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 
 
 Check Disk Usage to see which disk is affected 
 
 df -h 
 
 Check volume group for free space 
 
 sudo vgdisplay 
 If there is no space, you will need to allocate more trough Hypervisor 
 
 Expanding filesystem roof 
 
 Extend logical volume 
 
 sudo lvextend -l +100%FREE /dev/ubuntu-vg/ubuntu-lv 
 This will add remaining space to the root system 
 
 Resize filesystem 
 
 sudo resize2fs /dev/ubuntu-vg/ubuntu-lv 
 
 Verify disk size and usage 
 
 df -h / 
 
 Fix GPT/ Partition Table 
 If you run into problem where even after expanding filesystem roof it still stays at original number we might need to fix gpt/ partition table. Usually after running command below we would get following message. 
 
 Check Disk size vs Partition Size 
 
 sudo fdisk -l /dev/sda 
 GPT PMBR size mismatch (67108863 != 134217727) will be corrected by write. The backup GPT table is not on the end of the device 
 
 Fix GPT/ Partition Table 
 
 sudo gdisk /dev/sda
# Press 'v' to verify, then 'w' to write fixes 
 
 Resize the partition 
 
 sudo parted /dev/sda
(parted) resizepart 3 100%
(parted) quit 
 
 Reload partition table 
 
 sudo partprobe /dev/sda 
 
 Resize physical volume 
 
 sudo pvresize /dev/sda3 
 
 Check VG Free Space 
 
 sudo vgdisplay 
 
 Expand Logical Volume 
 
 sudo lvextend -l +100%FREE /dev/ubuntu-vg/ubuntu-lv 
 
 Resize Filesystem 
 
 sudo resize2fs /dev/ubuntu-vg/ubuntu-lv 
 At the end verify to make sure its actually resized 
 df -h /
