[ale] Seeking LVM presentation [ was: LVM - Can't add new drive?]

[Nathan J. Underwood]

I'm using it, but don't know that I'm comfortable enough with it [yet] 
to show it off.  I also don't know that I could make it to a central 
meeting (I've only been able to make it to 1 west meeting).  I would 
definitely like to see this presented by one of the resident guru's 
though (this trial by fire stuff is fun, but it's killing me).
