安装好之后，如果我们想对其元数据服务的性能进行评估和测试，可以安装MDTEST工具，具体的步骤如下：
安装和配置MPICH
MDTEST测试工具依赖MPI协议，所以需要首先安装MPICH（MPI协议的一种实现）。
# http://www.mpich.org/
$ yum install -y gcc gcc-c++ gcc-gfortran
$ wget http://www.mpich.org/static/downloads/3.3/mpich-3.3.tar.gz
$ tar xvf mpich-3.3.tar.gz
$ cd mpich-3.3/
$ ./configure --prefix=/usr/local/mpich
$ make -j $(nproc) && make install
$ cp -r examples/ /usr/local/mpich
$ vi ~/.bashrc
PATH=$PATH:/usr/local/mpich/bin
MANPATH=$MANPATH:/usr/local/mpich/man
export PATH MANPATH
$ . ~/.bashrc

-i: number of iterations the test will run
-I: number of items per directory in tree
-l: last number of tasks on which the test will run
-L: files only at leaf level of tree
-n: every process will creat/stat/read/remove # directories and files
-N: stride # between neighbor tasks for file/dir operation (local=0)
-p: pre-iteration delay (in seconds)
-r: only remove files or directories left behind by previous runs
-R: randomly stat files (optional argument for random seed)
-s: stride between the number of tasks for each test
-S: shared file access (file only, no directories)
-t: time unique working directory overhead
-T: only stat files/dirs
