[root@localhost ~]#

mkfs -t ext4 /dev/sda //格式化硬盘
mkdir data //创建挂载目录#mount 硬盘地址 要挂载的地址、需指定文件目录
#mount /dev/sdb /data //挂载#df -h //查看是否挂载
#umount /dev/sdb //卸载硬盘挂载

//因为mount挂载在重启服务器后会失效，所以需要将分区信息写到/etc/fstab文件中让它永久挂载：
[root@oracle /]# vim /etc/fstab加入：
/dev/sdb1(磁盘分区) /data1（挂载目录） ext3（文件格式）defaults 0 0
