现在运行 1.28.0 版本的是我的备用节点，我的主节点目前正在运行回放测试。完成后，我会更新备用节点上的 NVMe 硬盘，然后它就成为我的主节点了。:) 谢谢你的提及。我没有遇到什么大问题。因为我是新见证人，所以我想冒着错过几个区块的风险来测试一下软件。祝一切顺利！（我是用机器翻译阅读你的帖子的。）

It is my back up node running the 1.28.0 now, my primary node is running a replay at the moment. Once complete, I update the Nvme(s) in my back up node and it becomes my primary. :) Thank you for the mention. I did not have any big problems. As I am a new witness I thought I could take the risk of a few missed blocks to test the software. All the best! (I used machine translation to read your post.)
