fdisk -l 查看是否 已加入磁盘
fdisk /dev/sdb
fdisk -cu /dev/sdb 取消兼容模式
添加一个硬盘，只创建一个分区，然后把分区挂载到/data
第1个里程碑-进行分区
Command (m for help): n

e extended
p primary partition (1-4)
p
Partition number (1-4): 1
First sector (2048-208895, default 2048):
Using default value 2048
Last sector, +sectors or +size{K,M,G} (2048-208895, default 208895):
Using default value 208895
Command (m for help): p
Disk /dev/sdb: 106 MB, 106954752 bytes

第2个里程碑-通知系统/dev/sdb磁盘分区信息变化
partprobe /dev/sdb
第3个里程碑-格式化创建文件系统 make filesystem mkfs
[root@oldboyedu45-lnb ~]# mkfs.ext4 /dev/sdb1
mke2fs 1.41.12 (17-May-2010)
Filesystem label=
OS type: Linux
Block size=1024 (log=0)
Fragment size=1024 (log=0)
Writing superblocks and filesystem accounting information: done
This filesystem will be automatically checked every 31 mounts or
180 days, whichever comes first. Use tune2fs -c or -i to override.
4.关闭分区的自动磁盘检查功能
tune2fs -c 0 - i 0 /dev/sdb1
-c 没挂载多少次检查一次
-I 每隔多久检查一次磁盘
mount
/dev/sdb1 /data
df
-h
开机自动挂载
etc/rc.local
方法2
/etc/fstab
column -t 对其 /etc/fstab
