PE known issues

Sections

These are the known issues in PE 2019.8.

Installation and upgrade known issues

These are the known issues for installation and upgrade in this release.

Upgrade fails with an unenabled replica

PE upgrade fails if you have a provisioned, but not enabled, replica. As a workaround, edit the PE Master node group configuration with these parameters for the puppet_enterprise::profile::master class:
  • puppetdb_port = [8081]
  • puppetdb_host = ["MASTERS_FQDN_EXAMPLE"]

Upgrades can fail when using custom database certificate parameters

When upgrading an infrastructure with an unmanaged PostgreSQL database to this version of PE, the upgrade can fail and result in downtime if the databases use custom certificates not issued by the PE certificate authority. This is the case even if you configured the database_properties parameters in pe.conf to set a custom sslrootcert. The upgrader ignores these custom certificate settings.

To manually override the upgrader's certificate settings, run these commands, replacing <NEW CERT> with the name of your custom certificate.
rpm -iUv /opt/puppetlabs/server/data/packages/public/2019.3.0/el-7-x86_64-6.12.0/pe-modules-2019.3.0.2-1.el7.x86_64.rpm
                    
sed -i 's#/etc/puppetlabs/puppet/ssl/certs/ca.pem#/etc/puppetlabs/puppet/ssl/<NEW CERT>.pem#'
/opt/puppetlabs/server/data/environments/enterprise/modules/pe_manager/lib/puppet_x/puppetlabs/meep/configure/postgres.rb
                        
./puppet-enterprise-installer - --force
Note: The first step in the code block above includes paths specific to the PE version you're upgrading to. Replace these version information as needed.

Converting legacy compilers fails with an external certificate authority

If you use an external certificate authority (CA), the puppet infrastructure run convert_legacy_compiler command fails with an error during the certificate-signing step.
Agent_cert_regen: ERROR: Failed to regenerate agent certificate on node <compiler-node.domain.com>
Agent_cert_regen: bolt/run-failure:Plan aborted: run_task 'enterprise_tasks::sign' failed on 1 target
Agent_cert_regen: puppetlabs.sign/sign-cert-failed Could not sign request for host with certname <compiler-node.domain.com> using caserver <master-host.domain.com>
To work around this issue when it appears:
  1. Log on to the CA server and manually sign certificates for the compiler.
  2. On the compiler, run Puppet: puppet agent -t
  3. Unpin the compiler from PE Master group, either from the console, or from the CLI using the command: /opt/puppetlabs/bin/puppet resource pe_node_group "PE Master" unpinned="<COMPILER_FQDN>"
  4. On your master, in the pe.conf file, remove the entry puppet_enterprise::profile::database::private_temp_puppetdb_host
  5. If you have an external PE-PostgreSQL node, run Puppet on that node: puppet agent -t
  6. Run Puppet on your master: puppet agent -t
  7. Run Puppet on all compilers: puppet agent -t

Disaster recovery known issues

These are the known issues for disaster recovery in this release.

Upgrade fails with an unenabled replica

PE upgrade fails if you have a provisioned, but not enabled, replica. As a workaround, edit the PE Master node group configuration with these parameters for the puppet_enterprise::profile::master class:
  • puppetdb_port = [8081]
  • puppetdb_host = ["MASTERS_FQDN_EXAMPLE"]

Puppet runs can take longer than expected in failover scenarios

In disaster recovery environments with a provisioned replica, if the master is unreachable, a Puppet run using data from the replica can take up to three times as long as expected (for example, 6 minutes versus 2 minutes).

FIPS known issues

These are the known issues with supported platforms in this release.

Puppet Server FIPS installations don’t support Ruby’s OpenSSL module

FIPS-compliant installations don't support extensions that use the standard Ruby Open SSL library, such as heira-eyaml.

Errors when using puppet code and puppet db commands on FIPS-enabled hardware

When the pe-client-tools packages are run on FIPS-enabled hardware, puppet code and puppet db commands fail with SSL handshake errors. To use puppet db commands on a FIPS-enabled machine, install the puppetdb_cli Ruby gem with the following command:
/opt/puppetlabs/puppet/bin/gem install puppetdb_cli --bindir /opt/puppetlabs/bin/
To use puppet code commands on a FIPS-enabled machine, use the Code Manager API. Alternatively, you can use pe-client-tools on a non-FIPS-enabled machine to access a FIPS-enabled master.

Configuration and maintenance known issues

These are the known issues for configuration and maintenance in this release.

Console is inaccessible with PE set to IPv6

If you specify IPv6, PE Java services still listens to the IPv4 localhost. This mismatch can prevent access to the console as Nginx proxies traffic to the wrong localhost.

As a workaround, set the java.net.preferIPv6Addresses property to true for console services and PuppetDB:
"puppet_enterprise::profile::console::java_args": {
  "Xms": "256m"
  "Xmx": "256m"
  "Djava.net.preferIPv6Addresses": "=true"
}
 
"puppet_enterprise::profile::puppetdb::java_args": {
  "Xms": "256m"
  "Xmx": "256m"
  "Djava.net.preferIPv6Addresses": "=true"
}

puppet infrastructure recover_configuration misreports success if specified environment doesn't exist

If you specify an invalid environment when running puppet infrastructure recover_configuration, the system erroneously reports that the environment's configuration was saved.

puppet-backup fails if gems are missing from the master's agent environment

The puppet-backup create command might fail if any gem installed on the Puppet Server isn't present on the agent environment on the master. If the gem is either absent or of a different version on the master's agent environment, you get the error "command puppet infrastructure recover_configuration failed".

To fix this, install missing or incorrectly versioned gems on the master's agent environment. To find which gems are causing the error, check the backup logs for gem incompatibility issues with the error message. PE creates backup logs as a report.txt whenever you run a puppet-backup command.

To see what gems and their versions you have installed on your Puppet Server, run the command puppetserver gem list . To see what gems are installed in the agent environment on your master, run /opt/puppetlabs/puppet/bin/gem list.

Orchestration services known issues

These are the known issues for the orchestration services in this release.

The function puppet plan show displays invalid plans when Code Manager is disabled

If Code Manager is disabled, the puppet plan show function and the console will still list plans that are contained in a control repo, but those plans cannot be run. Enable Code Manager to run plans.

Running plans during code deployment can result in failures

If a plan is running during a code deployment, things like compiling apply block statements or downloading and running tasks that are part of a plan might fail. This is because plans run on a combination of PE services, like orchestrator and puppetserver, and the code each service is acting on might get temporarily out of sync during a code deployment.

Master reporting HTTP error after Qualys scan

When running a Qualys scan, the master reports the error "HTTP Security Header Not Detected. Issue at Port 443".

Code management known issues

These are the known issues for Code Manager, r10k, and file sync in this release.

Default SSH URL with TFS fails with Rugged error

Using the default SSH URL with Microsoft Team Foundation Server (TFS) with the rugged provider causes an error of "unable to determine current branches for Git source." This is because the rugged provider expects an @ symbol in the URL format.

To work around this error, replace ssh:// in the default URL with git@

For example, change:
ssh://tfs.puppet.com:22/tfs/DefaultCollection/Puppet/_git/control-repo
to
git@tfs.puppet.com:22/tfs/DefaultCollection/Puppet/_git/control-repo

GitHub security updates might cause errors with shellgit

GitHub has disabled TLSv1, TLSv1.1 and some SSH cipher suites, which can cause automation using older crypto libraries to start failing. If you are using Code Manager or r10k with the shellgit provider enabled, you might see negotiation errors on some platforms when fetching modules from the Forge. To resolve these errors, switch your configuration to use the rugged provider, or fix shellgit by updating your OS package.

Timeouts when using --wait with large deployments or geographically dispersed compilers

Because the --wait flag deploys code to all compilers before returning results, some deployments with a large node count or compilers spread across a large geographic area might experience a timeout. Work around this issue by adjusting the timeouts_sync parameter.

r10k with the Rugged provider can develop a bloated cache

If you use the rugged provider for r10k, repository pruning is not supported. As a result, if you use many short-lived branches, over time the local r10k cache can become bloated and take up significant disk space.

If you encounter this issue, run git-gc periodically on any cached repo that is using a large amount of disk space in the cachedir. Alternately, use the shellgit provider, which automatically garbage collects the repos according to the normal Git CLI rules.

Code Manager and r10k do not identify the default branch for module repositories

When you use Code Manager or r10k to deploy modules from a Git source, the default branch of the source repository is always assumed to be master. If the module repository uses a default branch that is not master, an error occurs. To work around this issue, specify the default branch with the ref: key in your Puppetfile.

After an error during the initial run of file sync, Puppet Server won't start

The first time you run Code Manager and file sync on a master, an error can occur that prevents Puppet Server from starting. To work around this issue:

  1. Stop the pe-puppetserver service.
  2. Locate the data-dir variable in /etc/puppetlabs/puppetserver/conf.d/file-sync.conf.
  3. Remove the directory.
  4. Start the pe-puppetserver service.

Repeat these steps on each master exhibiting the same symptoms, including any compilers.

Puppet Server crashes if file sync can't write to the live code directory

If the live code directory contains content that file sync didn’t expect to find there (for example, someone has made changes directly to the live code directory), Puppet Server crashes.

The following error appears in puppetserver.log:

2016-05-05 11:57:06,042 ERROR [clojure-agent-send-off-pool-0] [p.e.s.f.file-sync-client-core] Fatal error during file sync, requesting shutdown.
org.eclipse.jgit.api.errors.JGitInternalException: Could not delete file /etc/puppetlabs/code/environments/development
        at org.eclipse.jgit.api.CleanCommand.call(CleanCommand.java:138) ~[puppet-server-release.jar:na]

To recover from this error:

  1. Delete the environments in code dir: find /etc/puppetlabs/code -mindepth 1 -delete
  2. Start the pe-puppetserver service: puppet resource service pe-puppetserver ensure=running
  3. Trigger a Code Manager run by your usual method.
