NAME

       vfs_glusterfs - Utilize features provided by GlusterFS

SYNOPSIS

       vfs objects = glusterfs

DESCRIPTION

       This VFS module is part of the samba(8) suite.

       GlusterFS (http://www.gluster.org) is an Open Source clustered file system capable of
       scaling to several peta-bytes. With its FUSE based native client, GlusterFS is available
       as a POSIX compliant file system and can hence be shared by Samba without additional
       steps.

       The vfs_glusterfs VFS module provides an alternative, and superior way to access a Gluster
       filesystem from Samba for sharing. It does not require a Gluster FUSE mount but directly
       accesses the GlusterFS daemon through its library libgfapi, thereby omitting the expensive
       kernel-userspace context switches and taking advantage of some of the more advanced
       features of GlusterFS.

       This module can be combined with other modules, but it should be the last module in the
       vfs objects list. Modules added to this list to the right of the glusterfs entry may not
       have any effect at all.

CONFIGURATION

       A basic configuration looks like this.

                     [share]
                     vfs objects = glusterfs
                     path = /relative/base/path
                     glusterfs:volume = gv0
                     kernel share modes = no

       Note that since vfs_glusterfs does not require a Gluster mount, the share path is treated
       differently than for other shares: It is interpreted as the base path of the share
       relative to the gluster volume used. Because this is usually not at the same time a system
       path, in a ctdb cluster setup where ctdb manages Samba, you need to set
       CTDB_SAMBA_SKIP_SHARE_CHECK=yes in ctdb's configuration file. Otherwise ctdb will not get
       healthy.

       Note that currently kernel share modes have to be disabled in a share running with the
       glusterfs vfs module for file serving to work properly.

OPTIONS

       glusterfs:logfile = path
           Defines whether and where to store a vfs_glusterfs specific logfile. Client variable
           substitution is supported (i.e. %M, %m, %I), hence per client log file can be
           specified.

           Example: glusterfs:logfile = /var/log/samba/glusterfs-vol2.%M.log

       glusterfs:loglevel = 0-9
           Defines the level of logging, with higher numbers corresponding to more verbosity. 0 -
           No logs; 9 - Trace log level; 7 being the info log level is preferred.

           If this option is not defined with an explicit loglevel, the glusterfs default is used
           (currently loglevel 7).

       glusterfs:volfile_server = servername
           Defines which volfile server to use, defaults to localhost.

       glusterfs:volume = volumename
           Defines the glusterfs volumename to use for this share.

VERSION

       This man page is correct for version 4.2.0 of the Samba suite.
