#### 1、查看硬盘信息 ####

*  fdisk -l
    
        Disk /dev/xvda: 21.5 GB, 21474836480 bytes
        255 heads, 63 sectors/track, 2610 cylinders, total 41943040 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 identifier: 0x000da36d
        Device Boot Start End Blocks Id System
        /dev/xvda1 * 2048 41940991 20969472 83 Linux
        Disk /dev/xvdb: 107.4 GB, 107374182400 bytes
        255 heads, 63 sectors/track, 13054 cylinders, total 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 identifier: 0x00000000
        Disk /dev/xvdb doesn't contain a valid partition table

#### 2、进入磁盘，对磁盘进行分区 ####

*  fdisk /dev/xvdb
    
        Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
        Building a new DOS disklabel with disk identifier 0xabf49954.
        Changes will remain in memory only, until you decide to write them.
        After that, of course, the previous content won't be recoverable.
        Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)
        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 First sector (2048-209715199, default 2048): Using default value 2048 Last sector, +sectors or +size{K,M,G} (2048-209715199, default 209715199): Using default value 209715199 Command (m for help): w The partition table has been altered! Calling ioctl() to re-read partition table. Syncing disks.
    
    “
 *  fdisk -l
    
        Disk /dev/xvda: 21.5 GB, 21474836480 bytes
        255 heads, 63 sectors/track, 2610 cylinders, total 41943040 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 identifier: 0x000da36d
        Device Boot Start End Blocks Id System
        /dev/xvda1 * 2048 41940991 20969472 83 Linux
        Disk /dev/xvdb: 107.4 GB, 107374182400 bytes
        43 heads, 44 sectors/track, 110843 cylinders, total 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 identifier: 0xabf49954
        Device Boot Start End Blocks Id System
        /dev/xvdb1 2048 209715199 104856576 83 Linux

#### 3、格式化分区 ####

*  mkfs.ext3 /dev/xvdb1 （将/dev/xvdb1格式化为ext3类型）
    
        mke2fs 1.42.9 (4-Feb-2014)
        Filesystem label=
        OS type: Linux
        Block size=4096 (log=2)
        Fragment size=4096 (log=2)
        Stride=0 blocks, Stripe width=0 blocks
        6553600 inodes, 26214144 blocks
        1310707 blocks (5.00%) reserved for the super user
        First data block=0
        Maximum filesystem blocks=4294967296
        800 block groups
        32768 blocks per group, 32768 fragments per group
        8192 inodes per group
        Superblock backups stored on blocks:
        32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208,
        4096000, 7962624, 11239424, 20480000, 23887872
        Allocating group tables: done
        Writing inode tables: done
        Creating journal (32768 blocks): done
        Writing superblocks and filesystem accounting information: done

#### 4、创建/disk2目录 ####

*  mkdir /disk2

#### 5、挂载 ####

*  mount /dev/xvdb1 /disk2/

#### 6、查看硬盘大小以及挂载分区 ####

*  df -h
    
        Filesystem Size Used Avail Use% Mounted on
        /dev/xvda1 20G 16G 3.4G 82% /
        none 4.0K 0 4.0K 0% /sys/fs/cgroup
        udev 3.9G 4.0K 3.9G 1% /dev
        tmpfs 799M 392K 799M 1% /run
        none 5.0M 0 5.0M 0% /run/lock
        none 3.9G 0 3.9G 0% /run/shm
        none 100M 0 100M 0% /run/user
        /dev/xvdb1 99G 60M 94G 1% /disk2

#### 7、配置开机自动挂载 ####

*  vim /etc/fstab
    
        /dev/xvdb1 /disk2 ext3 defaults 0 0
