Turn Off Journaling

How do I turn off journaling on my Raspberry PI 4 with Raspberry Pi OS?

Why on earth would you want to do that, its one of the key features in ext.

Here are the general steps to disable journaling on an ext4 file system: Backup Your Data: Before making any changes to the file system, it's crucial to back up your data. Disabling journaling carries risks, and having a backup ensures you can restore your data if something goes wrong. Check File System Type: Confirm that your file system is indeed ext4. You can use the following command:

bash
df -Th

Look for the entry corresponding to the partition you want to modify, and check the "Type" column to ensure it's ext4. Unmount the File System: You cannot modify a mounted file system, so unmount it first. Replace /dev/sdXn with the appropriate partition identifier.

bash
sudo umount /dev/sdXn

Disable Journaling: Run the following command to disable journaling. Replace /dev/sdXn with your partition identifier.

bash
sudo tune2fs -O ^has_journal /dev/sdXn

This command removes the has_journal feature from the file system. Check File System: Run a file system check to ensure everything is in order.

bash
sudo e2fsck -f /dev/sdXn

If prompted to fix issues, allow the tool to do so. Mount the File System: After making the changes, remount the file system.

bash
sudo mount /dev/sdXn /path/to/mountpoint

Remember to replace /dev/sdXn with the actual identifier of your partition, and /path/to/mountpoint with the path where the partition is normally mounted.
