VirtualBox and Resizing an LVM root partition

New projects to work on!  That means configuring my virtual machines to fit more stuff.  I never seem to think ahead about how much space I need.  I work on a laptop with an SSD, so storage is a premium...

Sure, I could just create a new VM, but all those hours of customizing the environment, tweaking firewall and security settings, installing and building custom packages.  No way I want to do that again from scratch.

It shouldn't be too hard to extend my linux partition to make more room, right ? :eek a lot more involved than I thought.

Here is a collection of steps and sites I needed to make it all happen.

First resource:

This blog post is 90% of the process.

Warning: READ THROUGH BEFORE DOING.  It is really easy to screw everything up.

Here are some quick recaps:

  1. Backup your existing VDI (disk image).  Don't be a fool, just do it.
  2. Download the gparted liveCD ISO image here:  
  3. The easy part is the virtual box command to resize the virtual disk:
    • VBoxmanage modifyhd MyLinux.vdi --resize 100000
    • (this updates the VDI file to allow its size to be 100GB)
  4. Now you boot your linux VM with the gparted liveCD ISO you downloaded above and follow the instructions on Derek's blog post to update your primary LVM partition to use the available free space.  Not hard.
  5. Here is where it gets tricky, now open up this blog post: 
  6. Follow the directions starting with "Resizing the LVM stack":
    • Basically you will use the pvresize, lvextend and then resize2fs to get Linux to use that extra space you added.
    • You can read it on vBonHomme as good as here, so I'll give credit where credit is due.  Look up the exact commands their blog post.

Heckler:  Dude, why don't you just merge all this stuff into your blog so its all in one place! I am whining because I have to click on more than one link!

Response: Dude, I'm busy. Many tasks to complete.  This helped me, so I aggregate for you.  Maybe when I have time, I will <dramatic interruption ...> HAHA. Yeah right, I never have time to go back and re-write stuff. Yeah, you will just have to go to the links.

Hope this was helpful, and I hope my sarcastic style puts a smile on some people's faces.

Installing python 3.4.x on OSX El Capitan

I love "brew" package manager, but sometimes being too progressive breaks things.  I have several python apps that I maintain that get deployed to AWS using Elastic Beanstalk.  AWS eb can deploy with python 2.7 or 3.4.  Any recent 'brew install python3" will get 3.5.1. #annoying

Making Macbook Air with 128GB SSD usable with Bootcamp

I recently got a new Macbook Air 11" (the 2012 version) and loaded it with goodies like 8GB ram and 2GHz Core i7.  What I DIDN'T upgrade was the internal SSD.  My config came with 128GB SSD and I refused to pay $300+ to upgrade it to 256GB.  Yeah I know, some call me cheap, but SSds cost $75-$150 for 240GB, so adding another 128GB for $300 seemed way too steep for me.  I figured "ok, I'm going to make 128G work!"

Here is the story of how that went...

Election day plus 1: Social Media Nightmare

It is election day plus 1, and a very emotional day with no way to win for many.

Social media was a force to be reckoned with this election year.  No matter what position you take, the world is ready to pounce on you and tell you why YOU are evil, intolerant or a deplorable -- and the reason for all their woes.  This isn't a new problem, though...  All of the liberal vs conservative issues are causing rifts between otherwise civil people, and it seems to be the worst on Facebook and twitter.

If I say I am for Hillary:
i am part of the "corrupt system."

If I say I am against Hillary:
I am stupid and uneducated

If I say I am for Trump:
I am against women,
I am religiously intolerant,
I am a bigot

If I say I am against Trump:
I am against the 2nd amendment,
I don't have any idea how government works,
I am part of the problem with American society,
I am against the police

Stay with me now, this isn't meant to make people angry, but it is mean to shine some light on a social …
