Creating Replication Groups

The vStor Group Replication feature allows you to create a replication group between multiple vStor servers. This keeps data synchronized across all the vStor servers in the group by replicating snapshots of the volumes.

Group replication provides a simple way to set up and manage replication for multiple volumes. Instead of creating individual replication relationships between volumes on different vStor servers, you can add volumes to a group and efficiently schedule and replicate them together.

Creating a Replication Group

Note. The vStor servers must already have partnerships established before creating a group replication.

To create a new replication group:

1. In the navigation menu, click Replication.

2. Click on Create a Group in the Replication Relationships section.

3. In the popup dialog, enter the following information:

• Name: Enter a name for the replication group.

• Partner: Select the IP address of the partner vStor server.

• Replication Relationship Priority: Select the replication priority.

• (Optional) Remote Pool ID: Enter the Remote Pool ID of the partner server.

• Select Volumes: Select volumes from the dropdown list to add to the group. Only compatible volumes will be listed.

4. Click Save to create the replication group.

Note. You can group only volumes connected to the same Partner IP address.

The selected volumes will be replicated together according to the configured schedule and settings.

Scheduling Group Replication

After creating a replication group, you can configure a schedule for replicating the volumes in the group.

To schedule group replication:

1. In the Replication Relationships section, hover over a replication group and click Schedule.

2. In the popup dialog, configure the replication frequency and schedule.

3. Click Update to save the schedule.

The volumes in the group will now replicate according to the configured schedule.

You can also manually trigger replication for a replication group by hovering over the group and clicking Synchronize.

Additional Group Replication Options

To use additional options, Hover over a replication group and click More Actions (...). It gives you access to the following options:

• Edit: Modify the group name or volumes in the group.

• Ungroup: Remove the group but keep the replication relationships intact.

• Delete: Delete the group and all replication relationships within it.

vStor CLI for Group Replication

To create a new replication group using the vStor CLI, use the following command:

vstor relationship group create --name <name> --partner_id <partner_id> --bandwidth_priority <priority> --remote_pool_id <pool_id> --local_vol_ids <vol_ids>

To update an existing replication group using the vStor CLI, use the following command:

vstor relationship group update --id <id> --name <name> --bandwidth_priority <priority> --remote_pool_id <pool_id> --local_vol_ids <vol_ids>
