[ale] Topic ideas for November meeting

[Damon L Chesser]

I use LVM at every opportunity.  I also frequently use it in conjunction 
with an encrypted HD/partition (on my personal computers) thusly:

HD
|
    boot partition
    |
      LUKS encryption
         |
             LV with swap/root/home

Been doing that for years.  Never had a problem.

Never had a problem with just LVM at work.

The science on LVM is settled.  It is time for LVM deniers to  face reality.

OTOH, I have lately been questioning the usefulness of that extra layer 
of complexity.

I could do the exact same thing thus:

HD
|
     boot partition
     |
         LUKS encryption
             |
                 ext (or what have you) with a swap /file/.

You would lose EASY re-size ability (ie, shrink partition foo, grow 
partition bar, room problem solved, assuming bar was not used much and 
foo only needed the extra room bar had).  BUT (<- large but) I have 
NEVER had to do that with my personal machines.  I also never like to 
carve them up into seperate /, /home, /var, etc as that is of small 
value for a personal computer.  It has always been easier to make a / 
and put home in there.  It makes sizing guesses easier to deal with.  
yeah, LVM is cool, but on a personal level, I have never been able to 
take advantage of it, but I have had to take the time and resources 
(even though they are minimal, they are real) to run LVM.  Before this 
thread started, I started to ask "why?".

As for the back ups, back up /home on an external drive using rsync.  
Restore using rsync after I re-size with either a live cd or a 
re-install.  Normally done when I get tired of Fedora and re-install 
ubunut/debian/sabayon/whatever until I want to try Fedora again.

none of the above comes into play on work servers.  The science on LVM 
is settled then.  resizing with LVM has saved me many, many times from a 
backup/restore, even on vms (add a disk, LVM grow the problem file 
system).  Ugly, but expedient.  keep it limping until you can get rid of 
the "one off" mulit-disk vm with a proper size vm disk IAW work schedules.

HTH and my tongue in cheek is /not/ taken seriously.
