Hello,
Thank you for the information . I understood you never recommend the case.
I have another question. I also use Linux in the case.
There are NFS mount options , noac and sync which is concerned with
caching.
Which option means the keyword 'without caching' in the manual.?
And the case you tested, which option you use when mounting.
Thank you very much.
Shikase.

If I mount the database cluster with caching in my environment, What kind of
problem I will meet? Please give the information about the problem you met.
It varies so much by NFS implementation and version that it is really
hard to say.
Personally, I would never, EVER run a database of any kind over nfs, but
perhaps I'm just scarred by Linux's NFS implementation.
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.
