Expanding VM Filesystem Size

If the VM hits the size limit, but there is more space allocated, or you allocated the space. These steps will help with expanding the size of the volume.

 

Checking the Size

1. Check Disk Usage to see which disk is affected

df -h

2. Check volume group for free space

sudo vgdisplay

If there is no space, you will need to allocate more trough Hypervisor

 

Expanding filesystem roof

1. Extend logical volume

sudo lvextend -l +100%FREE /dev/ubuntu-vg/ubuntu-lv

This will add remaining space to the root system

2. Resize filesystem

sudo resize2fs /dev/ubuntu-vg/ubuntu-lv

3. Verify disk size and usage

df -h /
