  24       <div class="date">12th March 2014</div>
  25       <div class="body"><p>On larger sites, it is useful to use a dedicated storage server for
  26 storing user home directories and data.  The design for handling this
  27 in <a href="http://www.skolelinux.org/">Debian Edu / Skolelinux</a>, is
  28 to update the automount rules in LDAP and let the automount daemon on
  29 the clients take care of the rest.  I was reminded about the need to
  30 document this better when one of the customers of
  31 <a href="http://www.slxdrift.no/">Skolelinux Drift AS</a>, where I am
  32 on the board of directors, asked about how to do this.  The steps to
  33 get this working are the following:</p>
  34
  35 <p><ol>
  36
  37 <li>Add new storage server in DNS.  I use nas-server.intern as the
  38 example host here.</li>
  39
  40 <li>Add automoun LDAP information about this server in LDAP, to allow
  41 all clients to automatically mount it on reqeust.</li>
  42
  43 <li>Add the relevant entries in tjener.intern:/etc/fstab, because
  44 tjener.intern do not use automount to avoid mounting loops.</li>
  45
  46 </ol></p>
  47
  48 <p>DNS entries are added in GOsa², and not described here.  Follow the
  49 <a href="https://wiki.debian.org/DebianEdu/Documentation/Wheezy/GettingStarted">instructions
  50 in the manual</a> (Machine Management with GOsa² in section Getting
  51 started).</p>
  52
  53 <p>Ensure that the NFS export points on the server are exported to the
  54 relevant subnets or machines:</p>
  55
  56 <p><blockquote><pre>
  57 root@tjener:~# showmount -e nas-server
  58 Export list for nas-server:
  59 /storage         10.0.0.0/8
  60 root@tjener:~#
  61 </pre></blockquote></p>
  62
  63 <p>Here everything on the backbone network is granted access to the
  64 /storage export.  With NFSv3 it is slightly better to limit it to
  65 netgroup membership or single IP addresses to have some limits on the
  66 NFS access.</p>
  67
  68 <p>The next step is to update LDAP.  This can not be done using GOsa²,
  69 because it lack a module for automount.  Instead, use ldapvi and add
  70 the required LDAP objects using an editor.</p>
  71
  72 <p><blockquote><pre>
  73 ldapvi --ldap-conf -ZD '(cn=admin)' -b ou=automount,dc=skole,dc=skolelinux,dc=no
  74 </pre></blockquote></p>
  75
  76 <p>When the editor show up, add the following LDAP objects at the
  77 bottom of the document.  The "/&" part in the last LDAP object is a
  78 wild card matching everything the nas-server exports, removing the
  79 need to list individual mount points in LDAP.</p>
  80
  81 <p><blockquote><pre>
  82 add cn=nas-server,ou=auto.skole,ou=automount,dc=skole,dc=skolelinux,dc=no
  83 objectClass: automount
  84 cn: nas-server
  85 automountInformation: -fstype=autofs --timeout=60 ldap:ou=auto.nas-server,ou=automount,dc=skole,dc=skolelinux,dc=no
  86
  87 add ou=auto.nas-server,ou=automount,dc=skole,dc=skolelinux,dc=no
  88 objectClass: top
  89 objectClass: automountMap
  90 ou: auto.nas-server
  91
  92 add cn=/,ou=auto.nas-server,ou=automount,dc=skole,dc=skolelinux,dc=no
  93 objectClass: automount
  94 cn: /
  95 automountInformation: -fstype=nfs,tcp,rsize=32768,wsize=32768,rw,intr,hard,nodev,nosuid,noatime nas-server.intern:/&
  96 </pre></blockquote></p>
  97
  98 <p>The last step to remember is to mount the relevant mount points in
  99 tjener.intern by adding them to /etc/fstab, creating the mount
 100 directories using mkdir and running "mount -a" to mount them.</p>
 101
 102 <p>When this is done, your users should be able to access the files on
 103 the storage server directly by just visiting the
 104 /tjener/nas-server/storage/ directory using any application on any
 105 workstation, LTSP client or LTSP server.</p>
