Understanding the error

Command:

or while saving the file with :wq

Error:

E514: write error (file system full?)

There are two possible reasons for the error that is:

  • No space left in the segment your file is located.
  • The file is located in a virtual filesystem.

Fix for E514: write error (file system full?)

The first check is to check if your file is located in a virtual or physical filesystem.

For example, if you are editing a file in /sys, it is not possible as the filesystem at /sys is a virtual filesystem and there is no usable memory available.

You can check the location at which the file is placed using the following command:

df -h location

Example:

df -h /sys

This will show that it is mounted on sysfs which is system filesystem and hence, cannot be used. If the filesystem is like "/dev/sda1", then it is a physical filesystem and you can edit the file.

If it is a virtual filesystem: There is no option.

If it is a physical filesystem: We need to free some space so that you can edit the file. Check which segments have free space using the following command:

df

It shows the percentage of memory that is in used. If a segment has 100% usage, you cannot edit the file.

  • Fix 1: Ask other users to free space

If the system is shared among multiple users, each user will have its own user account on the system. Use the following command:

cd /home
sudo du -sch *.

This will list the space used by different users on the system. Ask the users who are using maximum space to free memory.

  • Fix 2: Clear cache

Use the following command to clear cache in your system:

cd /home/<username>
sudo rm -rf .cache

This can clear several GBs depending on how frequently do you use the system.

  • Fix 3: Delete files you do not need

Use this command to find the space occupied by different directories in the current working directory:

sudo du -sch *.

Identify the directory or file consuming maximum space and delete them.

Following this, you will be able to free some space and finally, edit your file by fixing this error.
