Atualizei para o mysql 5.6 a partir do 5.5 e agora meus logs estão repletos de mensagens na inicialização

Encontrei uma solução possível aqui, mas não parece oficial. http://forums.mysql.com/read.php?22,578559,579891#msg-579891

Alguma solução oficial ou correções de 100%?

Eu já resolvi esse problema em: Não é possível abrir a tabela mysql / innodb_index_stats

Essas tabelas são criadas para você quando você instala o MySQL 5.6. No entanto, a atualização do MySQL 5.5 não invoca a criação dessas tabelas. Aqui estão os scripts para criá-los manualmente:

innodb_index_stats

USE mysql;

ALTERNATIVO

Outra solução alternativa seria criar o script a partir de uma instância do MySQL 5.6.

Etapa 01 : Vá para um servidor de banco de dados executando o MySQL 5.6 ou instale o MySQL 5.6 em uma máquina de teste.

Etapa 02 : mysqldump essas 5 tabelas em um arquivo de texto

INNODB_TABLES="innodb_index_stats"
INNODB_TABLES="${INNODB_TABLES} innodb_table_stats"
INNODB_TABLES="${INNODB_TABLES} slave_master_info"
INNODB_TABLES="${INNODB_TABLES} slave_relay_log_info"
INNODB_TABLES="${INNODB_TABLES} slave_worker_info"
mysqldump -uroot mysql ${INNODB_TABLES} > InnoDB_MySQL_Tables.sql

Em seguida, você pode executar InnoDB_MySQL_Tables.sqlem qualquer servidor DB executando o MySQL 5.5 antes de atualizar.

A resposta de Rolando funcionou para mim com algumas adições. Eu tive o mesmo problema, com essas 5 tabelas exibidas via SHOW TABLES, mas SELECT ou outras operações na tabela resultaram na tabela não encontrada.

Para resolver o problema, usando a resposta de Rolando, eu precisava:

• DROP TABLE <tablename> - todas as 5 mesas

• No sistema de arquivos, exclua os arquivos .ibd restantes (os arquivos .frm foram removidos por DROP TABLE)

• Então parei e iniciei a instância do mysqld (não sei se era necessário - fiquei feliz)

• As CREATE TABLEdeclarações fornecidas por Rolando foram executadas sem problemas.
