O nó Galera não será iniciado após a recuperação

Question

Eu tenho um "Cluster" Galera com um nó de trabalho. Eu adicionei um segundo nó e iniciei a sincronização via rsync. A transferência do Estado foi bem-sucedida, mas ao iniciar o banco de dados, ele me diz que o innodb deve ser desativado. Mas, tanto quanto eu entendo Galera isso deve ser exatamente os mesmos dados, em seguida, no node1.

Aqui está a saída do registro:

O que eu também vejo: em ambos os servidores, não existe o arquivo ./tde/SOURCES.idb.

    

Answer 1

Desculpe, mas estou confuso. você tem 3 nós que dizem node-1, node-2, node-3.

De acordo com suas informações, o node-1 está funcionando e você está tentando adicionar o node-2. (O log que você compartilhou é para o nó 1? O node-1 também está enfrentando problemas?)

Além disso, qual método de SST você usou para xfer.

Se possível, você também pode compartilhar o arquivo de log completo, pois isso é confuso e não é esperado que aconteça.

Feb 19 17:05:56 node1.example.com mysqld [38851]: 2017-02-19 17:05:56 140274267547840 [ERRO] InnoDB: Tentativa de abrir um tablespace aberto anteriormente. Espaço de tabela anterior mysql / innodb_index_stats usa o ID de espaço: 2 em filepath: ./mysql/innodb_index_stats.ibd. Não é possível abrir o espaço de tabela tde / SOURCES, que usa o ID do espaço: 2 no caminho do arquivo: ./tde/SOURCES.ibd

Dado que space-id foi alocado para alguma outra tabela que foi aberta pelo MySQL e postar SST, o mesmo space-id é alocado para alguma outra tabela.

    

Answer 2

Você deve estar mais claro em sua pergunta. De acordo com a sua pergunta aqui , mas não mencionado acima, você tem 1 nó que aparece estar trabalhando e estão no processo de adicionar um segundo nó. Você está recebendo este erro no segundo nó.

Isso pulou em cima de mim quando passei pela primeira vez pelo seu log de erros e, com o erro, parece que você está começando com um banco de dados corrompido no nó 2.

Feb 19 17:05:56 node2.example.com mysqld[38851]: 2017-02-19 17:05:56 140274267547840 [Note] InnoDB: Database was not shutdown normally!

Todas as suas tabelas são InnoDB com chaves primárias?

Espero que esta seja uma configuração de teste para você e não para produção. Como tal, sugiro limpar o diretório de dados no nó 2 e tentar iniciar o serviço novamente. Isso garantirá um início limpo quando o MySQL iniciar novamente e é o que o Xtrabackup faz para o SST. Não me lembro de o rsync ter corrompido todo o diretório de dados, portanto, isso deve eliminar qualquer problema, pois o rsync não remove nada que possa estar causando problemas.

Você pode compartilhar suas configurações para os nós 1 e 2? Pelo menos as configurações relacionadas ao wsrep_ *.
