O Smart está relatando o seguinte erro todos os dias: um dos meus SSDs do servidor do data center:
This message was generated by the smartd daemon running on:

The following warning/error was logged by the smartd daemon:
Device: /dev/sda [SAT], 1 Currently unreadable (pending) sectors
Device info:
INTEL SSDSC2BB480G7, S/N:PHDV701605XT480BGN, WWN:5-5cd2e4-14d60bdf9, FW:N2010101, 480 GB
For details see host's SYSLOG.
You can also use the smartctl utility for further investigation.
The original message about this issue was sent at Tue Feb 6 18:43:41 2018 EST
Another message will be sent in 24 hours if the problem persists.
Syslog, não mostra informações adicionais.
Li em outro lugar que preciso executar um teste inteligente estendido e, em seguida, gravar no setor especificado nos resultados do teste para forçar a unidade a marcá-lo como um setor defeituoso e realocar.
Eu fiz um longo teste:
sudo smartctl -t long /dev/sda1
Mas a saída do sudo smartctl -a / dev / sda1 diz que o teste foi concluído sem erros?

Existe realmente um problema? Em caso afirmativo, como diagnosticar corretamente?
Apenas 1 setor pendente não é um problema para uma unidade. Apenas ignore-o até aumentar significativamente.
Embora você possa tentar corrigi-lo usando as seguintes instruções (dados de backup primeiro!): link
Você também pode comparar sua unidade S.M.A.R.T. reportar com outras pessoas em este repositório de S.M.A.R.T. relatórios .
A grande questão é saber se esse setor tem dados de que você gosta, tente ler seus arquivos de dados e ver se algo está faltando.
De qualquer forma, para evitar que essa mensagem de erro seja repetida, você precisará sobregravar os dados para que a unidade ignore isso. Cortar o bloco se não tiver outro uso também deve funcionar. Você pode tentar fazer um fstrim no sistema de arquivos para limpar isso.
O teste longo SMART faz um teste aleatório da mídia e não é um teste completo, portanto, pode ser bem-sucedido mesmo se houver um erro e, especialmente, se for um erro recuperável do tipo, pois o fabricante não deseja que um único erro pendente fará com que você RMA a unidade.
