PE known issues

These are the known issues in PE 2021.4.

Installation and upgrade known issues

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

Initial agent run after upgrade can fail with many environments

In installations with many environments, where file sync can take several minutes, the orchestration service fails to reload during the first post-upgrade Puppet run. As a workaround, re-run the Puppet agent until the orchestration service loads properly. To prevent encountering this error, you can clean up unused environments before upgrading, and wait several minutes after the installer completes to run the agent.

Installing or upgrading agents using TLSv1 fails with older OpenSSL versions

Script-based agent installation or upgrade on nodes that use TLSv1 can fail if the curl version installed on the node uses OpenSSL earlier than version 1.0. This issue produces an SSL error during any curl connection to the primary server. As a workaround, add --ciphers AES256-SHA to ~/.curlrc so that curl calls always use an appropriate cipher.

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 primary server, 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 primary server: puppet agent -t
  7. Run Puppet on all compilers: puppet agent -t

Converted compilers can slow PuppetDB in multi-region installations

In configurations that rely on high-latency connections between your primary servers and compilers – for example, in multi-region installations – converted compilers running the PuppetDB service might experience significant slowdowns. If your primary server and compilers are distributed among multiple data centers connected by high-latency links or congested network segments, reach out to Support for guidance before converting legacy compilers.

Disaster recovery known issues

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

An unreachable replica runs the primary server out of disk space

If a provisioned replica becomes unreachable, the associated primary server can quickly run out of disk space, causing a complete interruption to PE services. In larger installations, an outage can occur in under an hour. The disk usage issue is caused by the PE-PostgreSQL service on the primary server retaining change logs that the replica hasn't acknowledged.

To avoid an outage, resolve any replica issues immediately, or forget the replica: from your primary server, run puppet infrastructure forget <REPLICA NODE NAME>.

FIPS known issues

These are the known issues with FIPS-enabled PE in this release.

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

FIPS-enabled PE installations don't support extensions or modules that use the standard Ruby Open SSL library, such as hiera-eyaml or the splunk_hec module. As a workaround, you can use a non-FIPS-enabled primary server with FIPS-enabled agents, which limits the issue to situations where only the agent uses the Ruby library.

Errors when using puppet code and puppet db commands on FIPS-compliant platforms

When the pe-client-tools packages are run on FIPS-compliant platforms, puppet code and puppet db commands fail with SSL handshake errors. To use puppet db commands on a FIPS-compliant platforms, 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-compliant platforms, use the Code Manager API. Alternatively, you can use pe-client-tools on a non-FIPS-compliant platform to access a FIPS-enabled primary server.

Configuration and maintenance known issues

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

Restarting or running Puppet on infrastructure nodes can trigger an illegal reflective access operation warning

When restarting PE services or performing agent runs on infrastructure nodes, you might see the warning Illegal reflective access operation ... All illegal access operations will be denied in a future release in the command-line output or logs. These warnings are internal to PE service components, have no impact on their functionality, and can be safely disregarded.

Orchestration services known issues

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

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.

Console and console services known issues

These are the known issues for the console and console services in this release.

Gateway timeout errors in the console

Using facts to filter nodes might produce either a "502 Bad Gateway" or "Gateway Timeout" error instead of the expected results.

Patching known issues

These are the known issues for patching in this release.

Patching fails with excluded yum packages

In the patching task or plan, using yum_params to pass the --exclude flag in order to exclude certain packages can result in task or plan failure if the only packages requiring updates are excluded. As a workaround, use the versionlock command (which requires installing the yum-plugin-versionlock package) to lock the packages you want to exclude at their current version. Alternatively, you can fix a package at a particular version by specifying the version with a package resource for a manifest that applies to the nodes to be patched.

Code management known issues

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

Changing a file type in a control repo produces a checkout conflict error

Changing a file type in a control repository – for example, deleting a file and replacing it with a directory of the same name – generates the error JGitInternalException: Checkout conflict with files accompanied by a stack trace in the Puppet Server log. As a workaround, deploy the control repo with the original file deleted, and then deploy again with the replacement file or directory.

Enabling Code Manager and multithreading in Puppet Server deadlocks JRuby

Setting the new environment_timeout parameter to any non-zero value – including the unlimited default when Code Manager is enabled – interferes with multithreading in Puppet Server and can result in JRuby deadlocking after several hours.

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 main. If the module repository uses a default branch that is not main, an error occurs. To work around this issue, specify the default branch with the ref: key in your Puppetfile.
