NFS mounted disk owner

[Database Administrator]

Who should be ( performance wise ) the file system owner mounted as
NFS between two hosts . The Reader or the Writer process?
EG.
HostA owns FS ------> HostB sees FS ..
Should processes in HostA be writers and processes in HostB the
Readers?
Thank you.

Its a local disk on HostA, which must be "exported". On HostB, its
mounted.

I don't understand what you mean by "Reader" or "Writer" process in
this context.

Are you asking about user mode implementations of NFS
compared to kernel mode implementations, or do you have
some strange notion of how NFS works without having read
any of the documentation?

NFS is a filesystem so it *implements* ownership of files and
mount points.
