&gt; &quot;Hello, <br>
&gt; <br>
&gt; not exactly a hobbit problem, but as I am using rrd only with hobbit:
<br>
&gt; <br>
&gt; I am converting my old hobbit/xymon server to a new one &nbsp;Copying
<br>
&gt; just the data/rrd directory <br>
&gt; results in the message &quot;ERROR: This RRD was created on another
architecture&quot;. <br>
&gt; So I used &quot;rrdtool dump &lt;file&gt;.rrd &gt; &lt;file&gt;.xml&quot;
on the old <br>
&gt; and &quot;rrdtool restore &nbsp;&lt;file&gt;.xml &lt;file&gt;.rrd
-f&quot; on the new server. <br>
&gt; Using the &quot;--no-header&quot; <br>
&gt; option to rrddump makes no difference. No error messages during the
<br>
&gt; restore and no <br>
&gt; errors when I call the web pages. <br>
&gt; <br>
&gt; The new disk values in the rrd graphs are only 1/10 of the original
<br>
&gt; size, e. g. a disk which is <br>
&gt; 82 % filled, shows up with only &nbsp;8 %.. The text lines generated
from<br>
&gt; the client data are correct. <br>
&gt; <br>
&gt; Relevant data from the old server: </font></tt>
<br><tt><font size=2>&gt; <br>

<br><tt><font size=2>&gt; <br>
&gt; Following a hint from a hobbit user, I also tried to use a rrdtool
<br>
&gt; in between the versions above:</font></tt>
<br><tt><font size=2>&gt; <br>
&gt; dump with 1.0.49 on 32 bit, restore with 1.2.23 on 32 bit, dump with<br>
&gt; the same 1.2.23</font></tt>
<br><tt><font size=2>&gt; on 32 bit, restore with 1.3.4 on 64 bit. No difference.
And it <br>
&gt; effects all graphs, not only </font></tt>
<br><tt><font size=2>&gt; the disk graphs.</font></tt>
