i installed the puppetlabs-lvm module which provides some custom facts like lvm_pv_0

having the warning($facts['lvm_pv_0']) in my site.pp correctly outputs /dev/md0 but runningfacter | grep lvm or puppet facts | grep lvm from command line does not return anything. i have not checked them all but it looks like that every custom fact is missing from the command line.

how to access the custom facts from the command line?


  • just for info:
  • puppet version: 4.8.1
  • os: debian 8 jessie
  • tested on: vagrant+virtualbox & bare metal

i run the commands as root, i already tried facter -p / facter --puppet. maybe my wording is wrong, not sure if custom facts are the same as "custom" facts from modules

in my example of the puppetlabs-lvm module, the facts are located in `modules/lvm/lib/facter/lvm_support.rb the facts are loaded and correctly accessible on a puppetrun in vagrant or when connected on a puppetmaster. only on the commandline the facts are missing.

the ommand puppet config print factpath has the following output for me /opt/puppetlabs/puppet/cache/lib/facter:/opt/puppetlabs/puppet/cache/facts both directories are empty. the directories given in a answer below/var/lib/puppet/lib/facter:/var/lib/puppet/facts does not exist.

extra question: where should custom facts be stored on a node?

solution for my problem was to add the environment to the call

puppet facts --environment puppet | grep lvm

I have also sometimes seen permissions or path issues on the custom facts.. I need to run 'sudo facter -p' OR (in a puppet 3.7.4 env) I need to use FACTERLIB=/var/lib/puppet/lib/facter:/var/lib/puppet/facts facter -p to see any custom facts from modules.

Let me know if either of those types of configurations help you.

The root/non-root difference could be seen in the factpath that is being used. If you run puppet config print factpath and sudo puppet config print factpath they probably point to different locations. You could use the 'root' puppet factpath as your FACTERLIB path when running facter as your regular user

The command I have been using is puppet facts find $certname --render-as yaml | grep $factname. Obviously you will need to change this for your machine's certificate. If you want to use the trailing pipe to grep, you will need to give an existing $factname, too.

Add -p to your facter run to show custom facts installed via Puppet modules.

Like this:

facter -p lvm_pv_0
