1、新增磁盘分区总体示例

1.1 磁盘信息查看

[root@tangtang tmp]# fdisk -l

Disk /dev/vda: 107.4 GB, 107374182400 bytes, 209715200 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: 0x000ad887

   Device Boot      Start         End      Blocks   Id  System
/dev/vda1   *        2048     2099199     1048576   83  Linux
/dev/vda2         2099200    20971519     9436160   8e  Linux LVM

1.2 增加新分区 /dev/vda3 ，格式为 LVM

[root@tangtang tmp]# fdisk /dev/vda
