Hello, I agree with Craig 100%.
The experience we have had with different NFS versions/configurations in Linux in
the past , tells us that this is not a reliable solution for databases.
Others will say the oposite, but running PostgreSQL via NFS in Linux is from my
point of view, a disaster waiting to happen. I have to say too that we have not
tried this lately and that maybe things have improved since last time we testet.
