</div>To me it sounds likely that the raid controller is shitty and<br>
is presenting two sets of devices to the OS, one likely being<br>
the "RAID" device and the other a more generic device(s).<br>
<br>
What does 'dmesg' say? Do you see more devices than you think<br>
you should have on the system?</blockquote><div>dmesg says nothing about this, the message only appears at console when booting or otherwise using the PVs:<br><br>[root@myserver ~]# pvs<br> Found duplicate PV 8D7K2wg15HqD0l9HxZCz7QlDfpqJOhXT: using /dev/sdb2 not /dev/sda2<br>

Don't think so, this machine was integrated here with new materials.<br>
<br>Oops... system-config-lvm shows under 'Uninitialized entities':<br>/dev/sda<br> -> part 1<br> -> part 2<br> -> unpartitioned space<br>/dev/sdb<br> -> part 1<br> -> unpartitioned space<br>
These shouldn't be appearing as two discs in the first place-- but anaconda said I only had one unit...<br>Anyway, why the asymmetry? Did I screw the RAID volume somehow? Or did I install plain on sda and this RAID never worked as such? :P<br>
The machine BIOS correctly describes the RAID volume at start. Doesn't It smell like fake RAID?<br>Should I declare sdb invalid to the firmware program so as to force resync?<br>Thanks again<br>-- <br>Eduardo Grosclaude<br>
