Proxmox's guest-agent exec (PVE/QemuServer/Agent.pm) dies with "Wide character in subroutine entry" when input-data contains non-ASCII bytes. The growpart script had Cyrillic comments, so the whole auto-grow call returned 500 and the FS was never resized. Replace those comments with ASCII so the script reaches the guest.
