In this section, we use the Manila CLI to verify that the configuration presented in the section called “manila.conf” has been properly initialized by Manila.

In this section, we create a variety of Manila Share Types that leverage both the default capabilities of each driver, as well as the NetApp specific extra specs described in Table 6.9, “NetApp supported Extra Specs for use with Manila Share Types”.
- The
generaltype provisions Manila shares onto the cDOT backend using all the default settings. - The
flashtype provisions Manila shares onto any pool that contains SSD disks within the aggregate. - The
archivetype provisions Manila shares onto any pool that contains SAS drives within the aggregate, and also creates thin provisioned FlexVol volumes. - The
defaulttype provisions Manila shares onto any pool of any driver without share server management.

We'll now look at the CLI output from the Data ONTAP cluster to see what FlexVol volumes were created for the Manila share objects, as well as the provisioning strategy (thin or thick) for each share. Note how the name of the FlexVol volume corresponds to the share UUID as defined by Manila.
You can see that share e4774a70_3e70_4a7c_ab76_886f010efe0a was thin provisioned, as declared by the archive share type. The rest of the shares were thick provisioned. Also note that the share of type myFlash failed to create, as this SVM does not have any aggregates with SSD drives, as seen in the command output below.

In this section, we use the admin-only manage command to bring storage resources under Manila management.
A share is a Data ONTAP FlexVol, and we must tell Manila which host, backend and pool contain the FlexVol.
It may be useful to list the Manila pools to get the correct format. Also note that the FlexVol must be
specified in the format Manila uses to report share export locations.
For NFS this format is address:/path, where address is that of any NFS LIF where the FlexVol is accessible and path is the junction path of the FlexVol.
For CIFS this format is \\address\name, where address is that of any CIFS LIF where the FlexVol is accessible and name is the name of the FlexVol.

Next we'll create two CG snapshots of the new consistency group.

Finally we'll create a new CG from one of the CG snapshots we created above.

In this section, we'll create and work with share replicas. First we'll create a share type that supports replication.
$ manila type-create replication false +----------------------+--------------------------------------+ | Property | Value | +----------------------+--------------------------------------+ | required_extra_specs | driver_handles_share_servers : False | | Name | replication | | Visibility | public | | is_default | - | | ID | ce1709ef-0b20-4cbf-9fc0-2b75adfee9b8 | | optional_extra_specs | snapshot_support : True | +----------------------+--------------------------------------+ $ manila type-key replication set replication_type=dr
Next we'll create a share.

When a share is created with a share type that has the replication_type extra spec, it will be treated as the primary/'active' replica. Let's list the replicas.
$ manila share-replica-list --share-id f49d7f1f-15e7-484a-83d9-5eb5fb6ad7fc +--------------------------------------+-----------+---------------+--------------------------------------+-------------------------------------+-------------------+----------------------------+ | ID | Status | Replica State | Share ID | Host | Availability Zone | Updated At | +--------------------------------------+-----------+---------------+--------------------------------------+-------------------------------------+-------------------+----------------------------+ | 11265e8a-200c-4e0a-a40f-b7a1117001ed | available | active | f49d7f1f-15e7-484a-83d9-5eb5fb6ad7fc | openstack2@cmodeSSVMNFS#aggr3 | nova | 2016-03-23T18:16:34.000000 | +--------------------------------------+-----------+---------------+--------------------------------------+-------------------------------------+-------------------+----------------------------+
Next we'll create a replica of the share.
$ manila share-replica-create f49d7f1f-15e7-484a-83d9-5eb5fb6ad7fc +-------------------+--------------------------------------+ | Property | Value | +-------------------+--------------------------------------+ | status | creating | | share_id | f49d7f1f-15e7-484a-83d9-5eb5fb6ad7fc | | availability_zone | None | | created_at | 2016-03-23T18:19:13.712615 | | updated_at | None | | share_network_id | None | | share_server_id | None | | host | | | replica_state | None | | id | b3191744-cee9-478b-b906-c5a7a3934adb | +-------------------+--------------------------------------+ manila share-replica-show b3191744-cee9-478b-b906-c5a7a3934adb +-------------------+--------------------------------------+ | Property | Value | +-------------------+--------------------------------------+ | status | available | | share_id | f49d7f1f-15e7-484a-83d9-5eb5fb6ad7fc | | availability_zone | nova | | created_at | 2016-03-23T18:19:13.000000 | | updated_at | 2016-03-23T18:19:23.000000 | | share_network_id | None | | share_server_id | None | | host | openstack2@cmodeSSVMNFS2#aggr4 | | replica_state | out_of_sync | | id | b3191744-cee9-478b-b906-c5a7a3934adb | +-------------------+--------------------------------------+
Now we will list the replicas for the share. As you can see, the active replica is located on the pool 'openstack2@cmodeSSVMNFS#aggr3' and the new replica is located on 'openstack2@cmodeSSVMNFS2#aggr4'. The new replica has a replica state of 'out_of_sync', this means that the share data has not been synchronized within the replication window, which is one hour for the cDOT driver.
$ manila share-replica-list --share-id f49d7f1f-15e7-484a-83d9-5eb5fb6ad7fc +--------------------------------------+-----------+---------------+--------------------------------------+-------------------------------------+-------------------+----------------------------+ | ID | Status | Replica State | Share ID | Host | Availability Zone | Updated At | +--------------------------------------+-----------+---------------+--------------------------------------+-------------------------------------+-------------------+----------------------------+ | 11265e8a-200c-4e0a-a40f-b7a1117001ed | available | active | f49d7f1f-15e7-484a-83d9-5eb5fb6ad7fc | openstack2@cmodeSSVMNFS#aggr3 | nova | 2016-03-23T18:16:34.000000 | | b3191744-cee9-478b-b906-c5a7a3934adb | available | out_of_sync | f49d7f1f-15e7-484a-83d9-5eb5fb6ad7fc | openstack2@cmodeSSVMNFS2#aggr4 | nova | 2016-03-23T18:19:23.000000 | +--------------------------------------+-----------+---------------+--------------------------------------+-------------------------------------+-------------------+----------------------------+
Manila checks the status of a replica based on the replica_state_update_interval configuration option. If we wait a short while, the replica will become in sync. If the replica does not become in-sync, refer to the section called “Common Problems”.
$ manila share-replica-list --share-id f49d7f1f-15e7-484a-83d9-5eb5fb6ad7fc +--------------------------------------+-----------+---------------+--------------------------------------+-------------------------------------+-------------------+----------------------------+ | ID | Status | Replica State | Share ID | Host | Availability Zone | Updated At | +--------------------------------------+-----------+---------------+--------------------------------------+-------------------------------------+-------------------+----------------------------+ | 11265e8a-200c-4e0a-a40f-b7a1117001ed | available | active | f49d7f1f-15e7-484a-83d9-5eb5fb6ad7fc | openstack2@cmodeSSVMNFS#aggr3 | nova | 2016-03-23T18:16:34.000000 | | b3191744-cee9-478b-b906-c5a7a3934adb | available | in_sync | f49d7f1f-15e7-484a-83d9-5eb5fb6ad7fc | openstack2@cmodeSSVMNFS2#aggr4 | nova | 2016-03-23T18:27:57.000000 | +--------------------------------------+-----------+---------------+--------------------------------------+-------------------------------------+-------------------+----------------------------+
Finally, let us failover to our other replica.
