Upgrade: Ubuntu 14.04 To Ubuntu 16.04

Hi Reese

From :


It took me 6-8 hours to finish the upgrade. It's a very slow connection today, of all 
days.

Xenial is looking sharp and beautiful.

I did not encounter any problems with the upgrade. I'm downloading the image
through the torrents. I figure I should help out with the others who are downloading
a fresh ubuntu.

Part 2 - From Fedora 23 To Ubuntu 14.04 lts



Hi Reese

I followed some tutorials for creating RAID and filesystem then mounting
the RAID disks to an existing installation of linux. I checked the configuration
files for mdadm and fstab. I found nothing or so I thought.

I printed out results for fdisk and raid scan. It turns out I had copied the
wrong UUID for the RAID in my fstab file.

Didn't know that you can create a RAID level 5 with just two disks though.
Of course for practical purposes it's not RAID 5 but a RAID 1, two disks
mirroring each other because the parity are on two disks. I'm adding another
disk further on - maybe a spare disk later after that.

From Fedora 23 To Ubuntu 14.04 lts

Hi Reese

My project took me from using Fedora 23 to being unable to boot 
my PC to reinstalling the operating system to finally using 
Ubuntu 14.04 like a lifeboat. 

I was working on converting an old RAID 0 set up to a more 
robust RAID 5. RAID 5 will give me a chance to swap a replacement
hard drive for a failing one without, I had hoped, losing uptime
and data. After booting on a live cd to prepare the devices and
create the RAID, I tried to boot Fedora. No go. It kept shoving me
to "rescue mode". Uh-oh. I checked the RAID and it's clean and 
active. There's nothing wrong with the RAID or the conversion .
I checked the configuration files for mdadm and fstab. I don't
see anything odd. This is when I spent a lot of time googling. None
of the fixes I read worked.

Happy Easter and I Think It's My Birthday

 Hi Reese

The renovations of the bathroom and the kitchen continues through the
holy week. M Roger is making sure the wall plaster is smooth. He finished
putting the black marble tiles on the tabletop. He's going to put the doors
to the bathroom tomorrow. It's Easter, no work. Oh by the way, it's my 
birthday too, I think. 

I woke up with the Salubong passing the house. I could hear the band 
playing a march. The siren is wailing. When I got downstairs mom is washing
clothes and Imee is preparing pasta for the spaghetti. 

I've been tinkering with my phone's lock screen security. There was a point
when I couldn't open the screen anymore. I had to ask for help with a 'forgotten
password' issue. They asked for my google authentication credentials then google
sends me a code through sms. My sms app is locked too. I can't get to the code. 

The smartphone is a remarkable technology. What if a machine can handle millions 
of calculations per second and store pictures, documents and everything else that
can be reduced to zeros and ones, share information with other machines, and last 
but not the least, be portable enough so you can put it in your pocket. What's more
remarkable is I get to live long enough to see it for real.

Good Friday 2016

Time to think about the human condition,
Time to remember that we are saved by his death. We are made worthy of salvation only because..

How To - Swapping Hard Drives in A Raid

This is kind of a how to for changing a failed hard drive in a RAID 5 array.

Ian Campbell's Hotswapping a Failed RAID device

1) Mark the device as a failed RAID device.

2) Remove it from the array.

3) Tell the kernel to delete the device.

4) Physically swap the hard drives.

5) Add the new disk to the array.
