A plugin for Chef::Knife which displays nodes that are probably dead.
We define "dead" as :
- last seen by the server more than 24 hours ago
- node[:fqdn] does not resolve
- inode[:ipaddress] do not answer to ping
Of course, in your environment it's totally possible for a node to fail these tests and still be non-dead.
Ask for the list of dead nodes:
% knife node deadnodes
FIXME give examples!
knife-deadnodes is available on rubygems.org - if you have that source in your gemrc, you can simply use:
gem install knife-deadnodes
FIXME: this is false (for now!). Copy the plugins at the right places for now!
