I'm trying to extend my Virtual Machine's hard drive, on Ubuntu 16.04 server and have shut down the VM and increased the HDD size and I can see that /dev/sda is now 500GB in total from the previous 349GB.

What you did was extend the disk itself which is possible in a virtual environment, but not possible in real life as you cannot add more disk platters to an existing disk so the space is there, but it's not allocated to any partitions/volumes yet so boot the VM, ensure all services that need the Logical Volume you want to extend are stopped and do a:
fsadm --ext-offline --yes resize /dev/mapper/owncloud--vg-root 800G
to extend the Logical Volume itself: you're confusing LVMs and partitions: they are fundamentally different, have a look here on TLDP.

So from my understanding, 800G would have to be 500G in my scenario, and regarding the stopping of all services, there's quite alot of services running. So would this best be done from some kind of shell mode where nothing is running? Perhaps recovery mode?
