Reattaching an Existing VJBOD Cloud LUN

  1. Open the VJBOD Cloud app.
  2. Click Create VJBOD Cloud Volume/LUN.

    The Create VJBOD Cloud Volume/LUN window opens.

  3. Click Cloud LUN.

    The Create VJBOD Cloud LUN screen appears.

  4. Select a cloud service.
  5. Configure the selected cloud service.

    Depending on the selected cloud storage provider, you may need to log in, authenticate, or configure settings through a third-party interface.

    For details, see Connecting to a VJBOD Cloud Service.

  6. Optional: Select Use system proxy settings.

    When enabled, VJBOD Cloud connects to the cloud storage space using the system proxy server setting, configured at Control Panel > Network & File Services > Network Access > Proxy.

  7. Click Search.
  8. Select a cloud space.

    This may be a bucket, container, account name, or something else depending on the cloud service provider.


    If you do not have permission to browse the list of cloud spaces, then you need to enter the name of the cloud space manually.

  9. Optional: Click Performance test.

    QTS tests the read and write speeds of the cloud space, and then displays the results with a warning if speeds are too low.

  10. Click Next.
  11. Select Attach an existing cloud LUN.
  12. Select an existing LUN.
  13. Allocate stored space.

    Stored space is space used to store a copy of the LUN's data locally on the NAS.

    1. Select a storage pool.
    2. Specify the capacity of the stored space.




      Minimum stored space capacity

      1.25x the LUN's capacity

      Additional space is needed to store metadata.

      Maximum stored space capacity

      2x the LUN's capacity


  14. Click Next.
  15. Optional: Forcibly disconnect the LUN from its current NAS.

    If a volume is connected to another NAS, then the LUN's status will be Occupied and Current NAS will display an IP address other than Localhost.


    Forcibly disconnecting a LUN deletes the LUN's data from the other NAS, and then recreates the LUN locally from its last restore point. Any changes to data made since the last restore point will be lost.

    1. Specify the admin password of the other NAS.
    2. Click OK.
  16. Optional: Deselect Do not map it to a target for now.

    If deselected, the Edit LUN Mapping wizard appears after QTS has finished creating the LUN.

  17. Review the summary information, and then click Finish.

The VJBOD Cloud LUN appears in the Cloud Storage table at VJBOD Cloud > Overview.
