NFS Direct IO completely bypasses the client cache and is useful in situations where - The application does caching. - The application knows that the data read/written is not going to be accessed again anytime soon. I did stress testing of NFS direct IO, but need to replicate the environments/tests that you guys are seeing problems in. I am going to turn off NFS direct IO support till the problems are fixed. mohan
