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.
A basic configuration looks like this.
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.
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. It could be list of white space separated elements where each
element could be
Note the restriction on naming a IPv6 host, it follows the same restriction that
is based on IPv6 naming in URL as per RFC 2732.
glusterfs:volume = volumename
Defines the glusterfs volumename to use for
This man page is correct for version 4.6.0 of the Samba suite.
The original Samba software and related utilities were created by Andrew
Tridgell. Samba is now developed by the Samba Team as an Open Source project
similar to the way the Linux kernel is developed.
