Solving the The disk drive for /tmp is not ready yet or not present Error on Debian Web Servers


Dealing with server errors can be quite a daunting task, especially for those new to system administration. In this article, we will dive deep into one of the common errors faced by Debian web server users: “The disk drive for /tmp is not ready yet or not present”. We will not only explain the possible reasons behind this error but also provide a comprehensive guide on how to fix it. Additionally, we will use Secure Shell (SSH) in our solutions since it’s a crucial tool for any administrator.

Understanding the Error

This error typically arises during the boot process of the Debian machine. The “/tmp” directory is a temporary storage area for files produced or accessed by various system services and user applications. If the disk drive for this directory is not ready or not present, the resulting instability may cause certain applications to malfunction or even lead to system failure.

How to Solve the Error

We will now dive into how to solve this issue. Since we are accessing the server remotely, we will use SSH to login to the Debian machine and perform some system-level activities.

Step 1: SSH into the Server

Open up a terminal shell in your local machine and use the following command to SSH into the server. Note that you’ll need to replace “username” and “server_ip” with your actual username and server IP address.

    ssh username@server_ip

Step 2: Check fstab File

The “/etc/fstab” file is a system configuration file on Debian systems, responsible for defining how disk partitions and other block devices should be mounted into the filesystem. If the “/tmp” entry in this file is incorrect, it could be the reason why you are encountering this error.
In order to check this file, use command:

    sudo nano /etc/fstab

Look for the line with “/tmp” in it. If you see errors in the entry or if the entry doesn’t exist, you’ll need to correct it or create a new one respectively.

Step 3: Correcting or Adding /tmp Entry

If there’s no entry for “/tmp”, add the following line at the end of the file:

    tmpfs /tmp tmpfs defaults,noatime,nosuid,nodev,noexec,mode=1777,size=512M 0 0

If the entry exists, correct it to match the line above. Once done, press CTRL+X to close the editor, and Y when prompted to save your changes.

Step 4: Mounting /tmp Directory

After ensuring your fstab file is correct, the next step is to mount the “/tmp” directory using the following command:

    sudo mount /tmp

To confirm that “/tmp” is now properly mounted, use command:

    df -h

You should be able to see “/tmp” and its respective size in the output.

Step 5: Reboot the System

After fixing the fstab file and manually mounting “/tmp”, it’s always a good idea to reboot the system just to confirm that everything will still work on the next boot. To do this, use the command:

    sudo reboot

When your server comes back up, the disk drive for “/tmp” should now be ready and present.


That’s all about how to resolve the “The disk drive for /tmp is not ready yet or not present” error on Debian web servers. Remember, a little patience and troubleshooting can go a long way in system administration. Stay tuned for more problem solving tips and tricks in future posts!
