Multi-storage configuration

The Shared File Systems service can provide access to one or more
file storage back ends. In general, the workflow with multiple back ends
looks similar to the Block Storage service one.

Using manila.conf, you can spawn multiple share
services. To do it, you should set the enabled_share_backends flag in the
manila.conf file. This flag defines the comma-separated
names of the configuration stanzas for the different back ends. One name
is associated to one configuration group for a back end.

The following example runs three configured share services:

[DEFAULT]
enabled_share_backends=backendEMC1,backendGeneric1,backendNetApp

[backendGeneric1]
share_driver=manila.share.drivers.generic.GenericShareDriver
share_backend_name=one_name_for_two_backends
service_instance_user=ubuntu_user
service_instance_password=ubuntu_user_password
service_image_name=ubuntu_image_name
path_to_private_key=/home/foouser/.ssh/id_rsa
path_to_public_key=/home/foouser/.ssh/id_rsa.pub

[backendEMC1]
share_driver=manila.share.drivers.emc.driver.EMCShareDriver
share_backend_name=backendEMC2
emc_share_backend=vnx
emc_nas_server=1.1.1.1
emc_nas_password=password
emc_nas_login=user
emc_nas_server_container=server_3
emc_nas_pool_name="Pool 2"

[backendNetApp]
share_driver = manila.share.drivers.netapp.common.NetAppDriver
driver_handles_share_servers = True
share_backend_name=backendNetApp
netapp_login=user
netapp_password=password
netapp_server_hostname=1.1.1.1
netapp_root_volume_aggregate=aggr01

To spawn separate groups of share services, you can use separate
configuration files. If it is necessary to control each back end in a
separate way, you should provide a single configuration file per each
back end.
