Configure multiple back ends
|
|
============================
|
|
An administrator can configure an instance of Manila to provision shares from
|
|
one or more back ends. Each back end leverages an instance of a vendor-specific
|
|
implementation of the Manila driver API.
|
|
|
|
The name of the back end is declared as a configuration option
|
|
share_backend_name within a particular configuration stanza that contains the
|
|
related configuration options for that back end.
|
|
|
|
Administrators can specify that a particular share type be explicitly
|
|
associated with a single back end by including the extra spec
|
|
share_backend_name with the name specified within the back end configuration
|
|
stanza. When the Manila scheduler receives a provisioning request for a share
|
|
type with this extra spec set, it will fulfill the share provisioning request
|
|
on the specified back end (assuming all other scheduling criteria including
|
|
available capacity are met).
|
|
|
|
Enable multiple back ends
|
|
=========================
|
|
To enable multiple share back ends, you must set the enabled_share_backends
|
|
flag in the manila.conf file. This flag defines the names (separated by a
|
|
comma) of the configuration stanzas for the different back ends: one name is
|
|
associated to one configuration group for a back end.
|
|
|
|
The following example shows five configured back ends::
