Re: nfs client performance while server is down

So? I don't see why that would be an NFS problem.

As far as I can see from this thread, you are basically asking us to fix
these broken applications by implementing a "disconnected NFS" mode.
While that may indeed be a cool thing to support, I haven't seen anybody
so far stepping up and saying that they have the time and resources to
work on it. Are you volunteering?
