The OpenStack Shared File Systems service (manila) provides coordinated access to shared or distributed file systems. The method in which the share is provisioned and consumed is determined by the Shared File Systems driver, or drivers in the case of a multi-backend configuration. There are a variety of drivers that support NFS, CIFS, HDFS, GlusterFS, CEPHFS and other protocols as well.
The Shared File Systems API and scheduler services typically run on the controller nodes. Depending upon the drivers used, the share service can run on controllers, compute nodes, or storage nodes.
Important
For simplicity, this guide describes configuring the Shared File Systems service to use one of either:
generic
back end with the driver_handles_share_servers
mode
(DHSS) enabled that uses the Compute service (nova),
Image service (glance), Networking service (neutron) and
Block storage service (cinder); or,LVM
back end with driver_handles_share_servers
mode (DHSS)
disabled.The storage protocol used and referenced in this guide is NFS
. As
stated above, the Shared File System service supports different storage
protocols depending on the back end chosen.
For the generic
back end, networking service configuration requires
the capability of networks being attached to a public router in order to
create share networks. If using this back end, ensure that Compute,
Networking and Block storage services are properly working before you
proceed. For networking service, ensure that option 2 (deploying the
networking service with support for self-service networks) is properly
configured.
This installation tutorial also assumes that installation and configuration of OpenStack packages, Network Time Protocol, database engine and message queue has been completed as per the instructions in the OpenStack Installation Tutorial.. The Identity Service (keystone) has to be pre-configured with suggested client environment scripts.
