How to increase the virtual machine Ubuntu HDD in VirtualBox

Setting up--〉 Storage

Click to select Controller--〉 Create a new virtual disk

Allocate size allocation size to your own needs

Then attribute that column to set "virtual hard disk (D)" as the first IDE controller from the channel; Click OK


A preface: We just started to install Ubuntu on the virtual machine, always reluctant to allocate too much hard disk space. But it's not enough to use the hard drive for a long time. One of the stupidest ways to do this is to reload the system, but it's time-consuming. It would be nice if you could add the hard drive without reloading the system. Here's how to implement it.

　　two.

1. First put Ubuntu shutdown.

2. Click on the menu in VMware vm-->settings

3. In hardware, click the Add button below and choose hard disk-->next-->next-->disk size (GB) is the size of the new drive-->next-->finish--> Ok. This will have a hard Disk 2 in VMware's devices.

　　third, the next step is to go into Ubuntu and mount the new hard drive in.

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

2.

Here is the format of the Ext3 file system

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//The whole new hardware is formatted, not partitioned.

3.

root@sparkle-desktop:~# Cd/home

root@sparkle-desktop:/home# mkdir Work

root@sparkle-desktop:/home# mount/dev/sdb Work//mount the hard drive to the work directory.

root@sparkle-desktop:/home# CD Work

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

Lost+found

4.

Check the Mount status with the DF command

root@sparkle-desktop:~# DF

Filesystem 1k-blocks used Available use% mounted on

/DEV/SDA1 7913216 7803524 0 100%/

Varrun 257788 257548 1%/var/run

Varlock 257788 0 257788 0%/var/lock

Udev 257788 257740 1%/dev

Devshm 257788 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

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

One, visible success.

5. Implement automatic mount on startup.

root@sparkle-desktop:~# sudo gnome-open/etc/fstab

According to the following format

# <file system> <mount point> <type> <options> <dump> <pass>

We add by ourselves:

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

Reboot so you can complete all the steps to add the hard drive.

6. The owner of the work folder loaded by the above steps is root, there are many permissions restrictions, I use sudo chmod 777 xxx (folder name) to modify permissions and sudo chown ubuntu (my username) work to modify the folder owner, Then you can copy and paste the file to the folder.
