS for volume recovery. If not, this RAID volume cannot be recovered. Refer to the following table for the minimal number of hard disks required to recover each RAID group:

RAID group

Minimal number of hard disks required for recovery

RAID 1

1

RAID 5

Number of disks - 1

RAID 6

Number of disks - 2

RAID 10

Number of disks / 2; (1 hard drive per RAID 1)

 

Follow the steps below to recover a failed RAID group:

1.Select a failed RAID group.
2.Click "Manage" > "Recover".
3.The chosen RAID group is recovered.

 

Configuring Alert Threshold

 

The alert threshold is used to remind users when the capacity of a chosen volume is used up to the specified threshold level. A warning message will pop up when the specified threshold is reached.

To set an alert threshold, select a volume, click "Set Threshold", enter the threshold level and click "Apply". The alert threshold is set.

 

Creating New Shared Folders

 

Follow the steps below to create a new shared folder:

1.Click "Create New Shared Folder".
2.Specify the folder name and description of the new shared folder and select the disk volume for the shared folder.
3.Click "Edit" to the right of "Configure access privileges for users" in Step 2 and specify user privileges.
4.Click "Edit" to the right of "Advanced settings" in Step 2 and configure the guest access right, hidden folder, Oplocks, recycle bin and path. Click "Create".
5.A new shared folder is created.

 

Encryption

 

The disk volumes on the Turbo NAS can be encrypted with 256-bit AES encryption for data breach protection. The encrypted disk volumes can only be mounted for normal read/write access with an authorized password. The encryption feature protects the confidential data from unauthorized access even if the hard drives or the entire NAS were stolen.

 

Note: The AES volume-based encryption is applicable only to specific QNAP NAS models. Please refer to the product comparison table for details.

 

Data encryption on QNAP Turbo NAS

Users can manage the encrypted disk volumes on the NAS. Each encrypted disk volume is locked by a particular key. The encrypted volume can be unlocked by the following methods:

Encryption password: Enter the encryption password to unlock the disk volume. The default password is "admin". The password must be 8-16 characters long. Symbols (! @ # $ % ^ & * ( )_+ = ? ") are supported.
Encryption key file: Upload the encryption key file to the NAS to unlock the disk volume. The key can be downloaded from the "Encryption" page after the disk volume is successfully unlocked.

 

Before you start

Please be reminded of the following before using the data encryption feature of the Turbo NAS.

The encryption feature of the Turbo NAS is volume-based. A volume can be a single disk a JBOD configuration, or a RAID array.
Select whether or not to encrypt a disk volume before it is created on the NAS. In other words, a volume cannot be encrypted after it is created unless the disk volume is initialized. Note that initializing a disk volume will clear all data on the disk.
The encryption on the disk volume cannot be removed without initialization. To remove encryption on the disk volume, the disk volume must be initialized and all the data will be cleared.
Keep the encryption password or key safe. If the password is forgotten or the encryption key is lost, the data cannot be accessed anymore.
Before getting started, read the instructions carefully and strictly adhere to the instructions.

 

Note: The data encryption functions may not be available in accordance to the legislative restrictions of some countries (ex. Russia, Belarus, Ukraine, Kazakhstan and Uzbekistan.)

 

Creating new encrypted disk volumes

To create a new encrypted disk volume on the NAS, follow the steps below:

1.Login the NAS as an administrator. Go to "Storage Manager" and click "New Volume".
2.Select the hard drive(s) you want to configure for the disk volume and the RAID type. Click "Next".
3.Specify the volume details (including the volume capacity, alert threshold and volume alias,) check "Encryption", fill out the encryption password and choose whether to save the encryption key, select to create a shared folder automatically after new volume initialization and fill out the name of the shared folder for the intended volume. Click "Next".
4.Confirm the settings and click "Finish".
5.Note that all the data on the selected drives will be DELETED! Please back up the data before creating the encrypted volume. Click "Yes" after data backup.
6.Click "Actions" > "Encryption" > "Lock this Volume". Click "Yes".
7.An encrypted disk volume is created on the NAS.

 

Encryption key management

To manage the encryption key settings, login the NAS as an administrator and go to "Storage Manager" > "Volumes" > "Actions" > "Encryption".

There are three options to manage the encryption key:

Change the encryption key: Enter your old encryption password and the new password. (Please note that after the password is changed, any previously exported keys will not work anymore. The new encryption key needs to be downloaded if necessary, see below.)
Download the encryption key file: Enter the encryption password to download the encryption key file. With this option, the encryption key can be saved as a file. The file is also encrypted and can be used to unlock a volume, without knowing the real password (see "Locking and unlocking disk volumes manually" below.) Please save the encryption key file in a secure place!
Save the encryption key: Save the encryption key on the NAS to automatically unlock and mount the encrypted disk volume after the NAS restarts.

 

Locking and unlocking disk volumes manually

To lock a volume, login the NAS as an administrator. Go to "Storage Manager" > "Volumes". Select a volume to be locked and click "Actions" > "Encryption" > "Lock this Volume". Click "Yes". To unlock a volume, login the NAS as an administrator, go to "Storage Manager" > "Volumes", select a volume to be unlocked, click "Actions" > "Encryption" > "Unlock this volume". Choose either to enter the encryption password, or use the encryption key file exported previously. Click "Apply". If the encryption password or the key file is correct, the volume will be unlocked and become available.

 

Verifying encrypted disk volumes

To verify that a disk volume is encrypted, login the NAS as an administrator. Go to "Storage Manager" > "Volumes". The encrypted disk volume will be shown on this page, with a lock icon under "Status". The lock will be shown as opened if the encrypted volume is unlocked. A disk volume without the lock icon under "Status" is not encrypted.

 

Behaviors of encrypted volumes upon system reboot

An example is provided to illustrate the behavior of encrypted volumes upon system reboot. In this example, there are two encrypted disk volumes on the NAS:

DataVol1 is created with the option "Save Encryption Key" disabled.
DataVol2 is created with the option "Save Encryption Key" enabled.

 

Note: For details on enabling or disabling the "Save Encryption Key" option, please refer to the section on Encryption Key Management above.

 

After restarting the NAS, check the volume status. DataVol1 is locked, but DataVol2 is unlocked and mounted. Since the encryption key is not saved on DataVol1, the encryption password needs to be manually entered to unlock DataVol1. Please be reminded that by saving the key on the NAS, data will only be protected in case of stolen hard disk drives. However, there is still a risk of data breach if the entire NAS is stolen as the data is  accessible after the NAS is restarted. If the encryption key is not saved on the NAS, the NAS will be protected against data breach even if the entire NAS were stolen. The disadvantage is that the disk volume needs to be manually unlocked each time the system restarts.
