umount trouble

[linmix]

I need to work on a borrowed laptop for a few days and have Aurox 9.4 installed (based on fc2)

I needed to make a small change in fstab to view special characters in file names (added
'utf8') and wanted to check it worked. So I tried to umount the volume and got:

# umount /dev/hda1
umount: /mnt/windows/c: device is busy

Funny thing is I *can* umount a second windows partition that's mounted in the same way. So I tried

# /sbin/fuser -k /devhda1

But still get no result.

I checked if maybe it was something related to the symlinks present to hda1 and created a few to hda2, but hda2 umounts fine even with symlinks (though it improbable to be the cause, but hey, why discard anything when you can't find the cause).

Only shared files are accessed to the links (no apps located there) so I don't see how hda1 could be busy.

All nautilus windows are closed, nothing but a terminal window opened (in gnome). Funnier still, I've tried logging in as root into gnome and umount and I get the same 'busy' message.

How can I find out why hda1 is busy?

In addition, I cannot write to hda1 as normal user (using nautilus or gedit, e.g.) but Audacity *will* save files to hda1?! hda2 pesents me with no problems...

For the mortally curious among you, here are the corresponding fstab entries:

/dev/hda1               /mnt/windows/c          vfat    defaults,utf8,users,umask=0000  0 0
/dev/hda2               /mnt/windows/d          vfat    defaults,utf8,users,umask=0000  0 0

Try lsof (list open files):

lsof | grep /mnt/windows/c

[linmix]

# lsof | grep /mnt/windows/c
fam 5383 root 19r DIR 3,1 16384 269 /mnt/windows/c/.Trash-root

at least that's what I get right after logging in. If I open nautilus and browse a folder on the c partition and close it again. +after closing+ I get:

# lsof | grep /mnt/windows/c
fam 5383 root 19r DIR 3,1 16384 269 /mnt/windows/c/.Trash-root
fam 5383 root 47r DIR 3,1 16384 6 /mnt/windows/c/Documents and Settings/Olga/Mis documentos/Mi m\xc3\xbasica

Now what! How do I stop these accesses and umount the partition?

[SangFroid75]

try:

/etc/init.d/famd stop

prior to unmounting the partition.

Do you have a console window, a file manager etc with the current directory on the problematic drive open?

[linmix]

nop, only thing open is a terminal at ~

try
# /sbin/fuser -km /devhda1

You do not see all the process because you are missing the -m options
