However, mfs has a maximum size of 512M. md appears to have a very small maximum size and only resides in core vn (somewhat depricated) appears only to reside in a file The behaviour I desire is that the files will stay in memory aggressively and not block writes (thus slowing it down) as much as possible. Is there a way to tune NFS to do this? Is there a way to have a swap-backed memory disk that is large?
