linux下挂盘

1、首先，查看磁盘，fdisk -l

Disk /dev/xvdf: 536.9 GB, 536870912000 bytes, 1048576000 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

2、进入磁盘，对磁盘进行分区

[root@shap000103262 ~]# fdisk /dev/xvdf
Welcome to fdisk (util-linux 2.23.2).

Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

Device does not contain a recognized partition table
Building a new DOS disklabel with disk identifier 0x9c0f9ab7.

Command (m for help): n
Partition type:
   p   primary (0 primary, 0 extended, 4 free)
   e   extended
Select (default p): p
Partition number (1-4, default 1): 1

Command (m for help): w

3、格式化分区

[root@shap000103262 ~]# mkfs.ext3 /dev/xvdf1

4、开始挂载分区

mount  /dev/xvdf1 /opt/share
