Fascinating. I sit corrected. This only occurs for recursively submounted directories, e.g. /scratch/subdir1. cat /proc/fs/fscache/stats > file1 pv < /scratch/subdir1/testfile > /dev/null [50 MB of data fly by] cat /proc/fs/fscache/stats > file2 diff file1 file2 [no output] mount | grep /scratch manticore:/scratch on /scratch type nfs4 (rw,fsc,clientaddr=128.220.X.X,addr=128.220.X.Y) - Rich On Thu, May 21, 2009 at 10:09 AM, David Howells <dhowells@xxxxxxxxxx> wrote: > Rince <rincebrain@xxxxxxxxx> wrote: > >> If I mount /scratch with -t nfs4 -o rw,fsc, and do ~50 MB of IO, I get the >> same: > > Can you describe the IO you're doing?
