Ubuntu /boot partition stay in mode "Filesystem state: not clean" (tune2fs)

Octeny asked:

I have the problem with my /boot partition on a ubuntu “Ubuntu 11.10” system. Maybe also on “Ubuntu 12.04 lts” but I cannot verify this, because it’s a prodctive system.

If I umount the /boot partition, make a fsck.ext2 everything seem ok, see the log.

But if I remount the /boot everything is pretty much the same as before, tune2fs shows ‘state : not clean’

What do I wrong and more important can I do something without rebooting the system?

Best Regards,

The situation:

Mount-Point
# mount -v | grep "^/" | awk '{print "nPartition identifier: " $1  "n Mountpoint: "  $3}'
Partition identifier: /dev/mapper/nvidia_fjdedcdd1
Mountpoint: /boot

# tune2fs -l /dev/mapper/nvidia_fjdedcdd1 | grep -iE '(state|error)'
Filesystem state:         not clean
Errors behavior:          Continue

# umount /boot

# fsck.ext2 -f /dev/mapper/nvidia_fjdedcdd1

# tune2fs -l /dev/mapper/nvidia_fjdedcdd1 | grep -iE '(state|error)'

My answer:


This is normal. The filesystem is always “not clean” while it is mounted. There is no problem to be fixed.
