Uma máquina Debian 6 com o software RAID1 que gerenciamos (mas não tem acesso físico) está emitindo todos os tipos de erros sobre os discos (tanto ATA1 quanto ATA2).
Eu não tenho ideia do que isso poderia ser. Os discos parecem estar bem. Nós não notamos trancamentos ou o que for com os sites que o servidor está servindo.
Eu sei que esta é uma pergunta 'poderia ser qualquer coisa', mas eu realmente espero que alguém possa me ajudar.
Especificações:
Aqui estão alguns dos erros:

O handshake parece sugerir que o controlador está tendo problemas para falar com os drives. Eu suspeito de interferência elétrica, cabos ruins ou possivelmente um controlador ruim. Neste último caso, a placa-mãe precisaria ser substituída. Você só encontrará o culpado por um processo de eliminação, testando cada peça de hardware separadamente.
