I discovered this repeatable anomaly using Linux Version 2.4.18
and mount version "mount-2.10o".

If file-systems are mounted upon boot with 'defaults' as options

like /etc/fstab...

# device			directory	type	options	freq pass
# -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
/dev/sdb1			/		ext2	defaults  0   1
/dev/sdc1			/alt		ext2	defaults  0   2
/dev/sdb2			none		swap	defaults  0	2
/dev/sdc2			none		swap	defaults  0	2
/dev/sdc3			/home/users	ext2	defaults  0	2	
none				/proc		proc	defaults  0	2
/dev/sda1			/dos/drive_C	msdos	defaults  0     2
/dev/sda5			/dos/drive_D	msdos	defaults  0     2

Then I execute:

mount -o remount,rw,noatime /
mount -o remount,rw,noatime /alt
mount -o remount,rw,noatime /home/users

The result is (correctly)

cat /proc/mounts

/dev/root.old /initrd ext2 rw 0 0
/dev/root / ext2 rw,noatime 0 0
/dev/sdc1 /alt ext2 rw,noatime 0 0
/dev/sdc3 /home/users ext2 rw,noatime 0 0
none /proc proc rw 0 0
/dev/sda1 /dos/drive_C msdos rw 0 0
/dev/sda5 /dos/drive_D msdos rw 0 0

Now, if I shut down the system, properly dismounting all the drives,
then I reboot, the drives that were re-mounted end up being fscked
due to 'was not cleanly unmounted' inference. Nothing wrong is found.

Now, if I mount the drives "noatime" from the start, i.e., from
/etc/fstab upon startup, there are no such errors upon re-boot.

There is something going wrong during 'remount' that makes e2fsck
'think' that the drives were not cleanly dismounted.

Is this a known problem, fixed in later versions?

Cheers,
Dick Johnson

There was once a problem that if you mounted a filesystem and crashed
shortly thereafter the filesystem would mistakenly be marked clean and
not checked when it should be, but I haven't heard the opposite problem.

I did a quick check (just mounting an ext2 filesystem on 2.4.18 from bash,
remounting, then unmounting) and everything worked as expected.  Could
you try doing your test and running "dumpe2fs -h /dev/foo" between each
step to check the filesystem state.  It should be "not clean" until the
filesystem is unmounted, at which point it should be "clean".

Also try doing the unmount steps manually before shutdown to see if it
is a timing issue.  If you have writeback cache enabled on your disks
and this is not being flushed to the oxide before power is lost you may
not just be having an fsck problem, but also a data loss/corruption
problem.

Cheers, Andreas

If I don't remount with 'noatime' I don't get the unclean error
upon startup. /dev/sdc3 was clean (for some reason) while the
othet two were dirty.

Well, I don't know what to say about this...  The unmount path calls
ext2_put_super(), which marks the superblock clean and calls
ext2_sync_super() to force it to disk (this can be seen from debugfs
output).

On reboot the filesystem is not clean.  Either the kernel is not
doing what it should to flush the dirty superblock to disk, or the disk
is lying about having written the superblock to disk.  I would suspect
the latter on IDE drives, but SCSI drives are usually sane.

Try adding a sync or two before rebooting, and also checking via
debugfs after reboot to ensure it is marked dirty when it shouldn't
be.  You could even add some printk's to ext2_put_super() inside the
conditional where it marks the filesystem clean and syncs the super
to ensure that is being called.

What about the above message?

The fact that /dev/sda1 is your root fs could cause some strangeness also.

It would appear to be that ext2_remount() is missing "sb->s_flags |=
MS_RDONLY" after the comment "set the rdonly flag and then mark the
partition as valid again".  The other check for valid flags also appears
to be a bit suspect.

Cheers, Andreas

That's because I have a floppy (with typescript) mounted rw on
/mnt and the file is still open (that's how these messages are
recorded).

I will look around a bit. This only happens when one remounts an
already-mounted file-system, then dismounts it. Normally everything
is clean. This is not something that would normally happen.  Oh... I
forgot... This is a SMP machine
