 GlusterFS driver

GlusterFS driver uses GlusterFS, an open source distributed file system, as the storage back end for serving file shares to the Shared File Systems clients.

 Supported shared filesystems

  • NFS (access by IP)

 Supported operations

  • Create NFS share.

  • Delete NFS share.

  • Allow NFS share access.

    • only 'rw' access

  • Deny NFS share access.


  • Install glusterfs-server package, version >= 3.5.x, on the storage back end.

  • Install NFS-Ganesha, version >=2.1, if using NFS-Ganesha as the NFS server for the GlusterFS back end.

  • Install glusterfs and glusterfs-fuse package, version >=3.5.x, on the Shared File Systems service host.

  • Establish network connection between the Shared File Systems service host and the storage back end.

 Shared File Systems service driver configuration setting

The following parameters in the Shared File Systems service's configuration file need to be set:

  • share_driver = manila.share.drivers.glusterfs.GlusterfsShareDriver

  • If the back-end GlusterFS server runs on the Shared File Systems service host machine,

    • glusterfs_target = <glustervolserver>:/<glustervolid>

    And if the back-end GlusterFS server runs remotely,

    • glusterfs_target = <username>@<glustervolserver>:/<glustervolid>

The following configuration parameters are optional:

  • glusterfs_nfs_server_type =

    <NFS server type used by the GlusterFS back end, Gluster or Ganesha. Gluster is the default type>

  • glusterfs_mount_point_base =

    <base path of GlusterFS volume mounted on the Shared File Systems service host>

  • glusterfs_path_to_private_key = <path to Shared File Systems service host's private key file>

  • glusterfs_server_password = <password of remote GlusterFS server machine>

 Known restrictions

  • The driver does not support network segmented multi-tenancy model, but instead works over a flat network, where the tenants share a network.

  • If NFS Ganesha is the NFS server used by the GlusterFS back end, then the shares can be accessed by NFSv3 and v4 protocols. However, if Gluster NFS is used by the GlusterFS back end, then the shares can only be accessed by NFSv3 protocol.

  • All Shared File Systems service shares, which map to subdirectories within a GlusterFS volume, are currently created within a single GlusterFS volume of a GlusterFS storage pool.

  • The driver does not provide read-only access level for shares.

 Driver configuration options

Configuration options specific to this driver are documented here: Table 3.13, “Description of GlusterFS Share Drivers configuration options”.
