安装MFS

一、安装fuse

cd /home/dcplatform/lx/fuse-2.8.3

./configure --prefix=/home/dcplatform/fuse

make

sudo make install

 

添加到环境变量

echo "export PKG_CONFIG_PATH=/home/dcplatform/fuse/lib/pkgconfig/" >> ~/.bash_profile

source ~/.bash_profile

 

二、安装mfs

cd /home/dcplatform/lx/mfs-1.6.20-2

./configure --prefix=/home/dcplatform/mfs/ --sysconfdir=/home/dcplatform/mfs/etc --localstatedir=/home/dcplatform/mfs/var/lib --with-default-user=dcplatform --with-default-group=dcplatform

make

make install

 

添加到环境变量

echo "PATH=\$PATH:/home/dcplatform/mfs/sbin:/home/dcplatform/mfs/bin" >> ~/.bash_profile

source ~/.bash_profile 

 

三、master(10.131.18.4)

cp mfsmaster.cfg.dist mfsmaster.cfg

cp mfsexports.cfg.dist mfsexports.cfg

cp metadata.mfs.empty metadata.mfs

mfsmaster start

mfscgiserv start

 

四、master std(10.131.18.5)

sudo su - root

echo "10.125.70.17    mfsmaster" >> /etc/hosts

exit

 

cp mfsmetalogger.cfg.dist mfsmetalogger.cfg

mfsmetalogger start

 

五、chunck

sudo su - root

echo "10.125.70.17    mfsmaster" >> /etc/hosts

exit

 

cp /home/dcplatform/mfs/etc/mfschunkserver.cfg.dist /home/dcplatform/mfs/etc/mfschunkserver.cfg

cp /home/dcplatform/mfs/etc/mfshdd.cfg.dist /home/dcplatform/mfs/etc/mfshdd.cfg

 

sudo mkdir /opt/mfsdata/

sudo chown dcplatform:dcplatform /opt/mfsdata/ 

echo "/opt/mfsdata/" >> /home/dcplatform/mfs/etc/mfshdd.cfg

 

mfschunkserver start

 

六、mount

sudo su - root

echo "user_allow_other" >> /etc/fuse.conf

exit

 

sudo mkdir /opt/data_exchange_mfs/

sudo chown dcplatform:dcplatform /opt/data_exchange_mfs/

mfsmount /opt/data_exchange_mfs/ -H mfsmaster

 

 

7. 拷贝份数设置，只运行一次

mfsgetgoal /opt/data_exchange_mfs/

sudo mfssetgoal 3 /opt/data_exchange_mfs/

 

8.如果要取消mount

sudo umount /opt/data_exchange_mfs/
