How to create a Useable Partition from Ubuntu OS Installation Partition

cn flag

I have a problem with using the free space on my current disk, somehow the only space visible on the 512GB disk is 105GB.

Partition Break-down

  • Model: ATA SSD 512GB (scsi)

  • Disk /dev/sda: 512GB

  • Sector size (logical/physical): 512B/512B

  • Partition Table: gpt

  • Disk Flags:

  • Number Start End Size File system Name Flags

  • 1 1049kB 1128MB 1127MB fat32 boot, esp

  • 2 1128MB 3276MB 2147MB ext4

  • 3 3276MB 512GB 509GB

  • Model: Linux device-mapper (linear) (dm)

  • Disk /dev/mapper/ubuntu--vg-ubuntu--lv: 107GB

  • Sector size (logical/physical): 512B/512B

  • Partition Table: loop

  • Disk Flags:

  • Number Start End Size File system Flags

  • 1 0.00B 107GB 107GB ext4

Considering that I have 512GB SSD and 105GB is an LVM partition used for the OS installation, enter image description here

But the main disk is in SDA3 512GB along with the Freespace, but the free space is not visible on the useable partition in the previous image above. (see attached here enter image description here

Question is: My challenge is, instead of seeing the entire 473GB on my PC which is where the OS is installed, I can only see 105GB, any ideas.?

Thanks in anticipation.

I do not use LVM, but I understand it is difficult to shrink and very easy to expand. Default install does not use all the available space so you can either add volumes for /home or data or expand your / volume. http://askubuntu.com/questions/852019/i-wish-to-expand-my-lvm2-partition & http://askubuntu.com/questions/196125/how-can-i-resize-an-lvm-partition-i-e-physical-volume

Have a look at this tutorial. https://www.tecmint.com/extend-and-reduce-lvms-in-linux/

Follow the process from the heading “Extending Volume Group”. You can probably skip to the vgdisplay command. You should have a large amount of free PE. Follow the tutorial from there.

Good luck

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
