virtualbox 为 mint增加虚拟硬盘

来源：互联网发布：各种算法的时间复杂度编辑：程序博客网时间：2024/05/17 06:14

首先在virtualBox设置里，设置->介质->添加->选add harddisk，在弹出的对话框里选择新建，点击下一步，选择动态扩展（固定的分小了，又要在分，麻烦），点击下一步，选择大小，点击下一步，完成。【也可以】

接下来就要在Ubuntu里做相关设置。

    进入终端模式
    输入sudo fdisk /dev/sdb
    会提示
    The number of cylinders for this disk is set to 1365.
    Command (m for help):
    按m看help
    Command action
    a toggle a bootable flag
    b edit bsd disklabel
    c toggle the dos compatibility flag
    d delete a partition
     l list known partition types
    m print this menu
    n add a new partition
    o create a new empty DOS partition table
    p print the partition table
    q quit without saving changes
    s create a new empty Sun disklabel
    t change a partition’s system id
    u change display/entry units
    v verify the partition table
    w write table to disk and exit
    x extra functionality (experts only)
    按n创建分区，按p是查看分区
    Command (mfor help): n
    Commandaction
    eextended
    p primarypartition (1-4)
   e是创建扩展分区
   p是创建主分区
    按p
    p
    Partitionnumber (1-4):1
    Firstcylinder (1-1044, default 1):1
    Lastcylinder or +size or +sizeM or +sizeK (1-1044, default1044):1044
    Command (mfor help): w
   按w保存退出

   格式化开始，我选择的是ext3格式（文件系统类型可在 cd /sbin下查看）
   sudo mkfs -text3 /dev/sdb1
   然后我把这个硬盘挂在~/src下就可以了
    cd~/src   （cd  /usr/src）
   sudo mkdirsdb1
    sudo mount/dev/sdb1 ~/src/sdb1
    sudodf
   df命令是查看的意思
    文件系统 1K-块已用可用已用% 挂载点
   /dev/sda1             3842376  2822092   825096 78% /
    tmpfs                  190020        0   190020   0% /lib/init/rw
    varrun                 190020      120   189900   1% /var/run
    varlock                190020        0   190020   0% /var/lock
    udev                   190020      152   189868   1% /dev
    tmpfs                  190020       76   189944   1% /dev/shm
    lrm                      190020     2392   187628   2%/lib/modules/2.6.28-11-generic/volatile
    /dev/sda5         2885780   117632  2621560   5% /home
    /dev/sdb1        10792216   709508  9534492   7%/home/longzaitianguo/src/sdb1
    share              20482840 15891500  4591340 78% /mnt/share

（注：这里的share是我的Ubuntu和主机win7的共享文件夹）

   然后启动自动挂载
   sudo gedit/etc/fstab
   会看到如下文字
    #/etc/fstab: static file system information.
    #
    # Use'vol_id --uuid' to print the universally unique identifier fora
    # device;this may be used with UUID= as a more robust way to namedevices
    # that workseven if disks are added and removed. See fstab(5).
    #
    #
   proc           /proc          proc   defaults       0      0
    # / was on/dev/sda1 during installation
   UUID=b7806e98-1a61-48b2-b7c5-466626880479/              ext3   relatime,errors=remount-ro0      1
    # /home wason /dev/sda5 during installation
   UUID=94b20c91-2102-4544-8563-683a970b7677/home          ext3   relatime       0      2
    # swap wason /dev/sda6 during installation
   UUID=9a87d794-1296-4167-aa52-d7e496f8f5a3none           swap   sw             0      0
   /dev/scd0      /media/cdrom0   udf,iso9660user,noauto,exec,utf80      0
   /dev/fd0       /media/floppy0 auto   rw,user,noauto,exec,utf80      0
   依葫芦画瓢，添加
  /dev/sdb1 ~/src/sdb1 ext3defaults 00

<这里修改成UUID的模式更好，为了获取分区的UUID，可以通过ls -l/dev/disk/by-uuid获得每个硬盘分区的UUID>

这样就算完成了在虚拟机下添加虚拟硬盘的全部步骤。被添加在了: /usr/src/sdb1中
