The following instructions setup OpenStack Manila and Cinder (Liberty-based) using PackStack and RDO. RDO is a community of people using and deploying OpenStack on CentOS, Fedora, and Red Hat Enterprise Linux. These instructions are for CentOS7.

Architecture

This exercise will walk you through installing OpenStack on a single server with 3 network interface cards. Clustered Data ONTAP should be setup with a Cluster Management LIF prior to proceeding. Our recommendation is to provision sufficient disk space (100GB or more), memory (16GB or more), and networking (1Gbps or more) for the OpenStack server. The instructions assume the availability of:

· An external network that you can use to SSH to your server and Clustered Data ONTAP.

· A private network that is used for OpenStack instance-to-instance communication. It is not heavily used in this lab guide, but is needed for instance-to-instance communication.

· A storage network on which the Clustered Data ONTAP NFS Data LIFS are located. In our lab, the Clustered Data ONTAP Cluster Management LIF was located on the external network, but it should still be functional if you have it on the Storage Network along with the NFS Data LIF.

You will also step through the deployment of a Neutron router, creation of a Nova instance, setup and use of a Manila share, and setup and use of a Cinder volume.

The architecture is shown below.

Setup Clustered Data ONTAP (CDOT)

Please setup your CDOT with a Cluster Management LIF on the external network before proceeding.

#Login to CDOT using your username and password

[user@local-machine]$ ssh admin@<cluster-mgt-lif-ip-address>

Password: <password>

Example:

$ ssh admin@10.10.10.200

#Create a new vserver (SVM). The name used was “netapp-vs” and aggregate (disk pool) used was “aggr1.” Your aggregate may be different.

The CDOT filer has now been configured for Manila.

OpenStack Server Configuration

Obtain an x86_64 server.

Setup 3 network interface cards on the box.

Ensure it has 16GB of memory, 100GB of disk space, and 1GbE networking.

Install Centos 7 on it. The version installed in the lab was:

CentOS Linux release 7.2.1511 (Core) with GUI

Networking Pre-Configuration

#Login to the server

[user@local-machine ~ ]$ ssh root@<external-network-interface-ip-address>

Password: <password>

#Turn NetworkManager off

[root@stlrx300s7-102 ~ ]$ service NetworkManager stop

[root@stlrx300s7-102 ~ ]$ chkconfig NetworkManager off

#For name resolution, use the following in /etc/resolv.conf

nameserver 8.8.8.8

nameserver 8.8.4.4

nameserver 127.0.0.1

As mentioned previously, there should be 3 interfaces on the CentOS server.

1. Interface1 connects to your LAN is the external interface

2. Interface2 connects to your private network

3. Interface3 connects to your storage network

	Interface 1	Interface 2	Interface 3
ID	enp8s0f0	enp4s0f1	enp4s0f0
IP Address	10.10.10.100	192.168.10.20	172.20.20.100
Network	10.10.10.0/24	192.168.10.0/24	172.20.20.0/24
Description	External Interface	Internal Interface	Storage Network Interface

The initial configuration of each of these interfaces is shown below, please adapt these to suit your networking.

Once the interfaces are configured according to your network infrastructure, please:

· ensure that you can ping other hosts in the external (LAN) and storage networks

· ensure that private network interface is up and configured with an IP address. Use the command ifconfig

You have now setup Manila, created a share and accessed from an OpenStack instance. If your networking is setup to provide access to the storage network (with or without routing), you should also be able to create shares using Manila for clients outside the OpenStack cloud.

Setup Cinder and Create a Volume

On your CDOT, please create a FlexVol volume container, ensuring that your “unix-permissions” and “junction-path” are as shown below. You will use the junction path as the Cinder back end later.

Troubleshooting

PackStack Install: RabbitMQ

PackStack install fails because rabbitmq-server cannot be started.

Ensure that that /etc/hosts and /etc/hostname are similar.

Example:

/etc/hosts

::1 localhost

127.0.0.1 centos7.corp.com centos7

/etc/hostname

centos7

PackStack Install: NetworkManager

PackStack installs fail with NetworkManager errors.

Ensure that NetworkManager is stopped and turned off prior to PackStack install

$ service NetworkManager stop

$ chkconfig NetworkManager off

Commands on Nova, Cinder and Manila fail with “You must provide a user…” ERROR

Please source the keystonerc_admin file if you see the following error when running commands:

ERROR: You must provide a user name through --os-username or env[OS_USERNAME].

$ source ~/keystonerc_admin

$ cinder list

Creating a Nova Instance Error

Nova instances don’t boot and show an ERROR status almost immediately.

The Glance image you’re using may be fetched from an outdated URL. For the latest URLs, please check http://docs.openstack.org/image-guide/obtain-images.html#official-ubuntu-images. In order to try with the new URL, please run the following command with the updated URL:

$ curl <replace-with-updated-image-url> | glance image-create --name=ubuntu-updated --container-format=bare --disk-format=qcow2

Use the ubuntu-updated image in your nova boot command.

$ nova boot --flavor m1.medium --image ubuntu-updated --key-name openstack_key test2

What were the changes made to manila.conf through the install script?

Manila.conf will have a new stanza called ‘netapp’ and this stanza will be enabled using the enabled_share_backends parameter.

Do I need to setup Manila first if I only want Cinder?

No, you don’t need to setup Manila for Cinder. However, in order to setup Cinder, you should setup CDOT first and install OpenStack. To setup only Cinder, your sequence of steps will be:

1. Architecture

2. Setup Clustered Data ONTAP (CDOT)

3. OpenStack Server Configuration

4. Networking Pre-Configuration

5. Install OpenStack Liberty Using Script

6. Setup Neutron Networking

7. Setup Security Group, Glance, Key-Pair, And Ubuntu Instance/VM

8. Setup Cinder and Create a Volume

9. Login to the Ubuntu Instance and Use the Cinder Volume
