Configuration Replication

Introduction

Configuration replication involves copying metadata associated with files on a storage cluster. This metadata controls access to data, as well as failback and replication mappings, schedules, and properties. For detailed information on what is specifically replicated, please refer to the sections for different storage vendors below.

What is Being Copied?

VAST

Configuration replication for VAST covers the following elements:

• Views
• ViewPolicies
• S3 Lifecycle Rules

Qumulo

Configuration replication for Qumulo covers the following elements:

• SMB Shares
• NFS Exports
• Snapshot Policies

How to Start a Configuration Replication Job

This section explains how to start, monitor, and finish configuration replication.

In Eyeglass, these replication tasks are handled as Jobs that run automatically every 5 minutes in the Running Jobs section of the Jobs window, regardless of the vendor.

If you need to manually start a configuration replication or check your system’s readiness, follow the steps below.

Before starting configuration replication, ensure you have:

• A predetermined candidate for configuration replication.
• Access to the Jobs page within Eyeglass.

1. Navigate to the Jobs page within Eyeglass.

2. In the Jobs window, select Job Definitions from the left-hand menu.

3. In the Job Definitions table, navigate to the section relevant to your candidate. All configuration replication jobs are nested under sections that begin with “Configuration Replication.”

4. Our supported storage vendors are organized in the following manner:

   PowerScale OneFS

   • Configuration Replication: Share, Export, Alias replication
   • Configuration Replication: Snapshot Schedules
   • Configuration Replication: Access Zone replication

   VAST

   • Configuration Replication: View replication

   Qumulo

   • Configuration Replication: Replication Relationship

5. Find your specific candidate in the list, then click on the row or checkbox next to it. The row will be highlighted in yellow.

   info

   You can select multiple rows if you want to run several jobs at the same time.

6. Look at the State column in the table. If the state is OK, you can proceed. The State column can show the following statuses:

   • OK: No action needed; the job is ready to run.

   • User Disabled: The job was turned off by a user. To enable it, click Select a bulk action at the bottom right of the Jobs window, then choose Enable/Disable.

   • Warning: This indicates a non-blocking issue that might cause problems if the job runs.

     • To investigate the warning:
       • Go to DR Dashboard.
       • Select the job type from the left-hand menu.
       • In the next screen, find the object associated with the warning and click the value in the DR Failover Status column.
       • In the new window, expand the Eyeglass Configuration Replication Readiness folder.
       • Click the value that appears below to view the warning details in the Additional Status Information section at the bottom of the window.

   • Error: This indicates a blocking issue, meaning the job cannot run until the issue is resolved.

     • If a job failed recently, you can:
       • Click on Running Jobs in the left-hand navigation.
       • Find the failed job in the resulting table.
       • Click on the row to view more details.
     • To investigate the blocking error:
       • Go to DR Dashboard.
       • Select the job type from the left-hand menu.
       • In the next screen, locate the object associated with the error and click the value in the DR Failover Status column.
       • In the new window, expand the Eyeglass Configuration Replication Readiness folder.
       • Click the value that appears below to view the error details in the **Additional Status

   • Pending: The job is waiting in the queue to run.

   • Policy Disabled: The configuration replication job was turned off on the host cluster. Go to the host cluster and enable it to change this status.

7. To start the configuration replication job, click the three arrows icon next to the job’s status. This will run the job immediately. If you’ve selected multiple rows, click the Select a Bulk Action button at the bottom right of the window, then choose Run Now from the menu. Once the job(s) have been successfully submitted, a confirmation message will appear.

   

How to Monitor a Configuration Replication Job

1. To monitor the progress and status of the job, go to the Running Jobs section in the left-hand menu of the Jobs window.

2. If the job completes successfully, you’ll see a checkmark in the State column. If a red X appears, check the Job Details section to find and resolve the error.
