I will try one more time. Can someone please tell me if it is possible to recover a mirrored drive? If not then why are so many people using mirrors out there?<br>

Btw. it's a good idea to state your lvm version.<div></div></blockquote></div><div>Sorry if I did not in my previous post. Most of the lvm tools say:</div><div><div> LVM version: 2.02.28 (2007-08-24)</div>

</blockquote></div>
To make the VG consistent again you use "vgreduce --removemissing VG".<br>
That will remove any LVs that were (even partially) on any missing PV.<br>
When mirror legs are lost this way then mirror get downconverted.<br>
You may want to use it with --test first, to see what you would loose.</blockquote><div><br></div></div><div>I had used --test and it looked like the only loss was that LV.</div><div class="Ih2E3d"><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
<br>
(And you may try --mirrorsonly, it should fail when anything except mirror<br>
legs would be lost. Without guarantee, depends on version.)</blockquote><div><br></div></div><div>Oh, so what you explained above that must be why the LV is gone now? So how do I go from the LV that is now gone to an LV with only that one partition? I cannot even see the volume group anymore since that seems to be now, "reduced"? :-)</div>

As a second question, I know the extents and such. Is there a way to copy off the data into a non-lvm partition? At this point I will even take that. I just want to get to the data.<br>
</blockquote></div>
Partial activation: "vgchange -ay -P". Doesn't make much sense<br>
if you only lost a mirror leg.<br>
<br>
<br>
Btw. when you need realtime response to your problem,<br>
there is an irc channel #lvm on freenode (ask question and wait).</blockquote><div> </div></div><div>No thank you, at the moment I don't need real time response. Any response is a help. I had posted twice before this from last Saturday and this is my only response. I was not even sure I was getting through to the group since I did not get any of the messages I posted previously.</div>

</blockquote></div>Okay. I guess that was possibly a little hard for a question. How about is there a way to only copy the extent onto another partition? That way I only copy the data?<div><br></div><div>Gary</div>
