Hello, 

it works perfectly this way: 

lvextend -L ${newsize}G /dev/pve/vm-100-disk-1 

~# qm monitor 100 
Entering Qemu Monitor for VM 100 - type 'help' for help 
qm> block_resize drive-virtio0 30G 
qm> quit 

in VM: 
dmesg shows: 
[53925.713083] virtio_blk virtio0: new size: 62914560 512-byte logical 
blocks (32.2 GB/30.0 GiB)
