查询磁盘信息

{% codeblock lang:shell %}
[root@wing-centos ~]# fdisk -l

Disk /dev/vda: 42.9 GB, 42949672960 bytes, 83886080 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk label type: dos
Disk identifier: 0x000ee330

挂载硬盘

现在需要挂载/dev/vdb这个1TB的磁盘，先创建一个名为data的目录
{% codeblock lang:shell %}
[root@wing-centos /]# mkdir data
{% endcodeblock %}

然后将/dev/vdb挂载到data
{% codeblock lang:shell %}
[root@wing-centos /]# mount /dev/vdb data
{% endcodeblock %}

验证一下结果
{% codeblock lang:shell %}
[root@wing-centos data]# df -Th
Filesystem Type Size Used Avail Use% Mounted on
devtmpfs devtmpfs 7.9G 0 7.9G 0% /dev
tmpfs tmpfs 7.9G 0 7.9G 0% /dev/shm
tmpfs tmpfs 7.9G 8.6M 7.9G 1% /run
tmpfs tmpfs 7.9G 0 7.9G 0% /sys/fs/cgroup
/dev/vda2 xfs 36G 2.7G 34G 8% /
tmpfs tmpfs 1.6G 0 1.6G 0% /run/user/0
/dev/vdb ext4 985G 1.6G 933G 1% /data
{% endcodeblock %}

开机自动挂载

修改/etc/fstab文件
{% codeblock lang:shell %}
[root@wing-centos data]# vim /etc/fstab
{% endcodeblock %}

在文件最后一行添加记录

重启主机，验证结果
{% codeblock lang:shell %}
