Personally, I find LVM to be a great solution looking for a problem.  I
only have one LVM partition, and that's only because I forgot to turn it
off when I created it.  Of course, I'm only using Fedora for my home
computer, and I can see how useful it can be in a production
environment.  Maybe what we need is for anaconda to ask if this is a
home or production installation, and have LVM default to off for home,
on for production?

If it were simple then LVM would be wonderful.  If, on detecting a new
drive, the system would say "Hey, you have a new drive. Do you want me
to extend one or more existing partitions there?", it would be workable.
But it's not that easy.

and this is good so
why?

because many naive people would say "yes extend" without realize
what happens if you have a LVM over 6 physical drives without a
RAID after one of the drives is dying

Having anything over multiple drives without RAID means you really know what you are doing, or really *don't* know what you are doing. At least with LVM you can get rid of the failing part if it doesn't die before you do.

I agree the LVM is really hard to use, because the UI was designed by someone who doesn't think the way I do. My impression is that a lot of other people share this opinion.
