Volume

Volumes are basic storage spaces on which the user may create shared folders, iSCSI LUN (regular file), save data, or install packages. Before creating any volumes, please make sure you have already created a RAID Group. For more information regarding RAID Groups, please refer to RAID Group.

To create a volume:

  1. Make sure your DiskStation has an existing RAID Group with allocatable space.
  2. Click the Create button.
  3. Choose a RAID Group on which to create the volume.
  4. Modify desired settings.
  5. Set the size allocation for the volume. (Setting size allocation is unavailable with volumes created on RAID Group for Single Volumes or iSCSI LUN.)
  6. Click the Apply button to confirm settings.

Note:

To remove a volume:

  1. Select the volume you want to remove.
  2. Click the Remove button and follow the wizard to complete the process.

Note:

To force mount a volume:

If the cache on a volume is missing, the system will not mount the volume when booting up. If the cache is not recoverable, and you want to access the volume, you can click Force mount.

Note:

To repair a volume:

If volume status reads Degraded, please go to the RAID Group tab, and find the appropriate RAID Group. Then follow the suggested instructions to repair it.

To expand the size of a volume

Note:

If volumes are used as replicated targets of Snapshot Replication, the replication performance can be improved by adjusting the settings of Record file access time frequency in the Edit window after volumes are created:

SSD TRIM

If a volume consists entirely of SSDs (Solid State Drives), we recommend enabling SSD TRIM. This feature improves the read and write performance of volumes created on SSDs, increasing efficiency as well as extending the lifetime of your SSDs.

To enable SSD TRIM:

  1. Open Storage Manager and go to Volume.
  2. Select a volume that consists entirely of SSDs, and then click the button Configure.
  3. In the window that appears, go to the SSD TRIM tab, and check the box Enable TRIM.
  4. Click the button Set schedule to choose when the system will perform SSD TRIM.
  5. Click OK.

Note:

File System Scrubbing*

File system scrubbing is a data maintenance feature that inspects volumes. If any data inconsistent with the checksum is detected, the file path will be recorded in Log Center, and it is recommended you use a backup to repair the data.

We recommend regularly performing file system scrubbing to ensure data consistency.

To perform file system scrubbing:

  1. Open Storage Manager and go to Volume.
  2. Select the volume on which to perform file system scrubbing.
  3. Click Manage.
  4. Select File system scrubbing.

Note:

File System Defragmentation*

If your data is modified constantly, the amount of fragmented files will increase in the file system, resulting in slow access performance of files on the drives. Performing file system defragmentation can improve the performance.

To perform file system defragmentation:

  1. Open Storage Manager and go to Volume.
  2. Select the volume on which to perform file system defragmentation.
  3. Click Manage.
  4. Select File system defragmentation.
