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 is user.DosStream."ADS-NAME".

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.
