Strange that it isn't creating the minor devices at boot. Is this a SATA drive or is it PATA/IDE and you ahve some strange jumper problem? Or bad cable? There's got to be a hint in the boot messages... Oh, I see that you said SCSI. Terminator missing?<br>
<br>Can you just reboot FC8, mount the new drive and copy files using the old system?<br><br>If you boot FC8, can you then run tune2fs or debugfs to see how things are configured?<br><br>Actually before modifying anything, if you have the space, I'd suggest doing dd copies to the new disk on a different partition just in case.<br>

<p class="MsoNormal">Good evening,</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">I have run into an odd problem and am hoping you can help.</p>
<p class="MsoNormal">- I upgraded my main server from FC8 to FC12 this evening.</p>
<p class="MsoNormal">- I replaced the boot HD so that I would have a snapshot
backup of the old system in case of problems.</p>
<p class="MsoNormal">- I installed the new OS on a fresh HD and tried to mount
the old partitions to get at the databases.</p>
<p class="MsoNormal">- Under F12 the old ext2 partitions don’t get created in
/dev.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal"># ls /dev/sd*</p>
<p class="MsoNormal">/dev/sda /dev/sda2 /dev/sda4
/dev/sdb /dev/sdb2 /dev/sdb4</p>
<p class="MsoNormal">/dev/sda1 /dev/sda3 /dev/sda5
/dev/sdb1 /dev/sdb3 /dev/sdc</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Notice there is a /dev/sdc, but no partition device
nodes. When I look the partitions are there and appear happy (see the
text at the end of this message). I can still boot off the old HD so it
is working properly.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal"><span style="font-size: 9pt;">When
I just create a new device node it doesn’t work properly:</span></p>

<p class="MsoNormal"><span style="font-size: 9pt;">#

<p class="MsoNormal"><span style="font-size: 9pt;"> </span></p>
<p class="MsoNormal"><span style="font-size: 9pt;">When
I try and take a closer look at a partition I get an odd error:</span></p>

<p class="MsoNormal"><span style="font-size: 9pt;">Googling

ideas of how to proceed?</span></p>
