We still can logout an > ONBOOT session with "iscsiadm -m node -u comamnd". logout_by_startup does go by the startup setting, but I think you missed the session_in_use related code. It checks the mounts and holders already. Just change it for whatever you need. I think your lvm use case should be covered by the holder check. If not, add it.
