Meu servidor começou a reiniciar em horários aleatórios sem motivo.
Há muito tempo venho tentando localizar o problema, a princípio pensei que fosse a virtualização/proxmox que ou algum motivo causava as reinicializações.
Mas agora estou começando a suspeitar que meu armazenamento HDD está falhando. O que vocês acham, a unidade de 2 meses já morreu?

O que me deixou preocupado foi o seguinte:
1 Raw_Read_Error_Rate 0x000f 082 064 044 Pre-fail Always - 159956709
Isso está realmente certo? eu li corretamente que há 159956709 erros?

Essas entradas SÃO difíceis de entender, mesmo na GUI smartmontools (que usa smartctl, eu acho). Suas horas de inicialização são 28.583 e seu último teste estendido foi 23.986 horas, então você pode executá-lo novamente se estiver preocupado. Se esses testes forem aprovados e seu log de erros SMART estiver vazio, digo que sua unidade está boa e o problema está em outro lugar. Se você estiver realmente paranóico, poderá inicializar a ferramenta de teste de unidade do fabricante/OEM (link para SeaTools) para usar seu teste; no entanto, eu confiaria no smartctl, já que o OEM tem um incentivo (me chame de paranóico) para dizer que a unidade está OK quando não está (já que eles podem ter que garantir isso)
