Grub2 insists on including zfs module when it does not exist

Grub2 is a popular bootloader used in many Linux distributions to start the operating system during the boot process. It is responsible for loading the kernel and initializing the system. However, some users have reported an issue where Grub2 insists on including the zfs module even when it does not exist on their system.

This issue can be quite frustrating, especially for entry-level users who may not be familiar with the technical details of the system. In this article, we will explain why this problem occurs and provide a step-by-step guide on how to resolve it.

Understanding the Problem

First, let's understand what the zfs module is and why Grub2 includes it by default. ZFS (Zettabyte File System) is an advanced file system that provides features like data integrity, compression, and snapshot capabilities. It is commonly used in enterprise-level storage systems.

Grub2 includes the zfs module to support booting from ZFS partitions. However, most users do not have ZFS installed on their system, so including the zfs module becomes unnecessary and can cause issues during the boot process.

Resolving the Issue

To resolve the issue, we need to modify the Grub2 configuration file and remove the inclusion of the zfs module. Here are the steps you can follow:

1. Open a terminal window. You can usually find the terminal application in the "Utilities" or "Accessories" menu.
2. Type the following command to open the Grub2 configuration file in a text editor:

This command will open the configuration file in the Nano text editor. You may be prompted to enter your password, as this command requires administrative privileges.

3. In the configuration file, locate the line that starts with GRUB_CMDLINE_LINUX_DEFAULT.
4. Within the quotation marks after GRUB_CMDLINE_LINUX_DEFAULT, remove any mention of the zfs module. It may look something like this:

Remove the zfs=bootfs part, so it becomes:

5. Save the changes by pressing Ctrl + O and then exit the text editor by pressing Ctrl + X.
6. Update the Grub2 bootloader by running the following command:

This command will update the Grub2 configuration based on the changes you made in the previous steps.

That's it! You have successfully resolved the issue of Grub2 insisting on including the zfs module when it does not exist on your system.
