I am new to Linux and new to Proxmox. I am running Proxmox as a VM under VMWare Workstation Pro (VMW). When creating this VM I allocated 500GB of host hard drive space to a single virtual drive. Later, from within VMW, I expanded this virtual drive from 500GB to 700GB.

Just after expanding the VMW virtual disk, I started the Proxmox VM. From within the VM, lsblk shows this:

The disk sda shows the new MVW virtual disk size of 700GB. How do I expand sda3 with the ultimate goal of pve-root seeing the added space?

I tried resizing what Proxmox thinks is the physical volume. I got a warning and I bravely proceeded (the advantage of running Proxmox as a snapshotted VM). But sda3 remained at 499GB.

root@test:~# pvresize /dev/sda3 --setphysicalvolumesize 700G
  WARNING: /dev/sda3: Overriding real size <499.00 GiB. You could lose data.
/dev/sda3: Requested size 700.00 GiB exceeds real size <499.00 GiB. Proceed?  [y/n]: y
  WARNING: /dev/sda3: Pretending size is 1468006400 not 1046476767 sectors.
  Physical volume "/dev/sda3" changed
  1 physical volume(s) resized or updated / 0 physical volume(s) not resized

Yet, nothing has changed:
