Step A: Gather Information - AWS Elemental Delta

This is version 2.3 of the AWS Elemental Delta documentation. This is the latest version. For prior versions, see the Previous Versions section of AWS Elemental Delta Documentation.

Step A: Gather Information

Before you modify a cluster configuration, obtain the following information:

  • The models and IP addresses (or hostnames) for all of the nodes. Note that:

    • The egress nodes can be different models from the leader and secondary nodes.

    • If you have more than one egress node, each node can be a different model.

    Make sure that you know which models are for which role!

  • A list of Ethernet devices (for all egress nodes) and their IP addresses. Keep in mind that the egress nodes handle only management traffic (typically on eth0) and outgoing traffic.

  • A list of Ethernet devices (on all egress nodes) that are bonded and the IP addresses for those bonds.

  • A list of the Ethernet devices (on the egress nodes) that were configured with IP addresses during installation of AWS Elemental Delta. The eth0 device is always configured during installation; other devices may or may not be. You need this information to determine which devices you need to figure in this configuration process and which you can assume are already configured.

  • The IP addresses of remote storage servers (CIFS, NFS or DAVFS) as already set up on the leader and secondary nodes.

  • The user credentials for Amazon (AWS) S3 storage, if applicable.

  • A list of ports that you want to open beyond the ports that AWS Elemental Delta automatically open.

  • The user credentials for users if you are setting up with user authentication.
