Instructions</H1 +><P +>The Distributed File System (or Dfs) provides a means of + separating the logical view of files and directories that users + see from the actual physical locations of these resources on the + network. It allows for higher availability, smoother storage expansion, + load balancing etc. For more information about Dfs, refer to <A +HREF="http://www.microsoft.com/NTServer/nts/downloads/winfeatures/NTSDistrFile/AdminGuide.asp" +TARGET="_top" +> Microsoft documentation</A +>. </P +><P +>This document explains how to host a Dfs tree on a Unix + machine (for Dfs-aware clients to browse) using Samba.</P +><P +>To enable SMB-based DFS for Samba, configure it with the + <TT +CLASS="PARAMETER" +><I +>--with-msdfs</I +></TT +> option. Once built, a + Samba server can be made a Dfs server by setting the global + boolean <A +HREF="smb.conf.5.html#HOSTMSDFS" +TARGET="_top" +><TT +CLASS="PARAMETER" +><I +> host msdfs</I +></TT +></A +> parameter in the <TT +CLASS="FILENAME" +>smb.conf + </TT +> file. You designate a share as a Dfs root using the share + level boolean <A +HREF="smb.conf.5.html#MSDFSROOT" +TARGET="_top" +><TT +CLASS="PARAMETER" +><I +> msdfs root</I +></TT +></A +> parameter. A Dfs root directory on + Samba hosts Dfs links in the form of symbolic links that point + to other servers. For example, a symbolic link + <TT +CLASS="FILENAME" +>junction->msdfs:storage1\share1</TT +> in + the share directory acts as the Dfs junction. When Dfs-aware + clients attempt to access the junction link, they are redirected + to the storage location (in this case, \\storage1\share1).</P +><P +>Dfs trees on Samba work with all Dfs-aware clients ranging + from Windows 95 to 2000.</P +><P +>Here's an example of setting up a Dfs tree on a Samba + server.</P +><P +><PRE +CLASS="PROGRAMLISTING" +># The smb.conf file: +[global] + netbios name = SAMBA + host msdfs = yes + +[dfs] + path = /export/dfsroot + msdfs root = yes + </PRE +></P +><P +>In the /export/dfsroot directory we set up our dfs links to + other servers on the network.</P +><P +><TT +CLASS="PROMPT" +>root# </TT +><TT +CLASS="USERINPUT" +><B +>cd /export/dfsroot</B +></TT +></P +><P +><TT +CLASS="PROMPT" +>root# </TT +><TT +CLASS="USERINPUT" +><B +>chown root /export/dfsroot</B +></TT +></P +><P +><TT +CLASS="PROMPT" +>root# </TT +><TT +CLASS="USERINPUT" +><B +>chmod 755 /export/dfsroot</B +></TT +></P +><P +><TT +CLASS="PROMPT" +>root# </TT +><TT +CLASS="USERINPUT" +><B +>ln -s msdfs:storageA\\shareA linka</B +></TT +></P +><P +><TT +CLASS="PROMPT" +>root# </TT +><TT +CLASS="USERINPUT" +><B +>ln -s msdfs:serverB\\share,serverC\\share linkb</B +></TT +></P +><P +>You should set up the permissions and ownership of + the directory acting as the Dfs root such that only designated + users can create, delete or modify the msdfs links.
