Provisioning a multi-node Couchbase VDB

Use the multi-node provisioning workflow when you need to create a Couchbase VDB that spans multiple nodes on the target environment. The Couchbase 2026.1.0 connector supports multi-node provisioning by defining the target node topology, including the primary node and any additional nodes, before you submit the VDB request.

1. Navigate to Manage, and select Datasets.

2. Select the dataset and the snapshot that you want provision from. Click the provision VDB icon to open the provision VDB wizard.

3. Select the target host from the dropdown on which VDB needs to be created.
   

4. Enter the following values for the target configuration:

   • Target Port Number: Port number on which Couchbase services will be started. ( ex. 8091 )

   • Mount Path: NFS mount path where dSource snapshot will be mounted by Engine ( ex. /mnt/provision/targetdemo )

   • Target Cluster name: Cluster name which is required to be set up on the target host. ( ex. targetdemo )

   • Cluster Ram Size: Whole Cluster memory

   • Cluster Index Ram Size: Cluster indexer memory

   • Cluster FTS Ram Size: Cluster FTS memory ( if needed and FTS service will be configured )

   • Cluster Eventing Ram Size: Cluster Eventing memory ( if needed and Eventing service will be configured )

   • Cluster Analytics Ram Size: Cluster Analytics memory ( if needed and Analytics service will be configured )

5. Enter the following values for the target configuration:

   • Target couchbase Admin User: Target Cluster admin username

   • Target couchbase Admin password: Target Cluster admin password

   • Select services needed on the first node of the cluster ( FTS, Eventing, Analytics )

   • Click Add button to open a dialog box for additional node. If you need more nodes, click Add button again to add more nodes.

   • Enter the following values for each node:

     • Delphix Environment Name: Select an additional node environment from the drop-down menu

     • Delphix Environment User: Select an environment user

     • Node hostname / IP: Enter a hostname or IP of the new node - it will be used as a server name in Couchbase configuration

     • node_list: Provide the ordered list of target nodes included in the multi-node cluster configuration. The node list defines the participating nodes for the new VDB and is required when you add additional nodes to the deployment.

     • Select services needed on the additional node of the cluster ( FTS, Eventing, Analytics )

6. Provision connector based VDB. Enter the following value:

   • VDB Name: Delphix Target Cluster name

   • Target group: Delphix Target Cluster group

7. Select a policy for VDB, select Next.

8. Select masking for VDB if needed, select Next

9. Add hooks for VDB if needed, select Next

10. Preview the summary and select Submit

    

Once the VDB is created successfully, you can review the datasets on Manage > Datasets > vdb Name.
