Hi
Is there a way to disable Linux NFS client data caching (NOT attributes)?

'man 2 open'. Read all about O_DIRECT.

Thanks for the suggestion. I tried the O_DIRECT option with O_RDONLY, and i
am still seeing a lot of reads not hitting the server, looks like they are
being handled locally still. I've got the sizes and addresses page aligned.
Is there anything else that needs to be done to bypass the caching?
Thx,
Murali

No. O_DIRECT will cause every read to be sent to the server.
