If one wanted redundancy only (is that RAID-0??) then I take it
you would skip LVM entirely, correct? - IOW, are the 2 mutually
exclusive or can you use LVM with RAID? The reason I ask is
because I'm starting to put together some plans to build a master
backend server (currently I have a frontend/backend combo) which will
not only house myth and it's recordings, but also all of my music and
pictures/videos of the kids. (the latter of which I would want
the redundancy in case of a drive failure). <br><br><div><span class="gmail_quote">On 10/14/05, <b class="gmail_sendername">Steve Adeff</b> <<a href="mailto:adeffs@gmail.com">adeffs@gmail.com</a>> wrote:</span><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
