Resized partition not expanding in DietPi on hyper-V

having an issue with my Dev environment where I am showing as out of space on both nodes:

  jaja@fauxPi108:~$ df -h

  udev             10M     0   10M   0% /dev

I have grown the underlying virtual disk but attempting to extend the OSs use of that space has proven difficult. using the dietpi-drivemanager

Review of log shows the following:

  Removed /etc/systemd/system/local-fs.target.wants/dietpi-fs_partition_resize.service.
  Disk /dev/sda: 8 GiB, 8589934592 bytes, 16777216 sectors

  Old situation:

  /dev/sda1  *     2048 16777215 16775168   8G 83 Linux

  The partition table has been altered.
  resize2fs 1.46.2 (28-Feb-2021)
  The filesystem is already 2096896 (4k) blocks long.  Nothing to do!

It appears the utility sees the original size of the disk and not the expanded disk shown in hyper-v

Can anyone help? I am SOL until I fix this and wondering if rebuilding it is not my best option.

can you share some information on your disk layout

lsblk -o name,fstype,label,size,ro,type,mountpoint,partuuid,uuid

Thanks for the comment and sure:

lsblk -o name,fstype,label,size,ro,type,mountpoint,partuuid,uuid

disk/partition available for the system has still a size of 8GB.

Yes, this is explicitly my issue. As you can see, the Virtual disk is actually more than double that size:

Sorry for the late reply, does the problem still exist?

I messed it up super bad and blew it away and rebuilt. Thanks for the concerns.
