Floating IPs

You can create and pair floating IPs using the command line interface (CLI) or the web interface. For more information about floating IPs and how they are used in the StorONE system, see Floating IPs.

Creating a floating IP for NAS or object store

Before you can create a NAS server or an object store, you must create a floating IP. For replicated NAS and object store virtual storage containers (VSCs, also referred to as volumes), you can also use floating IPs to allow you to access the replicated volume using the same IP address or DNS name, regardless of which system is hosting the primary volume.

Web UI

In the admin web interface, go to Inventory admin > Floatingips admin. Click the Create button, and fill in the sections:

Name

In the Name section, specify the name of the floating IP. This is the name you will use to reference this floating IP within the StorONE user interfaces.

If this floating IP will be used for non-replicated NAS or object store volumes, consider including a variation of nas, object, or s3 within the name for easy identification.

IP Address

Specify the IP address of the floating IP, and select the correct subnet mask. Then, optionally specify the default gateway if this address will be accessible from other subnets.

Interfaces per Node

Select the network interface on each node that will be associated with this floating IP. These are the interfaces that will be assigned the floating IP, depending on which node is active for the NAS server or object store.

For a standby floating IP that will paired with a replication source, these are the interfaces that the floating IP will be assigned to in a replication transition event, again based on which node is active for the NAS server.

After completing all fields, click Submit to create the floating IP.

CLI

To create a floating IP, use the following command:

floatingips create <name> |(--address=<ip> --mask=<subnet> [--gateway=<ip>]) --nodes=<text...> --interfaces=<text...>

<name>

Specify the name of the floating IP. This is the name you will use to reference this floating IP within the StorONE user interfaces.

If this floating IP will be used for non-replicated NAS or object store volumes, consider including a variation of nas, object, or s3 within the name for easy identification.

--address=<ip> --mask=<subnet> --gateway=<ip>

Specify the IP address of the floating IP and the subnet mask. Optionally, specify the default gateway if this address will be accessible from other subnets.

--nodes=<node_1 node_2> --interfaces=<node_1_if node_2_if>

Specify the network interface on each node that will be associated with this floating IP. These are the interfaces that will be assigned the floating IP, depending on which node is active for the NAS server or object store.

You can use the TAB key auto-complete to see the available nodes and interfaces. These arguments are positional, meaning that you must list nodes and interfaces in the same order. If you list node A first, you must specify the interface on node A first in the --interfaces arguments.

Examples

  1. To create a floating IP named s1-nas-ip with the IP address and netmask of 172.16.32.64/24, with a gateway of 172.16.32.1 using the sob4-data and soe5-data interfaces on nodes example-s1n1 and example-s1n2, respectively:

    floatingips create s1-nas-ip --address 172.16.32.64 --mask 24 --gateway 172.16.32.1 --nodes example-s1n1 example-s1n2 --interfaces sob4-data soe5-data

  2. To create a floating IP named s1-s3-ip with the IP address 10.10.150.42/255.0.0.0 and no gateway, using interfaces DATA and DATA on nodes storone-n1 and storone-n2, respectively:

    floatingips create s1-s3-ip --address 10.10.150.42 --mask 255.0.0.0 --nodes storone-n1 storone-n2 --interfaces DATA DATA
