rake aborted!

I get the following error while running rake db:migrate

rake aborted!
undefined method `reenable' for <Rake::Task db:schema:dump => [environment]>:Rake::Task

this means you have an old version of rake (older than 0.87), you can verify it by typing:

rake --version

Usually this error is "safe" to ignore, however, it is recommended to upgrade to rake >= 0.87

Unable to save: failed to detect boot server: getaddrinfo: Name or service not known

if you have registred your smart-proxys via name, and these name are not resolvable, you get this error, you can add the name to your dns server or set
:tftp_servername: in smart-proxy settings to the ip of the smart-proxy.

I use puppet enterprise, what now?

As of PE version 1.0, foreman won't install easily without a few modifications. Since PE ships with its own version of Ruby you will need to install a few gems.
Basically you need to tell foreman to use the PE provided ruby library instead. Your not required to run the puppet version of ruby either as many distros now ship with ruby 1.8.7.

  1. You first need to install the pe-ruby-devel package that ships with PE. You can find this in your packages folder wherever you extracted PE.
    a. rpm -ivh pe-ruby-devel-1.8.7.302-1.el5.i386.rpm
  2. Update your path variable to use the ruby version PE ships with (export PATH=/opt/puppet/bin:$PATH)
  3. Check to make sure your PATH was updated ("which gem" should return /opt/puppet/bin/gem)
  4. gem install json
  5. gem install rest-client
    (install the gem database driver you use)
  6. gem install sqlite3 or gem install mysql ( you may have additional dependencies that would need to be resolved first)

Some of the gem dependencies can be resolved by installing the development library for that package (example: mysql-devel)

I found it difficult to install the sqlite3 gem because of dependency hell so I just setup mysql instead which was far easier to setup. Additionally mysql is much more scalable than sqlite.

You can get a list of the currently installed gems by using: gem list.

If your running the foreman init script or /etc/sysconfig/foreman configuration file. You may need to update apache/passenger configurations that point to the PE ruby version.

error: Entry 'some file' not uptodate. Cannot merge.

If you downloaded Foreman from source (git), it could be that some of the files you have modified (or were modified automatically) conflicts with another file Foreman wants to upgrade.

If you don't think that you edited this file (e.g. db/schema.rb) it is usually safe to do:

git checkout 'some file'

This will revert the file to its previous condition (as in the repo at the time of checkout) and now you should be able to get the latest version by:

git pull

Strange errors with passenger

Passenger executes foreman, based on the owner of the config/environmnets.rb file, make sure that this use can actually access:
  • puppet configuration files
  • sqlite database (if using sqlite)
  • write to log, tmp directories

see source:extras/puppet/foreman for complete puppet based setup for Foreman.

error: Could not send facts to Foreman: wrong Content-Length format (RuntimeError)

You might see this error if you run the HTTP push facts script or the sample external nodes script.
This is most likely due to older version of the mongrel gem. Please try and update your gems.

gem update mongrel

Is my Foreman instance running?

There is simple status service that returns JSON with "result" message "ok" when the instance is up and running. It also "pings" database and returns lag. Example:

$ curl -k -H "Accept: application/json" http://instance:3000/status
{"status":200,"result":"ok","db_duration_ms":"5"}

How do I enable debugging?

Edit config/environments/production.rb and uncomment "config.log_level = :debug"

Your activerecord Version is to new, you need activrecord 3.0.10 see http://projects.puppetlabs.com/issues/9290

gem uninstall activerecord
gem install activerecord -v 3.0.10

How do I fix this error: "Unable to find directory $confdir/environments/$environment/modules in environment master" ?

If you've followed http://docs.puppetlabs.com/guides/environment.html#configuring-environments-on-the-puppet-master to
create a multi-environment puppet configuration, you're initial rake may look something like this:

rake puppet:import:puppet_classes RAILS_ENV=production
(in /usr/share/foreman)
Evaluating possible changes to your installation
Problems were detected during the evaluation phase

Unable to find directory $confdir/environments/$environment/modules in environment master

Please fix these issues and try again

This is because Foreman does not currently evaluate $confdir. There is a feature request open on this issue. In the
meantime, hard code your $confdir in your puppet.conf.

Smart-proxy do not recognize my puppet environment

If I query smart-proxy and it return empty puppet environment :

curl -k -H "Content-Type:application/json" -H "Accept:application/json" http://puppet:8443/puppet/environments
=> []

You may have to add in your puppetmaster's puppet.conf environment definition like :

[production]
    manifest   = /etc/puppet/manifests/site.pp
    modulepath = /etc/puppet/modules
    fileserverconfig = /etc/puppet/fileserver.conf
    templatedir=/etc/puppet/templates/

[preprod]
    manifest   = /etc/puppet/preprod/manifests/site.pp
    modulepath = /etc/puppet/preprod/modules
    fileserverconfig = /etc/puppet/preprod/fileserver.conf
    templatedir=/etc/puppet/preprod/templates

[development]
    manifest   = /etc/puppet/development/manifests/site.pp
    modulepath = /etc/puppet/development/modules
    fileserverconfig = /etc/puppet/development/fileserver.conf
    templatedir=/etc/puppet/development/templates/

[test]
    manifest   = /etc/puppet/test/manifests/site.pp
    modulepath = /etc/puppet/test/modules
    fileserverconfig = /etc/puppet/test/fileserver.conf
    templatedir=/etc/puppet/test/templates/

How do I fix the puppet class import problem with multiple puppet environment ?

If Foreman don't seems to be aware of all your environment and is able to import only your "production" environment (see http://theforeman.org/issues/1159),
try to add ":puppetconfdir: /etc/puppet/puppet.conf" in your settings.yaml.

Unable to connect to Hypervisor?

Make sure the user that's actually running foreman can connect to your remote hypervisor (for instance by running sudo -u foreman virsh -c qemu+ssh://root@<host>/session list).

If you are running foreman through phusion passenger, ps auxwwf | grep "R[a]ils: /usr/share/foreman" | awk '{ print $1 }' will give you the user that's running foreman. If you find that it's not being run by foreman, do the following:
cd ~foreman
chown foreman config/environment.rb
touch ~foreman/tmp/restart.txt

Routing errors when running rake test?

Edit the config/settings.yaml and set the :login: setting to true

cannot load such file -- facter / puppet (LoadError)

if you running foreman under RVM or custom ruby installation, you would need to get puppet installed as a gem (as puppet / facter packages are not in your ruby search path).

simply add another file to FOREMAN_DIR/bundler.d

echo "gem 'puppet'" > bundler.d/local-gems.rb

Causes of "Error 400 Bad Request", and other smart-proxy related errors in the Foreman interface:

  • Check the sudoers file on the proxy if user "foreman-proxy" can "puppetca". The command puppetca is un-available in puppet 3.0. Workaround is to create a wrapper script.
  • Check if Bind is listening on 127.0.0.1. The proxy connects to localhost only, so this is required.
  • Check if the foreman-proxy user "foreman-proxy" can read the Bind rndc keys.
  • From the cmd line, check if the user can run "puppetca" and "nsupdate" properly.
  • In Ubuntu, you will have to tell apparmor to allow Bind to write to zone files. If your zone files are in /etc/bind/zones/, add "/etc/bind/zones/** rw," to /etc/apparmor.d/usr.sbin.named.
  • If using Ubuntu Libvirt, and the "Virtual Machine" tab is empty, then you most likely need to create a default storage pool:
    cat /etc/libvirt/storage/default.xml 
    <pool type='dir'>
      <name>default</name>
      <uuid>35e0bbce-4019-ca88-6dec-b1a0c1be774b</uuid>
      <capacity>0</capacity>
      <allocation>0</allocation>
      <available>0</available>
      <source>
      </source>
      <target>
        <path>/var/lib/libvirt/images</path>
        <permissions>
          <mode>0700</mode>
          <owner>-1</owner>
          <group>-1</group>
        </permissions>
      </target>
    </pool>
    
  • On Ubuntu Libvirt, you may have to change /etc/libvirt/libvirtd.conf to listen on TCP.
