如何在虚拟机ubuntu上增加硬盘空间

一前言:我们刚开始在虚拟机上安装ubuntu的时候,总是舍不得分配太多的硬盘空间。但用着用着时间久了硬盘就不够了。一种最笨的方法就是重装系统,但却费时费神。如果能够在不重装系统的情况下增加硬盘就好了。下面就来实现它。

.

1.首先把ubuntu shutdown.

2.VMware里点击菜单VM——>Settings

3.Hardware里面单击底下的Add按钮,然后选择Hard Disk——>Next——>Next——>Disk size(GB)是新增硬盘的大小——>Next——>Finish——>Ok. 这样在VMwareDevices里就多了一个Hard Disk 2。【可以直接增加虚拟机硬盘的方式实现;进入编辑虚拟机设置--》Hard Disk ->Expand-> 设置新的虚拟机硬盘大小】

三,接下来就是进入ubuntu,把新的硬盘mount进去了。

1.

root@sparkle-desktop:~# fdisk -l

 

Disk /dev/sda: 17.1 GB, 17179869184 bytes

255 heads, 63 sectors/track, 2088 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

Disk identifier: 0x000af2a2

 

   Device Boot      Start         End      Blocks   Id  System

/dev/sda1   *           1         993     7976241   83  Linux

/dev/sda2             994        1044      409657+   5  Extended

/dev/sda5             994        1044      409626   82  Linux swap / Solaris

 

Disk /dev/sdb: 8589 MB, 8589934592 bytes

255 heads, 63 sectors/track, 1044 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

Disk identifier: 0x00000000

 

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

 

可以看到多了一个 /dev/sdb

2.

下面是格式化成ext3文件系统

root@sparkle-desktop:~# mkfs -t ext3 /dev/sdb

mke2fs 1.40.8 (13-Mar-2008)

/dev/sdb is entire device, not just one partition!

Proceed anyway? (y,n) y  //把整个新硬件格式化,不分区。

Filesystem label=

OS type: Linux

Block size=4096 (log=2)

Fragment size=4096 (log=2)

524288 inodes, 2097152 blocks

104857 blocks (5.00%) reserved for the super user

First data block=0

Maximum filesystem blocks=2147483648

64 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

 

Writing inode tables: done                            

Creating journal (32768 blocks): done

Writing superblocks and filesystem accounting information: done

 

This filesystem will be automatically checked every 26 mounts or

180 days, whichever comes first.  Use tune2fs -c or -i to override.

root@sparkle-desktop:~#

 

3.

root@sparkle-desktop:~# cd /home

root@sparkle-desktop:/home# mkdir work

root@sparkle-desktop:/home# mount /dev/sdb work  //把硬盘mountwork目录。

root@sparkle-desktop:/home# cd work

root@sparkle-desktop:/home/work# ls

lost+found

4.

df命令查看一下挂载情况

root@sparkle-desktop:~# df

Filesystem           1K-blocks      Used Available Use% Mounted on

/dev/sda1              7913216   7803524         0 100% /

varrun                  257788       240    257548   1% /var/run

varlock                 257788         0    257788   0% /var/lock

udev                    257788        48    257740   1% /dev

devshm                  257788        44    257744   1% /dev/shm

lrm                     257788     39760    218028  16% /lib/modules/2.6.24-19-generic/volatile

/dev/sdb               8322488    149632   7753428   2% /home/work

gvfs-fuse-daemon       7913216   7803524         0 100% /root/.gvfs

看到/dev/sdb               8322488    149632   7753428   2% /home/work

一项,   可见成功了。

5.实现启动自动挂载。

root@sparkle-desktop:~# gedit /etc/fstab

根据下面的格式

#               

我们自己添加:

/dev/sdb  /home/work    ext3 defaults 0 0

重启,这样就完成了增加硬盘的全部步骤了。
