I'm running a VM with Centos 7 in a virtual environment (Proxmox). I'm out of space. So I've added some from Proxmox, booted from Gparted Live CD to allocate that space to /dev/sda2, but it won't let me resize. Please advice what can be done.
Gparted Live: Can't resize ext4 partition

You have a swap partition between /dev/sda2 and the free space. Turn off swap, remove the swap partition from /etc/fstab, then use Gparted to delete the swap partition /dev/sda3 and the extended partition /dev/sda4; you will then be able to extend /dev/sda2 in the adjacent free space.
