Hello all. Please guide me into to find out the impact a busy nfsd is having on the Linux page cache. Is it possible to determine which files have portions in the page cache? Secondly, files opened by nfs clients do not show up in lsof (or ftop) on the nfs server? Is there any way to list these open files and more importantly, observe the i/o to them?
