Centos kernel Compilation: no space left on device Solution

1. Problem: Put the source code below the root directory

No space left on device appears during compilation.

Use the DF-H command to view the space occupied by the root directory.

2. Compile the source code in other places with sufficient space

In make module_install, no space left on device still appears.

However, the directory contains enough space.

, Continue DF-H

The root directory is full.

3. Solution

Delete unnecessary files in the root directory because the files must go through the root directory during installation,

Therefore, make sure that the root directory has sufficient space.
