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

Solution Verified - Updated -

Issue

  • If a ext file system has no journal, commands such as tune2fs or dumpe2fs shows the file system state as not clean while being mounted.
#tune2fs -l /dev/mapper/localvg-ext4 | grep "^Filesystem state"
Filesystem state:         not clean
  • Unmounting the file system reset the flag to clean
