How to convert back Linux ext3 file system to ext2 file system

It is generally not recommended to convert an ext3 file system back to ext2, as ext3 provides several enhancements over ext2, such as journaling and support for larger file sizes. However, if you still want to convert an ext3 file system to ext2, you can follow these steps:

1. Unmount the ext3 file system by running the following command:

umount /path/to/filesystem

Replace /path/to/filesystem with the path to the ext3 file system.

2. Convert the file system to ext2 using the tune2fs command:

tune2fs -O ^has_journal /dev/<device>

Replace /dev/<device> with the device name of the ext3 file system.

3. Remount the file system:

mount /path/to/filesystem

Note that this process will remove the journal from the file system, which means that any data that was not written to the file system before the journal was removed may be lost. Therefore, it is important to make a backup of the file system before proceeding.
