查看硬盘剩余空间 #df -h #df -H
查看目录占用空间 #du -hs 目录名

2. df du 命令
下面是相关命令的解释：
#df -hl 查看磁盘剩余空间
#df -h 查看每个根路径的分区大小
#du -sh [目录名] 返回该目录的大小
#du -sm [文件夹] 返回该文件夹总M数
3. 查看磁盘情况
#fdisk -l
[root@VM_28_226_centos ~]# fdisk -l

4.挂载磁盘
先格式化这个磁盘
#mkfs -t ext3 /dev/vdb
把磁盘挂载到/data 目录
#mount /dev/vdb /data/
设置开机自动挂载
#vim /etc/fstab
添加一条
/dev/vdb /data ext3 defaults 0 0
