Managing Volumes in Catalogic vStor

In Catalogic vStor, you can create three types of volumes - Filesystem, MinIO, and LUN. Filesystem volumes are used in NAS environments and rely on the server’s backing storage. MinIO volumes use the embedded MinIO server on vStor, and a bucket must be pre-created for this type. LUN volumes are suitable for SAN environments.

Creating a volume using the vStor Web Interface

To add a volume to Catalogic vStor using the vStor Web Interface:

1. Open the vStor Web Interface by connecting to https://<vStor_hostname_or_IP>:8900.

2. Log in as admin.

3. In the navigation menu, click Storage.

4. On the Pools screen, select a pool from the tabbed interface and then click Create Volume.

5. In the Create new Volume dialog:

   • Enter the volume name.

   • Select the type (Filesystem, MinIO, or LUN).

     • For LUN: specify size and unit.

     • For MinIO: input the server port number (range 9000-9100). Ensure a MinIO bucket is already created.

See also. For more details on managing hosts for LUN volumes, see Managing Hosts for LUN Volumes in Catalogic vStor.

Attention! To use MinIO for storage, you need to add a custom certificate to your vStor instance.

6. (Optional) Select the Enable encryption to enable encryption on the volume. Encryption may only be applied to volumes of type Filesystem and Lun.

7. Click OK to add the volume. For Filesystem volumes, set up a share as needed. For details, see Adding a Share to vStor.

Ensure that you can see the new volume in the Volumes table on the Pools screen.

Creating a volume using vStor CLI

To add a volume to Catalogic vStor using vStor CLI:
