New: Provisioning a replica node that’s connected to a compile master causes Puppet runs to fail

If you try to provision a replica node that’s connected to a compile master, rather than a primary master, it can cause an error:

Failure during provision command during the puppet agent run on replica 2:
Failed to generate additional resources using 'eval_generate': Error 500 on SERVER: Server Error: Not authorized to call search on /file_metadata/pe_modules with {:rest=>"pe_modules", :links=>"manage", :recurse=>true, :source_permissions=>"ignore", :checksum_type=>"md5"}
Source: /Stage[main]/Puppet_enterprise::Profile::Primary_master_replica/File[/opt/puppetlabs/server/share/installer/modules]File: /opt/puppetlabs/puppet/modules/puppet_enterprise/manifests/profile/primary_master_replica.ppLine: 64

As a workaround, on the replica you want to provision, edit /etc/puppetlabs/puppet.conf so that the server and server_list settings use a primary master, rather than a compile master.

Executing enable command immediately after provision can cause error

If you have scripted or automated the process to set up a replica, the enable command can sometimes fail with the error, ‘ERROR [p.p.puppet] Received a PCP error message due to message 7f7ed934-d2ed-4d64-8b5c-e2cb48cb2227 (blocking request for ‘status query’)’.

To resolve the issue, run puppet agent -t on both the master and replica nodes, then try the enable command again. There is a fix planned for this issue in a future release.

Running puppet infrastructure configure fails on promoted replica

The /etc/puppetlabs/enterprise directory contains configuration files used during the installation and upgrade of Puppet Enterprise. These files are not automatically copied to a replica; this poses no issue during normal operation, but may cause problems if you need to upgrade Puppet Enterprise on the replica after it is promoted.

To avoid potential issues:

  1. Back up the /etc/puppetlabs/enterprise directory of the primary master.
  2. When you promote a replica, copy the backup into place.

This directory will be automatically copied to the replica in a future release of Puppet Enterprise.

After HA enablement, both server and server_list are set

When the puppet agent configuration file contains settings for both server and server_list, a warning is printed. This can occur after enabling a replica in a high availability Puppet Enterprise configuration. The warning can be ignored, and will be downgraded in a future release.

If you want to hide the warning, remove the server setting from the agent configuration, leaving only server_list.

Running enable starts an orchestrator run that fails

When provisioning and enabling a replica, the orchestrator is used to run Puppet on different groups of nodes. If a groups of nodes is empty, the tool prints the text, “nothing to do” and the job is marked as failed in the output of puppet job show. This is expected, and does not indicate a problem.

RBAC displays permission denied error

On a primary master replica, error messages similar to this may appear in the console services log file:

2016-11-11 17:34:22,824 [pool-4-thread-2] ERROR [p.c.class-updater] Encountered an unexpected exception while trying to synchronize classes from the Puppet Master:
org.postgresql.util.PSQLException: ERROR: permission denied for relation environment_classes

These errors may be ignored.

Latency over WAN can cause failure

If the master and replica communicate over a slow, high latency, or lossy connection, the provision and enable commands can fail. If this happens, try re-running the command that failed.
