LVM extension into new space and partition edits

[Bob Elzer]

You may also want to look at mondo rescue.  It can make a bare metal backup
and restore.

I haven't tried, but supposedly you can resize the partitions on restore.

Thanks for all the great discussion and advice!

I am planning ahead for this expansion of space.  We need it badly but not
so badly that we want to rush and risk data!  I was going to do it on
Saturday but that's Phoenix Bar Camp[1] so maybe the Saturday after that.
Or a long, late night this week.

The best advice I had not thought of was to test it.  Duh!  I'll be doing a
test first to make sure I'm good with the process.
