View replication details

The following table describes the different states in a volume replication:

Transfer status (mirrorState) Overall state
Preparing The volume replication is created and the initial replication operation begins and is in progress.

The amount of transferred data displays in Google Cloud console. Status updates occur in five minute increments.
Mirrored The volume replication is created and the volume replication operation is completed.
Transferring The volume replication is created and an incremental replication operation is in progress. The amount of transferred data displays in Google Cloud console. Status updates are provided in five-minute increments.
Stopped The volume replication was stopped by the user, which allows the destination volume to become writeable.

The size of the destination volume is set independent of the source volume. This state is required if you want to permanently delete a volume replication relationship.

Use the following instructions to view replication details of the source or destination volume using either the Google Cloud console or Google Cloud CLI.

Console

  1. Go to NetApp Volumes pagein the Google Cloud console.

    Go to NetApp Volumes

  2. Click Volumes.

  3. Click the name of the source or destination volume.

  4. Select the Replication tab.

    If the volume is part of a replication, details of the replication appear.

Google Cloud console displays the names of the source and destination volumes. The partner volume's name appears as a clickable link which directs you to its volume details page. For cross-project replication, the link to the partner volume doesn't work. You need to navigate to the partner volume manually.

gcloud

View the details of a replication using the following command:

  
gcloud  
netapp  
volumes  
replications  
list  
 \ 
  
--project = 
 PROJECT_ID 
  
 \ 
  
--location = 
 LOCATION 
  
 \ 
  
--volume = 
 VOLUME_NAME 

Replace the following information:

  • PROJECT_ID : the name of the project your volume is in.

  • LOCATION : the location of the source or destination volume.

  • VOLUME_NAME : the name of the source or destination volume.

For more options, see Google Cloud SDK documentation on volume replication .

Edit a volume replication

You can change the replication schedule of the source volume in a replication relationship.

Use the following instructions to edit replication details in the Google Cloud console:

  1. Go to NetApp Volumespage in the Google Cloud console.

    Go to NetApp Volumes

  2. Click Volumes.

  3. Click the source volume. The Details pageappears.

  4. Select the Replication tab.

  5. Select Edit replication.

  6. In the Edit replicationdialog, update the replication schedulefield.

  7. Click Save.

Delete a volume replication

When you delete a replication, it removes the replication relationship between the source and destination volume. After the replication deletes, both volumes continue to exist independently with the current data they contain.

Considerations

When you delete a replication, NetApp Volumes also deletes the common replication snapshots of source and destination volume. You can't resume a replication relationship for the two volumes again but you can create a new replication with either of them. When you create a new replication, it creates a new destination volume as part of the process.

Delete a replication

Use the following instructions to delete a replication using the Google Cloud console:

  1. Go to NetApp Volumespage in the Google Cloud console.

    Go to NetApp Volumes

  2. Click Volumes.

  3. Click the name of the volume you want to delete.

    The Detailspage appears.

  4. Select the Replicationtab.

  5. Make sure that the Replication statusis set to Stopped. For instructions about how to stop a replication, see Stop a replication .

  6. Click Delete volume replication.

  7. In the Delete volume replicationdialog, enter the name of the destination volume.

  8. Click Delete.
