在单个tracker时uploadAppender、append没什么问题，有多个tracker时就会报错了。

fdfs.upload('e:/shou.jpg').then(function(fileId) {
// fileId 为 group + '/' + filename
console.log(fileId);
}).catch(function(err) {
console.error(err);
); //cache function error, no }

要用阿里云SLB对tracker做负载均衡和健康检查，但tracker allow_hosts不支持阿里云SLB健康检查地址网段 100.64.0.0/10
参考： 7. HTTP监听向后端ECS实例执行健康检查的IP地址是什么？
配置：

allow_hosts=10.2.14.0/23
allow_hosts=100.64.0.0/10 

[2019-05-22 21:52:25] ERROR - file: shared_func.c, line: 1620, ip address: 100.64.0.0/10, invalid network bits: 10, it should >= 16 and < 32

当我在调用upload append模式时首次添加数据后再调研append追加
反回的storage与首次上传的文件storage不是同一个，导致出现错误
如下
receive server packet headerBuffer: {"type":"Buffer","data":[0,0,0,0,0,0,0,0,100,2]}
{ Error: receive packet errno is: 2
at _parseHeader (server\node_modules\fdfs\lib\protocol.js:334:19)
at Socket.listener (node_modules\fdfs\lib\protocol.js:183:34)
at emitOne (events.js:96:13)
at Socket.emit (events.js:188:7)
at readableAddChunk (_stream_readable.js:176:18)
at Socket.Readable.push (_stream_readable.js:134:10)
at TCP.onread (net.js:551:20) errno: 2, code: 2 }
就目前观察是由于storage在每次追加时返回的不是源storage导致的，帮忙看看是不是？谢谢

招高级node.js，base上海。

fdfs can set store_path_index to save

环境
node v6.10.2
os: ubuntu 16

出错代码

let config= {
	fdfs: {
		upload: {
			host: 'xxx',
			port: 'xxx'
		},
		download: {
			host: 'xxx'
		},
		size: 1024000
	}
};

let getFdfs = (fdfs)=> {

  return new FdfsClient({
  // tracker servers
  trackers: [
    {
      // host: process.env.FDFS_UPLOAD,
      host: fdfs.upload.host,
      port: fdfs.upload.port
    }
  ],
  // 默认超时时间10s
  timeout: 1000000,

  // 默认后缀
  // 当获取不到文件后缀时使用
  defaultExt: 'png',
  // charset默认utf8
  charset: 'utf8'
  });
};

//busboy.......
busboy.on('file', function (fieldname, file, filename, encoding, mimetype) {

  let fdfs = getFdfs(config.fdfs);
  console.log('hei.......................................how are you')
  fdfs.upload(file, {size: config.fdfs.size}).then(function(fileId) {
    console.log('how ok ...........................')
    console.log(fileId);
  })
})

[输出]
一直卡在 start upload file to storage server 这一个步不动了

hei.......................................how are you
connect to tracker server [192.168.0.40:22122]

我就按照你的README一字不差写的，报错：
ReferenceError: FdfsClient is not defined

没有发现可以支持从文件的上传方法。有STORAGE_PROTO_CMD_UPLOAD_SLAVE_FILE这个命令声明却没有对应的方法？或者有没有相应的思路？

receive command: 32 is not equal to the expected command: 100
是客户端问题还是fastdfs部署的tracker或store server的问题
