I am running openSUSE 11.2.
KDE makes a lot of KDE apps and also other as yast, openoffice etc lock a
file system so I not can unmount it.

All our computers have a link from their ~/Documents, ~/Downloads etc to
common document, download, etc ... partitions. This is because we are
working with several distros/versions and always want our
documents/downloads at hand.

However for some reasons I do not understand, KDE makes apps locking the
Documents mount points so this partition not can be unmounted. This is a
KDE behaviour and I have not the same problem with other window
managers.

Each user directory has a link like
Documents -> /local/Documents/$USER

/local/Documents is a mount point for a local/remote partition.
lsof shows that when running KDE the /local/Documents/ is kept open and
makes the file system busy. Does this also imply that there MUST be a
directory called Documents if you are to run KDE? The other linked file
systems are not affected. I have not had time to test this yet. Because
it does not lock /usr/Documents/user which would be more understandable.

Maybe you can find out which process is accessing the directory, e.g. by
using fuser

Yes I have used fuser. That is why I say all kde apps + a lot more.
IE klauncher, kded4, kgglobalc, knotify4, plasma-de, kio_file, kaccess, kxkb,
nepomukse, krunner, kmix, kalarm, kgps, kget, polkit-gn, kupdateap, klipper,
konsol, . . . and such as yast, openoffice and other running apps.
Now I did check again. I would say that every running program have the
directory open if I use KDE.
What are all this apps doing in /local/Documents.
If they had followed the link I could have understood but am still
questioning, what do they have to do here?

Is this a bug or by intention?

So all apps hold an equivalent to /home open ??
A ls here will looks the same as ls /home.
However this might never be used as I as my knowledge not have heard any
complaints that documents go to this directory. But on the other hand I am
perhaps the only one using KDE now. All others have changed to other window
managers.

Perhaps this is related to the problems KDE has to keep track of following
links. I has the tendency to change to the real patch instead. This cause
sever problems and the user have to be very alert.



Cheers,
Kevin
