Linux系统由于数据累计增长、前期存储规划不合理等诸多因素，出现存储不够用的情况时，这是可以添加硬盘，挂载上，让数据存储在新添加的硬盘上，具体做法如下：
1添加新硬盘到服务器，重启；
2.使用fdisk -l查看分区表信息

[root@DB-ONE-SERVER~]# fdisk -l
Disk /dev/sda: 42.9 GB, 42949672960 bytes
255 heads, 63 sectors/track, 5221 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes


   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1          13      104391   83  Linux
/dev/sda2              14        5221    41833260   8e  Linux LVM


Disk /dev/sdb: 21.4 GB, 21474836480 bytes
255 heads, 63 sectors/track, 2610 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes


Disk /dev/sdb doesn't contain a valid partition table


Disk /dev/dm-0: 32.3 GB, 32346472448 bytes
255 heads, 63 sectors/track, 3932 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
