Cant get VM disk size to fill available

[mudhauler]

I resized the disk of a VM via the GUI and followed the directions to get the VM to recognize it but I cant get it to work I think. Why is it showing Used 7.5G of 7.3G Avail?

~$ df -h
Filesystem      Size  Used Avail Use% Mounted on
tmpfs           393M 1008K  392M   1% /run
/dev/sda2        16G  7.7G  7.3G  52% /
tmpfs           2.0G     0  2.0G   0% /dev/shm
tmpfs           5.0M     0  5.0M   0% /run/lock
tmpfs           393M  4.0K  393M   1% /run/user/1000

When logging in the the VM it shows:
Usage of /: 48.7% of 15.64GB

What does "lsblk" show inside the VM?

Its likely that you have not finished all the steps required for space extension. You, probably, still need to expand the partition table and the file system.

lsblk shows:

wait, df shows your size is 16G. You used 7.7. You still have available 7.3
I think you are all set...

From what initial size to what size did you change the disk? As @bbgeek17 already made you verify, the VM sees a block device of 16G. Please post the VM config qm config <VMID> and the storage config cat /etc/pve/storage.cfg if that is not what you are expecting.
