Question

Puppet agent log shows error could not back up

Answer 1

If agents log errors like "could not back up," nodes are likely attempting to back up files to the wrong hostname, it means that agents can't reach the filebucket server.

On the master, edit /etc/puppetlabs/code/environments/production/manifests/site.pp so that filebucket server attribute points to the correct hostname:

# Define filebucket 'main': 
filebucket { 'main': 
server => '<PUPPET_MASTER_DNS_NAME>', 
path => false, 
}

Changing the filebucket server attribute on the master fixes the error on all agent nodes.
