Subject: Side effects of having NFSv4 mounted over udp
Date: Mon, 13 Dec 2010 08:46:24 +0100	[thread overview]
Message-ID: <4D05CF50.1010305@cea.fr> (raw)

Hi,

I know NFSv4 is definitely a connection oriented protocol, but noting 
prevent from using "mount -t nfs4 -o proto=udp <...>". Using TCP instead 
of UDP could be of great interest, especially in a HPC context where 
thousands of clients will operate at the same time. If a nfs mount point 
is made over udp, what would be the side effects ? I tried to run the 
connectathon on such a udp based mount point and I could find no errors. 
Is NFSv4/UDP a suitable solution ? Or does it make no sense to use udp ?

Thanks in advance for your answer.

    Regards

       Philippe
