Leme: não é possível atualizar políticas

Question

Quando tento atualizar políticas em um agente, esse erro aparece:

Failed to canonicalise filename '/var/rudder/share/0f546498-93eb-41fc-835e-111045a7971f/rules/cfengine-community/rudder_promises_generated' (realpath: No such file or directory)

Examinando os logs da conexão usando a depuração do servidor ( rudder server debug 10.222.111.38 ), descobri que o diretório que o Rudder cria para o agente é /var/rudder/share/6149530e-db36-49d3-81da-ed3c450ce692 not /var/rudder/share/0f546498-93eb-41fc-835e-111045a7971f e essa é a causa do erro. Aqui estão os logs:

Então, o que poderia estar causando esse comportamento?

Estou usando o Rudder 4.1 no Ubuntu 12.04.

Answer 1

Parece que o id do nó foi alterado (era 6149530e-db36-49d3-81da-ed3c450ce692 e agora é 0f546498-93eb-41fc-835e-111045a7971f ).

Você reinstalou o nó ou executou uma reinicialização do leme (o id do nó está localizado no arquivo /opt/rudder/etc/uuid.hive).

Duas maneiras de corrigir isso:

O mais fácil, Remova o Nó do Leme, execute rudder agent inventory no Nó e espere que o novo Nó apareça na página "Aceitar Novos Nós" e aceite-o. Você precisa fazer isso porque, para o leme, é um nó diferente e o antigo não existe mais.

A outra maneira é alterar o valor do arquivo uuid.hive para o antigo (assim, 6149530e-db36-49d3-81da-ed3c450ce692 ), mas isso pode não ser suficiente, porque a chave do agente pode ter alteração. Você não deve fazer isso, pensou, a menos que você alterou o conteúdo uuid.hive e é isso que causou o erro que você está vendo agora.
