Ext4 filesystem without journal shows as "not clean" while being mounted

Solution Verified - Updated -

Issue

  • When an ext4 filesystem without a journal is mounted, commands such as tune2fs or dumpe2fs report its state as not clean:

    # tune2fs -l /dev/device-name |grep "^Filesystem state"
Filesystem state: not clean

  • After the filesystem is unmounted, its state returns to clean.
