Description : NFS server running in User Space
NFS-GANESHA is a NFS server running in User Space. It is available under the
LGPL license.
It has been designed to meet two goals:
* providing very large metadata and data caches (up to millions of records)
* providing NFS exports to various files systems and namespaces (a set of
data organized as trees, with a structure similar to a files system)
NFS-GANESHA uses dedicated backend modules called FSAL (which stand for File
System Abstraction Layer) that provided the product with a unique API (used
internally) to access the underlying namespace. The FSAL module is basically
the "glue" between the namespace and the other part of NFS-GANESHA
Available FSALs are:
* FSAL/XFS : provides NFS frontend to XFS filesystems
* FSAL/ZFS : provides with a way to export ZFS's pool with NFS-GANESHA
* FSAL/LUSTRE : provides NFS frontend to LUSTRE filesystems (Lustre 2 or
higher is required for this FSAL)
* FSAL/PROXY: the module is in fact a NFSv4 client. Used with NFS-GANESHA,
it turns the NFS server into a NFS proxy server. This module is still in its
alpha version
* FSAL/FUSELIKE: many product use FUSE to have NFS export. Often they
resided in the user space. NFS-GANESHA is in user space too, and via this
module it allow user space product to have NFS export from user space, without
explicit kernel communication. The module use the same interface as the
classical fuse binding: if your application have a fuse binding module ready,
you'll need nothing else to interface it with NFS-GANESHA. For this specific
use, the NFS-GANESHA's engine is wrap in a library to be use and compile with
your proprieritary application.
* FSAL/SNMP: information available via SNMP are organized as trees, they
constitute a namespace. This backend module provides with the capability to
export SNMP information data via NFS and browse them in a "procfs-like" way.
* FSAL/POSIX: this module is based on the well known POSIX API which is
included in the LibC. It allows NFS export for anything accessible via the
POSIX interface. POSIX API addresses files and directories by their names
(which are volatile identifiers, they may change if object is renamed). FSAL
API uses persistent, opaque, unique identifier called handles. Because a this,
FSAL/POSIX use the service of a PostGresQL database to perform "reverse lookup"
from handle to filename.
