Howdy! I have some diskless machines that boot using PXE and mount data over NFS. They are truly diskless. When I run vmstat (or similarly systat -vm) I get vmstat: getdevs: error getting device stats getdevs: Invalid argument Other PXE booted machines that mount hard drives don't exhibit this behavior. On machines that don't mount hard drives the sysctl variable kern.devstat.numdevs = 0 A ktrace on vmstat shows that a call to sysctl fails. What is to be done to be able to run vmstat and systat -vm? Or what are the consequences of this. if any? Freebsd-9-STABLE. thanx - steve
