在关闭数据节点前，需禁用副本分片的分配，避免不必要的 I/O 操作。通过以下命令将分片分配限制为仅主分片：

)
print(resp)

response = client.cluster.put_settings(body: {persistent: {'cluster.routing.allocation.enable' => 'primaries'}}
)
puts response

const response = await client.cluster.putSettings({persistent: {"cluster.routing.allocation.enable": "primarie
