Thanks a lot. Actually, it was nmon that put me onto looking into this.I was finding no difference in its reports when using f/s different block size and that's when the "??????" started to show on the top of my head! Still planning to look at strace to see if I can figure out MOL what is going on. More later.

Maybe ... Assuming you haven't stumbled onto it on your own that is.
