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
