Changing My RAID Array,Removing A Device To Grow Array Size huh?

See my previous post, on how to remove a device and partitioning.

See my previous post, on how to check status of recovery and rebuilding.

Note that you can still use the array, use the computer, read and save files while the array is recovering. I have this third post because I still want to remove the 1TB block device legacy component of the array. The removal of this smaller size device will increase the array size to 4TB from 3TB. Yup, I removed 1TB but increased the array size by 1TB. The annoying part of using RAID with different size block device is a lot of space is wasted or unused. You can check your RAID configurations in the raid-calculator sites out in the internet.

So I'm trying to fix my RAID by using same size block devices. I don't want to waste storage space which could amount to half the total raw storage space. Using RAID makes you think about three things: amount of storage available for use, performance and data protection. You have to maximize the configuration on all three fronts.

In this post, I told you I bought two 3TB Seagate hard disks. I might want to partition these into 1TB-2TB partitions and then add them to the array. I am going to be up against my motherboard's capacity here. I only have 6 SATA connections. I have a fast SSD using one already. I only have five slots for my array devices. I previously removed my optical drive to maximize the SATA connections. I could buy a PCI expansion card if that is actually needed.

Mailvelope, Encryption for Webmail

Encryption is the topic of week. I wrote about it in a related post here. While encryption is a very good idea, doing it and doing it every day as part of your work flow is another thing. My view is that if you're already using an email client then it is easier, simpler and more convenient to adopt encryption. That is not the case if you're using a webmail service. If you are using the browser to check, compose and send your email, what are your options? The answer is: it's complicated. Looking for a way to do encryption with Google Chrome and Gmail, I found this. I also read that Google just released code for email encryption as open source. But it's a long way to being used by end users. The extension for Google Chrome works fine if the recipient also uses Google Chrome. But I went ahead and check this on Evolution.

Donald Trump Is The 45th President of the United States

and he is preparing to move with his transition team into the Oval Office. His election is a shock to many political observers and the world in general. Donald Trump, the president-elect, ran against Hillary Clinton, former Secretary of State and for many the most qualified candidate for the presidency in many years. This has led to many post election analysis of how this upset happened. The numbers of votes for each candidate and the comparisons with previous presidential elections point to the fact that the white vote for Mr. Trump is solid all throughout but the minority and black votes did not come for Mrs. Clinton. This is what happened in crucial States like Michigan and Florida. The Republicans kept Congress and the Senate. It is quite notable that Russia and in particular, Vladimir Putin, is happy that they are going to talk to Mr. Trump rather than Mrs. Clinton. It is also a ...

Webapps in Unity

So it has been 4 months since Ubuntu 14.04 came out. This is LTS and supported for 6 years by Canonical. The first mobile device with Ubuntu pre-installed is promised to come out later this year, 2014. It's time to check out how the apps perform so far. It is a good idea. I use Gmail and Twitter and Facebook. Why not a webapp in a desktop? So I start the Twitter and Gmail webapp. So far it has crashed my computer 6 times. Not a very good sign. On the other hand it does work but not as stable as opening them in Firefox. -- Use my PGP key if you want to encrypt your replies/messages to me.
