Thread: KDE hangs when nfs connection is lost

  1. #1

    Default KDE hangs when nfs connection is lost

    This is the situation:
    I have a server which is located in the basement. The server exports a few directories which I mount on my desktop using NFS. From time to time, the connection gets lost. The server is also not always on. I can't change that part, so I worked out a script which notifies me when it's going down, and when it's back up again. It also mounts everything back.

    However.. As soon as I loose the connection, my desktop seems to be gone. KDE doesn't work, but I can use a few applications like Konsole, google-chrome, firefox, stuff like that. But the plasma-desktop around it hangs.

    As soon as the connection gets back again, everything works. I have this issue only when my desktop is running while I loose the connection to the server. If it's down when I start my desktop, everything works properly. Unless the server comes alive, the nfs directories are mounted and the connection is lost again.

    My hardware:

    Perhaps you should mount them somewhere else other than the Desktop directory and have symlinks from your desktop.

    Default Re: KDE hangs when nfs connection is lost

    It depends of course on what those "few directories" are and if they are used when the connection fails.

    When you start e.g. and editor when it is not mounted, the editor will simply sya that the file is not found.
    But when you are editing and the connection fails all sorts of time out and retry mechanisms start their jobs.
