Do you think I can copy the unknown partition from the second drive onto the first drive and have everything work again?<br><br><div class="gmail_quote">On Wed, Mar 3, 2010 at 4:01 PM, John R Pierce <span dir="ltr">&lt;<a href="mailto:pierce@hogranch.com">pierce@hogranch.com</a>&gt;</span> wrote:<br>

&gt; Hello Everyone,<br>
&gt;<br>
&gt; First time CentOS poster :)  I have CentOS 4 installed on the head<br>
&gt; node of a Sun Gridengine cluster set up in a RAID.  The head node has<br>
&gt; four hard drives, and I assume that drives 1 and 2 are in a raid and<br>
&gt; then drives 3 and 4 are in another raid.  I was trying to expand the<br>
&gt; OS partition on drive 1 because it was full.  I took drive 1 out, put<br>
&gt; it in my Fedora 8 box as a secondary drive, booted up into Fedora, and<br>
&gt; saw it had the partition structure:<br>
&gt; / 8GB<br>
&gt; /var 4GB<br>
&gt; /swap 1GB<br>
&gt; and an &quot;unknown&quot; partition 101.4GB<br>
</div>...<br>
<br>
<br>
probably LVM.<br>
<br>
wow, you made a nice mess.<br>
