Remove Remote Archive Volume

If a remote archive volume is no longer needed, you can remove it. Removing a remote archive volume will remove the remote source's metadata from EXAStorage. As a result, you cannot run a backup to this volume anymore.

Removing a remote archive volume does not delete any data stored in the remote source.

Prerequisites

A remote archive volume must exist.

Procedure

This procedure is carried out using ConfD.

The ConfD examples are written in Bash on a Linux terminal running the Exasol tool confd_client, which is accessed by connecting to EXAClusterOS on the database nodes using Exasol Deployment Tool (c4). You can also interact with ConfD from an external tool using Python and XML-RPC. For more information, see ConfD.

Placeholder values are indicated with UPPERCASE characters. Replace the placeholders with your own values.

  1. Connect to EXAClusterOS (COS) using c4 connect -t<DEPLOYMENT>/cos. For example:

    c4 connect -t1/cos

    If you do not specify a node, you will normally be connected to the first node in the deployment. If the cluster is configured with an access node, the first node is the access node (usually n10). The COS command prompt indicates which node you are currently connected to. 

    [root@n10 ~]#

    For more information about c4 commands, see Exasol Deployment Tool (c4).

  2. Find the name of the remote archive volume you want to remove using the ConfD job remote_volume_list. If you cannot identify the volume based on the volume name, use remote_volume_info to see the details for a given remote archive volume.

    confd_client -c remote_volume_list

  3. Remove the remote archive volume using the ConfD job remote_volume_remove.

    Replace REMOTE_VOLUME_NAME with the name of the volume you want to remove.

    confd_client -c remote_volume_remove -a 'remote_volume_name: REMOTE_VOLUME_NAME'

Verification

Use the ConfD job remote_volume_list to verify that the volume is no longer present in the list.

confd_client -c remote_volume_list
