Managing Volumes

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; this type requires creating a bucket. LUN volumes are suitable for SAN environments.

Creating a Volume

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. Select a pool and click Create Volume.

5. In the Create new Volume dialog:
   • Enter the volume name. The maximum length is 128 characters.
   • Select the type (Filesystem, MinIO, or LUN).
     • For LUN: specify size and unit.
     • For MinIO: input the server port number (range 9000–9999, excluding 9104 and 9202). Ensure a MinIO bucket is already created.

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 Automatically scan snapshots with GuardMode to enable automatic GuardMode scan.
7. (Optional) Select the Enable volume deletion lock toggle to prevent any modifications or deletions by unauthorized users. For details, see Volume Deletion Lock.

To use deletion protection features, you need to add MFA to your vStor account. For details, see Using Multi-factor Authentication (MFA).

8. (Optional) Select the Enable encryption toggle to enable encryption on the volume. Encryption may only be applied to volumes of type Filesystem and Lun. If encryption is enabled, set an encryption password. Optionally, enable Save key in Encryption Keystore to store the password securely.

To learn more about storing and managing encryption passwords, see Encryption Keystore.

9. Click Save to add the volume. Or go to the Advanced Options section.
   For Filesystem volumes, set up a share as needed. For details, see Managing Shares.

10. Click Save.

Ensure you can see the new volume in the Volumes table on the Pools screen. If you have enabled the deletion lock, your volume will have a shield icon in the volume view.

Attention!

You cannot delete a volume that contains protected snapshots.

Click to expand the Advanced Options section.

Storage Allocation

Assign the Volume quota, which is the maximum size the volume will occupy in the pool. Note that setting this value too low may result in errors reporting not enough space on the volume despite sufficient pool capacity.

Replication Relationship Group

Select an existing group from the dropdown to add the volume to this group. See also Creating Replication Groups. Note that the newly created volume will inherit the replication relationship group’s settings, such as Replication Bandwidth Settings (priority), replication schedule and the target replication pool.

Access Permissions

Select users you want to grant access permissions to the volume. Only standard users will be visible. Users with access permissions to the entire pool where you are creating the volume cannot be selected, as they already have pool-level access.

Migrating a volume between storage pools

To migrate a volume:

1. In Storage, locate a volume you want to migrate.

2. Click More Actions (•••) and select Move to different pool to open the Move to Different Pool dialog window.

3. Select Destination Pool and click Move.

Restrictions.

Volumes with established replication relationships cannot be moved. If you attempt to move such pool, you will be prompted with an error message dialog.

Select Detach to continue or Cancel to cancel. You will be prompted to confirm your decision.

4. Click Yes to confirm. The volume transfer will start. This may take a while.
