Resizing Virtual Ubuntu Server

  • 772

I have a virtual instance of Ubuntu Server running. Increased the virtual disk from 37GB to 50GB, but now stuck on getting the additional space to the LVM.

I have tried lvextend and resize2fs with the following results;

sudo lvextend -L +14G /dev/ubuntu-vg/ubuntu-lv
Insufficient free space: 3584 extents needed, but only 0 available

sudo resize2fs -p /dev/ubuntu-vg/ubuntu-lv 
The filesystem is already 9042944 (4k) blocks long.  Nothing to do!

sudo lsblk
