Adding A New Disk To A RAID Array part 2

I have added the new disk and the RAID array is finished syncing, now what?

You can check the result of the RAID sync with:

$sudo mdadm --detail /dev/md127
##Note the array size.

OR

In my case, I'm using logical volume management LVM.

$sudo pvdisplay
##Note the PV size

The PV size is what you can work with. In my case I want to allocate the free space to two logical volumes. I want to add 300GB to my Music lv and the rest to my Videos lv.

$sudo lvextend -L +300G /dev/ubuntu-vg/Music-lv
##This will add 300 GB to my Music-lv.

$sudo lvextend -l +100%FREE /dev/ubuntu-vg/Videos-lv
##This will add the rest of the free space left to my Videos-lv.

We still need to extend the filesystem to the added space. I have ext4 filesystem.

$sudo resize2fs /dev/ubuntu-vg/Music-lv
##This extends the filesystem to the added space.

$sudo resize2fs /dev/ubuntu-vg/Videos-lv
##This extends the filesystem to the added space.

Check the results.

$df -h
[donato@archdesktop ~]$ df -ht ext4
Filesystem                         Size  Used Avail Use% Mounted on
/dev/mapper/vol1-root               30G   18G   11G  62% /
/dev/mapper/vol1-home              174G   27G  138G  17% /home
/dev/mapper/ubuntu--vg-Music--lv   591G  210G  355G  38% /home/donato/Music
/dev/mapper/ubuntu--vg-Videos--lv  2.2T  1.1T  1.1T  51% /home/donato/Videos

Password Issues On Ubuntu Login

I found myself unable to enter my login credentials when prompted to do so in Ubuntu. I think I might have changed it then forget about it. I've been running the current session for more days than I should have. I forget. So what's the solution to my problem. How do I get in to my system now? It involved getting into the grub menu somehow. I am uncertain as to how to do that exactly in your system. So there's a couple of ways to do it (finger's crossed). When booting at system start, use the esc key or the shift key. The first one worked for me. The timing is key. Wait until the bios banner shows then hit the esc key once. I am using Ubuntu 22.04.4 here. I have a current version of grub. The grub menu will give you options and the one you want is: root. Yes you want root privileges to set the root password. It should give you a terminal access where you can issue commands. Type: #mount -rw -o -s remount / ==> this command mounts the filesyste...

Reflections On My Blogging: Keeping It Honest

When you're facing a white, blank screen trying to decide what to write, it seemed hopeless and hopeful at the same time. It's like watching a boat with its sails unfurled but there's no wind, yet you wait and then see the tide turning. You have to stop the distractions. Shut the door. Wait until your breathing is regular and your mind relaxed, like your wrists on the table infront of you. I imagine me looking sideways but not hearing anything. The sounds come much later. I see the big mass of color first, the greens. Just the vegetation, moving, not even individual trees, not leaves, just the big green. Then behind it the blue sky, unfocused and floating. Do not concern your brain with the details. Forget the words and the punctuations. But be mindful of the flow, trace the outlines, hear the motions. Sometime these things don't have a name, give it a name. How do you give something a name and still be honest? How do you keep your writing honest? I...

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.
