After a Disaster Recovery failover in Puppet Enterprise, PuppetDB is unresponsive

After using Disaster Recovery to failover to a new Puppet Server, PuppetDB is unresponsive to queries.

Version and installation information

PE version: All supported versions
Installation type: using Disaster Recovery

Solution

During a Disaster Recovery failover, when initial data synchronization takes place, PuppetDB goes into maintenance mode. During that time, PuppetDB is unresponsive to queries. You can use an API call to check whether PuppetDB is in maintenance mode.

Run this from any node in your installation:

curl -k https://$(puppet config print server):8081/status/v1/services/puppetdb-status | python -m json.tool

If PuppetDB is not in maintenance mode and remains unresponsive, open a ticket with Support and attach a PuppetDB log, located on your PuppedDB node, usually the primary server, in /var/log/puppetlabs/puppetdb/puppetdb.log. Make sure that you remove any sensitive information before sending it to us.
