[SOLVED] Group的数据出现严重不平衡的问题

amusemelu

我现在集群有四个Group，每个Group有两个Storage Server
配置是默认配置, FastDFS版本是v3.06

Group的部分信息如下：
====================
Group1
--------
         total_upload_count = 0
         success_upload_count = 0
         total_file_open_count = 0
         success_file_open_count = 0
         total_file_write_count = 0
         success_file_write_count = 0

Group2
--------
         total_upload_count = 0
         success_upload_count = 0
         total_file_open_count = 0
         success_file_open_count = 0
         total_file_write_count = 0
         success_file_write_count = 0
Group3
-------
         total_upload_count = 418551
         success_upload_count = 418551
         total_file_open_count = 844753
         success_file_open_count = 844753
         total_file_write_count = 846089
         success_file_write_count = 846089

Group4
-------
            total_upload_count = 360240
        success_upload_count = 360240
          total_file_open_count = 726511
        success_file_open_count = 726511
        total_file_write_count = 728842
        success_file_write_count = 728842


问题：
1. 为什么Group之间会出现不平衡的问题？

2. 整个集群的文件数是多少？是success_upload_count的总和还是total_file_write_count的总和。为什么他们之间会相差一倍的？

如果没有删除过文件，为success_upload_count的总和。
total_file_write_count表示调用系统调用write的次数。

嗯，多谢老大。:wink:

数据的不平衡可能和这个参数有关。

# the method of selecting group to upload files
# 0: round robin
# 1: specify group
# 2: load balance, select the max free space group to upload file
store_lookup=2

因为Group3与Group4的空间比其它两个组大。

你自己找到原因就好，so good！
