In this example i use the Ubuntu Linux on Hyper-V VM Gen2 and default LVM partitioning. Check your partitioning with lsblk. Now check the mount point with df -h. Resize disk on Hyper-V and  if you cannot view the total size you need reboot or rescan disk. # echo 1 > /sys/block/sda/device/rescan # parted GNU Parted 3.1 Using /dev/sda Welcome to GNU Parted! Type 'help' to view a list of commands. (parted) p Error: The backup GPT table is not at the end of the disk, as it should be.  This might mean that another operating system believes the disk is smaller.  Fix, by moving the backup to the end (and removing the old backup)? Fix/Ignore/Cancel? Fix Warning: Not all of the space available to /dev/sda appears to be used, you can fix the GPT to use all of the space (an extra 20971520 blocks) or continue with the current setting? Fix/Ignore?
