Configuration of Enhanced Instance Creation with NetApp FAS for iSCSI or Fibre Channel

The following checklist provides the steps necessary for configuration of Enhanced Instance Creation with NetApp FAS (ONTAP) for iSCSI or Fibre Channel:

1) Configure internal tenant settings in cinder.conf

Review Cinder's Image-Volume cache reference: (http://docs.openstack.org/admin-guide/blockstorage-image-volume-cache.html.)

Obtain the cinder_internal_tenant_project_id:

# openstack service list
+----------------------------------+-------------+----------------+
| ID                               | Name        | Type           |
+----------------------------------+-------------+----------------+
| 468a57b3acd24aaaa41d65efd38cf9b3 | cinder      | volume         |
| 6763e676132f4aaabb68cc1517b18d38 | cinderv3    | volumev3       |
| 68c02f549aff48a8bd1a217af2acaf3d | cinderv2    | volumev2       |
| c4d4d6fad70842159e85927aba7b51f4 | glance      | image          |
| da0958b746ad43e5844c09de23aae2b1 | keystone    | identity       |
| ea78b41d174b4476be6d6bf6cc3c081c | neutron     | network        |
| f030c2914d77496c8dfc8c58acd0d833 | nova        | compute        |
+----------------------------------+-------------+----------------+
            

Edit cinder.conf to contain the following entry in the DEFAULT stanza:

[DEFAULT]
...
cinder_internal_tenant_project_id=6763e676132f4aaabb68cc1517b18d38
...
            

Obtain the cinder_internal_tenant_user_id:

# openstack user list
+----------------------------------+----------+
| ID                               | Name     |
+----------------------------------+----------+
| 6275bf0ad03743949f7d8752464e30e5 | admin    |
+----------------------------------+----------+
            

Edit cinder.conf to contain the following entry in the DEFAULT stanza:

[DEFAULT]
...
cinder_internal_tenant_user_id=a05232baaeda49b589b11a3198efb054
...
            

2) Configure Image-Volume cache settings in cinder.conf

[DEFAULT]
...
image_volume_cache_enabled = True
...
            

3) Change glance_api_version in cinder.conf

[DEFAULT]
...
glance_api_version = 2
...
            

4) Restart Cinder services

# systemctl restart openstack-cinder-{api,scheduler,volume}
            

5) Upload a Glance image

The following command uses an image that is publicly available. Please use the image you prefer and replace the URL accordingly.

# wget https://s3-us-west-2.amazonaws.com/testdrive-bucket/images/trusty-server-cloudimg-amd64-disk1-nfs-edit.img | glance image-create --name=ubuntu-nfs-image --container-format=bare --disk-format=qcow2 --file=trusty-server-cloudimg-amd64-disk1-nfs-edit.img –-progress
            

6) Boot from Cinder

# nova boot --flavor m1.medium --key-name openstack_key --nic net-id=replace-with-neutron-net-id --block-device source=image,id=replace-with-glance-image-id,dest=volume,shutdown=preserve,bootindex=0,size=5  ubuntu-vm
            

7) Verify functionality

Please open /var/log/cinder/volume.log and look for a message similar to the following to confirm that the image-volume was cached successfully:

...
