           Summary: nfs filesystem not updating
           Product: kde
           Version: unspecified
          Platform: Ubuntu Packages
        OS/Version: unspecified
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: unassigned-bugs at kde.org
        ReportedBy: dmonty at sd73.bc.ca


Version:            (using KDE 4.4.0)
Installed from:    Ubuntu Packages

We are running approximately 3200 diskless workstations with kde3.5.  I would
like to upgrade to kde4.x but in testing I've noticed the following bug:

If I update any files on the main central server the kde4 client workstations
do not see the update. If I create or delete a file on the client workstation
only the client workstation sees the change (probably inotify).

On our kde3.5 systems the changes on the server are picked up in kde by gamin.
 /etc/gamin/gaminrc
 fsset nfs poll 10

But this doesn't work in kde4 series.
Here is what I've tried so far:
* Started testing with a fresh kubuntu 9.10 install.
* Upgraded to kde4.4 from kubuntu ppa.
* Tried switching from gamin to fam.
* Tried on a non-diskless computer kde4.4.0 mounting a folder over nfs - same
problem.
* Tried manually running /usr/lib/gamin/gam_server

Here is how to duplicate the problem:
server: aptitude install nfs-kernel-server portmap
server: /etc/exports
 /home  CLIENT_IP(rw,no_root_squash,async,subtree_check)
server: /etc/init.d/nfs-kernel-server reload
client: aptitude install portmap nfs-common
client: mount SERVER_IP:/var /mnt
client: # open up a kde app like Dolphin and browse to /mnt
server: touch that
client: # you will not see "that" file in Dolphin unless you manually press the
reload/refresh button.

==
Again in kde3.5 i could install a software program on the server and kde would
see the change (/usr/share/applications/WHATEVER.desktop) and immediately add
it to the menu.  We could create a file in the home folder and all users would
immediately see it.  This functionality appears to be broken in kde4.x.x.
