Ubuntu Additional disk space

When installing with Wubi, the default is 20G space, obviously not enough to add space from windows

First, use the Win7 disk partitioning tool to draw a new partition (lossless data) (such as NTFS) from any disk with more free space, which is used as a new space for Ubuntu.

Computer--management--Disk Management--disk 0--Select which partition, right--compress volume--wait for a piece of free partition--right-click New Simple volume, follow the instructions to go down

And then:

Mount the new disk under Linux to the specified directory/home or root directory/under (be sure to do a backup).

For example, add disk space to the/home directory:

Df-lh

Locate the location where the new disk is mounted, such as/DEV/SDA10, and the device number varies.

3. Reboot into single user mode (recovery modes), log in as root.

4, the format of the new partition is EXT4, can also be ext3:

Mkfs.ext4/dev/sda10

5. Back Up/home directory

Mv/home/home.bak

6. If the/home directory is already mounted, uninstall first, then delete:

Umount/home

Rm/home

7. Re-create the/home directory:

Mkdir/home

8. Mount the partition you just formatted to the/home directory:

Mount/dev/sda10/home

9. Restore all Files under/home:

Cp-r/home.bak/*/Home

10, set back the original user directory permissions:

Chown-r name:name File

Name is the user name, file is the user path, such as/home/zhengwei

11, modify the permissions:

CD ~/

Chown name. DMRC

Cd/home

Chown name Name

chmod 755 Name

12, edit the Fstab, so that the newly-entered devices automatically mount:

Vim/etc/fstab

Edit file,/dev/hda10/home Auto RW 0 0

Auto-recognize the disk format instead of auto. RW is readable and writable.

Last reboot, enter the system to view the remaining space of/home and/

Problems encountered:

In recover mode, unable to get root read-write permission, CP and MV operations are not valid

Execution at the command line: Mount-o REMOUNT,RW/

Can.

How to clean:

From the Internet to summarize the following several commonly used garbage cleanup methods:

1) Very useful to clean up the junk command:

#sudo Apt-get AutoClean

#sudo Apt-get Clean

#sudo Apt-get Autoremove

These three commands mainly clean up the upgrade cache and garbage packets.

2) Delete the old kernel and related configuration, you can go to the/boot directory, delete the old core/lib/modules the relevant module files

It's too dangerous!! If the kernel is deleted, there is no way to start it.

But there are ways to recover:
