FastDFS FAQ （欢迎反馈，我将及时整理）

注册个名字好难啊

余兄，我在做group集群时，不知道自己配置有误还是什么问题，有两个group，1和2.比如将文件上传到group1上面，通过浏览器group1/文件名可以访问到。但是改成group2/文件名  也可以访问到。我检查了一下group2下面的storage并没有该存储文件，是不是在group2下面没找到的时候，就根据文件名解析到源storageIP去进行查找。请教了

storage的日志如下：

现在192.168.1.92:80网页打不开  应该怎么修改错误呢

您好，group1 中 2台storage 配置fastdht后， 运行正常，

我在group1 中再次添加2台storage， storage中data目录大小与原2台storage相同， 但是 fdht目录中的__db.001 __db.002 __db.003  data目录大小都不同，

本机是192.168.30.73， 不能从其他3台机器上 同步fdht目录数据，请帮忙解答一下

天真花语

余大，想知道，现在fastdfs 现在有好的监控工具没

那位大神知道    java.io.IOException: recv cmd: 32 is not correct, expect cmd: 100 这个问题要怎么解决呢

您好，我想请教一个一直疑惑的问题，
同组内我有两台storage 机器 storage 1 和 storage 2 上面通过nginx 模块来负载这两台机器
假设文件上传到机器storage 1 我直接通过nginx 模块访问 机器storage 2 的时候会不会存在时间差导致404出现？

请问Java客户端上传文件的时候报这个错，怎么解决- java.io.IOException: recv package size -1 != 10

您好，请问 python api的问题
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib64/python2.6/site-packages/fdfs_client/client.py", line 83, in upload_by_filename
store_serv = tc.tracker_query_storage_stor_without_group()
File "/usr/lib64/python2.6/site-packages/fdfs_client/tracker_client.py", line 382, in tracker_query_storage_stor_without_group
raise DataError('[-] Error: %d, %s' % (th.status, os.strerror(th.status)))
fdfs_client.exceptions.DataError: [-] Error: 2, No such file or directory
您是怎么解决的呢？
我现在用这个api的时候也出现这样的错误，不过是在使用它上传从文件的时候，上传主文件的时候可以上传成功，错误如下：
Traceback (most recent call last):
  File "test.py", line 35, in upload_file
    slave_res=client.upload_slave_by_filename(slaveFilePath,master_fileId,"-html")
  File "/usr/local/lib/python2.7/site-packages/fdfs_client/client.py", line 162, in upload_slave_by_filename
    meta_dict = None)
  File "/usr/local/lib/python2.7/site-packages/fdfs_client/storage_client.py", line 289, in storage_upload_slave_by_filename
    file_ext_name)
  File "/usr/local/lib/python2.7/site-packages/fdfs_client/storage_client.py", line 217, in _storage_do_upload_file
    raise DataError('[-] Error: %d, %s' % (th.status, os.strerror(th.status)))
DataError: [-] Error: 2, No such file or directory

这是我在重装系统之后重新配置后运行时报的错，之前一直没问题，还请不吝赐教，谢谢。
