CoPilot Disk (Volume) Management

Allocate data disks (volumes) to your Aviatrix CoPilot deployment to be used for expandable storage.

When you initially provision CoPilot (from your cloud service provider), you must add a disk (volume) to be used for CoPilot storage. You are required to add at least one disk (volume) that is an additional disk (on the side) from the 25GB root disk that already comes with CoPilot. You create the data disk (volume) in your CSP account and attach it to your CoPilot instance. During instance provisioning, there is no minimum requirement for the disk/volume you add. You can choose the disk type (volume type) you want. You will be able to add more storage after deployment.

When you newly launch the CoPilot instance, the initial setup process automatically detects the disk/volume you attached during instance provisioning. An add-disk process prompts you to confirm the disk/volume to use and then formats and attaches your disk(s). A logical disk/volume is created from all physical disks (volumes) you added during provisioning. For example, if you launch Copilot and you added two physical disks that are 8G each, CoPilot will form a 16G volume.

The storage you need for CoPilot can increase based on several factors including the number of Aviatrix gateways launched and the type and volume of traffic in your network. When you need more storage, you can add additional disks (volumes) by using the CoPilot > Settings > Resources page (Attach Additional Disk). For instructions, see Add a Disk (Volume) for CoPilot Storage after Deployment. Adding additional disks applies to simple deployments (not clustered deployments).

After you allocate new disks (volumes), you can only increase storage (you cannot decrease storage).

For data disks you already allocated to your CoPilot deployment, you can increase their size. For instructions, see Expand a Disk (Volume) for CoPilot Storage. This applies only to simple deployments (not clustered deployments).

Disk (volume) management for expandable storage became available with the release of Aviatrix CoPilot base image version 1.5.1. To use the expandable storage feature and leverage additional disks/volumes, you must launch a new CoPilot instance from the marketplace based on a CoPilot base image version 1.5.1 or later (Appliance Version 2).

Add a Disk (Volume) for CoPilot Storage after Deployment

Add a data disk (volume) to your Aviatrix CoPilot deployment to be used for expandable storage. Adding additional disks applies to simple deployments (not clustered deployments).

This procedure assumes you have a running CoPilot and want to add more storage (add a data disk/volume) above and beyond the storage you added when you first provisioned the CoPilot instance (from your CSP).

To add a data disk (volume) for CoPilot expandable storage after deployment:

  1. Log in to your CSP account and create the disk (volume) you want to add. Choose the disk type (volume type) that meets your business needs given the size of your environment and performance requirements.

  2. Attach the disk (volume) to your CoPilot instance. Do not reboot the instance (a disk can be dynamically added to an instance on any CSP without rebooting).

  3. After you receive confirmation from the CSP that the disk is attached, log in to CoPilot.

  4. Go to CoPilot > Settings > Resources > Disk Utilization and click Attach Additional Disk. If you do not see the disk (volume) you created in the list, press the refresh icon.

  5. Select the disk/volume you created and click START.

  6. When the process is complete, click FINISH.

Expand a Disk (Volume) for CoPilot Storage

For data disks you already allocated to your CoPilot deployment, increase their size. Increasing the disk size applies to simple deployments (not clustered deployments).

To expand a disk (volume) that is allocated to your CoPilot deployment:

  1. Log in to your CSP account and locate the disk (volume) attached to your CoPilot instance that you want to expand for CoPilot storage.

  2. Increase the size of the disk (volume).

  3. After you receive confirmation from the CSP that the disk is resized, log in to CoPilot.

  4. Go to CoPilot > Settings > Resources.

  5. In the Disk Usage table, expand the tree-pane icon (shown) for the physical volume associated with your resized data disk.

  6. Click the enabled RESIZE button. CoPilot resizes the physical volume to match the size of your expanded disk.

Monitor Data Disk (Volume) Utilization

In the CoPilot > Settings > Resources > Disk Utilization page, CoPilot shows you the following:

  • Disk Usage section

    Shows a chart of database disk used broken down by the top five indices. This shows which indices are currently taking up the most space and the overall amount.

  • Estimated Disk Runway section

    Shows, in general, when the database would become full and how fast it is growing each day. Assuming data retention policies are working properly, it is expected the database will not run out of space since data is deleted regularly per the policies.

  • Data Retention Policy

    Enables you to set data retention policies for the data in CoPilot’s logical disk (volume).

Set Data Retention Policies for the Logical Disk (Volume)

You can set data retention policies for the CoPilot data stored in the logical disk (volume) in CoPilot > Settings > Resources > Disk Utilization.

You can use the Critical Capacity Management setting to configure overall retention for all indices.

If you want the index retention to be longer for individual indices, you can scroll down the list of indices and configure their respective retention policies.

Monitor Daily Size of NetFlow Indices

You can check the daily size of NetFlow indices in your CoPilot storage in the CoPilot > Settings > Resources > Index Management page. If you click the filter icon and type netflow in the value column to create the filter Index Name contains netflow, CoPilot shows the netflow indices and their sizes.
