[MooseFS-Users] About the MFS du - sh do not match the size of the actual directory;

[F. <748...@qq...>]

Hello, we use the MFS to store small files that are static, but found a problem, we are a directory of the file size may not be enough 100 k, but in the upper du - sh found the directory size is 1.1 m, could you tell me the size of the directory in the MFS is determined by what or cause, will store the information, how directory the assembly. We applied many of these directories, excuse me, how can we solve or what solution is better.
There is a problem, can you tell me our chunkserver is based on the Lvm, want to ask next chunker how to obtain the size of the size
The results of our experiment is as follows:



[root@ftp-1-1 testdir]# stat ../testdir
  File: "../testdir"
  Size: 0               Blocks: 0          IO Block: 65536  目录

[root@ftp-1-1 testdir]# echo "a" >test			#我只echo一个字节
[root@ftp-1-1 testdir]# stat ../testdir
  File: "../testdir"							#目录的大小，却增加了200
  Size: 200             Blocks: 1          IO Block: 65536  目录

[root@ftp-1-1 testdir]# echo "ab" >test 			#如果echo 两个字节
[root@ftp-1-1 testdir]# stat ../testdir
  File: "../testdir"
  Size: 300             Blocks: 1          IO Block: 65536  目录大小就增加到了300个b	这个地方有待考究
