I am running Ubuntu 18.04 server edition on an Intel NUC7CJYH, and noticed I only had about 50% of my SSD available. Running sudo lsblk showed the following:

NAME                      MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda                         8:0    0 465.8G  0 disk
├─sda1                      8:1    0   512M  0 part /boot/efi
├─sda2                      8:2    0     1G  0 part /boot
└─sda3                      8:3    0 464.3G  0 part
  └─ubuntu--vg-ubuntu--lv 253:0    0   200G  0 lvm  /

How can I resize the partition under sda3 to make use of the entire drive?

I found this question, but it is quite a bit more complex than what I am working with, and I'm not quite sure what to google to get to the root of my issue.

I appreciate any help!

It'd be interesing to see more logs but OOTB I wonder if you inadvertently setup a RAID[1] configuration.

A quick way to check is to run : sudo mdadm /dev/sda

or alternativelty check if these files exist and their contents:

  • cat /proc/mdstat
  • cat /etc/mdadm.conf

If this is indeed the case I suggest the fastest way in a new system is to simply reinstall making sure no RAID configuration is used. I believe it is possible to remove a RAID config on a live system but I'm not familiar enough with it and wouldn't risk it myself. A backup and reinstall might be the fastest path.
