You will hit an error with your e2fsck version. In my case the issue happened in Centos7, when I try to expand the disk for a fedora34 qcow2 image.

qemu-img resize fedora-new.qcow2 +20G

You will hit an error with your e2fsck version. You will need to download the latest source binary of e2fsprogs from your OS distributor and install it.

To install it from on CentOS 7. You will also need to install libguestfs-xfs on CentOS 7 to handle XFS file system with virt-builder utility. Otherwise you will hit below error. Get a newer version of e2fsck for virt-resize

sudo wget
sudo tar -xf e2fsprogs-1.45.6.tar.xz
sudo cd e2fsprogs-1.45.6
sudo ./configure
sudo make
sudo make install
sudo yum -y install libguestfs-xfs
