VFS_STREAMS_XATTR(8) System Administration tools VFS_STREAMS_XATTR(8)NAMEvfs_streams_xattr - Store alternate data streams in posix xattrs
SYNOPSIS
vfs objects = streams_xattr
DESCRIPTION
This VFS module is part of the samba(7) suite.
The vfs_streams_xattr enables storing of NTFS alternate data streams in
the file system. As a normal posix file system does not support the
concept of multiple data streams per file, the streams_xattr module
stores the data in posix extended attributes (xattrs). The name of
these attributes by default is user.DosStream."ADS-NAME". The prefix
"user.DosStream." can be changed with the module option
streams_xattr:prefix, but be aware that this will also expose those ADS
over the SMB extended attributes interface.
The file system that is shared with this module enabled must support
xattrs.
Please note that most file systems have severe limitations on the size
of xattrs. So this module might work for applications like IE that
stores small zone information in streams but will fail for applications
that store serious amounts of data in ADSs.
CAUTION: Make sure to set "kernel oplocks = no" in smb.conf if if you
use this module because this combination is currently broken. See Bug
7537 for details.
OPTIONS
streams_xattr:prefix = STRING
Name prefix used when storing an ADS in an xattr, defaults to
user.DosStream.. Changing this will also expose ADS over the SMB
extended attributes interface.
streams_xattr:store_stream_type = [yes|no]
Whether the xattr names for Alternate Data Streams of type "$DATA"
are suffixed by the stream type string ":$DATA". The default is
yes.
