Best Operating System for me.

IMG_0276

Over the years I’ve changed my operating system a lot. Sometimes too regularly. A lot if my day to day work is managing remote servers over SSH or RDP.

OSX

I’ve been using a Mac mini at work now for a little over a year. Its a great spec, (i7, 16GB RAM) and with multiple dual 24″ monitors it’s a system to be reckoned with. It’s got an underling *nix system so I have native access to linux tools, including SSH. With the addition of Homebrew a lot of tools are easily installable too.

Windows

I still lean towards Windows for gaming, mainly on Steam.

FPS is still loads better on my Windows 7 i5 machine.

Debian GNU Linux

I LOVE Debian. It’s always been my server os of choice. If multi monitor support was better and less work, no doubt it would be my main desktop OS. Gaming is getting so much better too.

OS Pros Cons
 OSX  Native *nix stuff. Great Multi monitor support.  Poor graphics support for gaming.
 Windows  Great multi monitor support  No native SSH/linux stuff.
 Debian  Flexibility, performance.  Poor multi monitor support.

It looks like I’m keeping a few different systems a while longer!

Expanding your LVM with a new disk

Our Debian LVM was getting a bit full so we got two new 2TB drives. We’ll add one of these to our LVM to increase the space.

First of all check to see if your new disk has been seen by the  BIOS.

If it has great! If not might be worth rebooting to check if a SATA port needs turning on for instance.

Once the disk has been recognised by the system it will show up with the above command.

We now know that the disk is /dev/sdb. Thats good. We can now prepare it for use.

Hit ‘n’ to create a new partition. It should be primary (p)
choose the default partition number (usually 1)
I hit enter twice to use the full space.

Press ‘p’ and you should see something similar to this:

Press ‘t’ to change the partitions id. Use 8e as it’s going to be a Linux LVM.

Hit ‘w’ to write the changes.

Now lets create a volume:

Now we need to find the name of our existing volume group to add this volume too:

 

Great! Lets extend the id05 LVM to use /dev/sdb1 as well:

pvscan should now show us the physical volumes to confirm:

Now lets find the logical volume that we want to increase. The lvdisplay command will show them all:

Here we have 2 (the other one is a swap)  The one we want to make bigger is /dev/id05/root.

Now lets resize the filesystem (this may take some time!)

All done! Check your new lovely space out!

Will

image

This time last week I was driving down to Leicester to see Will in hospital. Then the news wasn’t good and there was a lot of worry. A week later we have seen some positive days and some good signs that the brain damage isn’t as bad as first expected. I know that Will us going to get through this. He has shown this week that he is a tough cookie. Seeing him smiling at good friends yesterday was the best thing ever. At this point the “twinometer” was going bonkers.

I can’t wait to see him today. Every day I see little things that are positive which proves to us all that he is getting better.

Sometimes its a shame that something like this has to happen to remind us of how important our family and loved ones are.

I’ve been totally bowled over by the support and love that has been shown to Will and us while we have been here so far.

I love you Will x
