Just fyi, I have committed r337962 to head, which stops the pNFS service from creating non-zero length empty files. Since these files were the ones causing the "ffs_truncate3" panics, the pan= ics should no longer occur. I will take a closer look at some point to see if I can spot why the panics= () occur and can easily revert this patch on my test setup if others have suggested patches to try related to this. Thanks for your help with this, rick
