GlusterFS driver
GlusterFS driver uses GlusterFS, an open source distributed file system,
as the storage backend for serving file shares to Manila clients.
Supported shared filesystems
Supported Operations
- Create NFS Share
- Delete NFS Share
- Allow NFS Share access
- Deny NFS Share access
Requirements
- Install glusterfs-server package, version >= 3.5.x, on the storage backend.
- Install NFS-Ganesha, version >=2.1, if using NFS-Ganesha as the NFS server
for the GlusterFS backend.
- Install glusterfs and glusterfs-fuse package, version >=3.5.x, on the Manila
host.
- Establish network connection between the Manila host and the storage backend.
Manila driver configuration setting
The following parameters in the Manila’s configuration file need to be
set:
share_driver = manila.share.drivers.glusterfs.GlusterfsShareDriver
If the backend GlusterFS server runs on the Manila host machine,
- glusterfs_target = <glustervolserver>:/<glustervolid>
And if the backend GlusterFS server runs remotely,
- glusterfs_target = <username>@<glustervolserver>:/<glustervolid>
The following configuration parameters are optional:
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 backend, then the
shares can be accessed by NFSv3 and v4 protocols. However, if Gluster NFS is
used by the GlusterFS backend, then the shares can only be accessed by NFSv3
protocol.
- All Manila 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.
