Introduction to the Shared File Systems service

Manila is the file share service project for OpenStack. Manila provides the management of file shares for example, NFS and CIFS as a core service to OpenStack. Manila currently works with NetApp, Red Hat storage (GlusterFS) and EMC VNX, as well as on a base Linux NFS or Samba server. There are a number of concepts that will help in better understanding of the solutions provided by manila. One aspect can be to explore the different service possibilities provided by manila.

Manila, depending on the driver, requires the user by default to create a share network using neutron-net-id and neutron-subnet-id (GlusterFS native driver does not require it). After creation of the share network, the user can proceed to create the shares. Users in manila can configure multiple back-ends just like Cinder. Manila has a share server assigned to every tenant. This is the solution for all back-ends except for GlusterFS. The customer in this scenario is prompted to create a share server using neutron net-id and subnet-id before even trying to create a share.

The current low-level services available in manila are:
