<br><font size=2 face="Arial">Hi All,</font>
<br>
<br><font size=2 face="Arial">We are running Scyld 28cz-7 on our cluster.</font>
<br>
<br><font size=2 face="Arial">One of our nodes (Compute Node 0) in the cluster was replaced because of bad motherboard. So the MAC address has changed. The hard disk wasn't changed but some linux was installed into it for testing purposes. I'm trying to add this node back to the cluster. Using beosetup, the new MAC address was registered as node 0.</font>
<br>
<br><font size=2 face="Arial">I tried to partition the disk using the beofdisk tool, then I restarted the node:</font>
