I've had issues like this as well. Fortunately Eric Schrock and Adam Leventhal work down the all from me and I ran this past them. Eric had the suggestion to simply do a "find" from the directory that I'm interested in getting file names for and that did the trick. For example all of my tracing is on
/domain0 so I simply do $ cd /domain0 $ find . > /dev/null and then do my tracing. Since adding this trick, I haven't had problems with "unknown" - Kyle Hailey O: +1.415.341.3430 F: +1.650.494.1676 275 Middlefield Road, Suite 50 Menlo Park, CA 94025 http://www.delphix.com On Wed, Jul 20, 2011 at 9:20 AM, David Pacheco <d...@joyent.com> wrote: > On Wed, Jul 20, 2011 at 7:10 AM, wessels <wessels...@gmail.com> wrote: > >> I'm issuing the following statement on a ONNV_104 (I know a bit old >> but very stable) NFS server: >> # dtrace -n 'nfsv3:::op-read-start,nfsv3:::op-write-start >> {@[probefunc,args[1]->noi_curpath]=count(); }' >> >> which works fine...most of the time but not always. >> Usually it resolve's the filenames on which the I/O are done but not >> always.
