error code is :

seastar::future<> OSD::mkfs(
  FuturizedStore &store,
  unsigned whoami,
  uuid_d osd_uuid,
  uuid_d cluster_fsid,
  std::string osdspec_affinity)
{
  return store.start().then([&store, osd_uuid] {
    return store.mkfs(osd_uuid).handle_error(
      crimson::stateful_ec::handle([] (const auto& ec) {
        logger().error("error creating empty object store in {}: ({}) {}",
                       local_conf().get_val<std::string>("osd_data"),
                       ec.value(), ec.message());
        std::exit(EXIT_FAILURE);
      })); 
  }).then([&store] { ...

when mkfs handle error, std::exit will not stop sharded object but destory the sharded object directly, so the assertion happens.
