8 discos em RAID6 no hardware HP Proliant DL180 G5
Meu kern.log me diz que eu tenho um erro no sdb, como mostrado abaixo:

O comando arcconf está me informando que todos os estados do disco estão on-line & Listras com falha: sim
Como posso identificar qual disco é ruim fora da matriz RAID6 de 8 discos?

A menos que eu esteja enganado, esses erros estão dizendo que você tem erros que não foram corrigidos pelo controlador RAID. O controlador RAID deve estar escondendo erros como esse de você. Eu não acho que você tenha uma falha simples no disco. Eu acho que você tem algo mais sério acontecendo.
Assumindo que o volume "boot" em sua configuração de raid é reconhecido como sda e "data" como sdb, seu sistema lhe diz o seguinte:
[2740390.344436] sd 4:0:1:0: [sdb] Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE
O subsistema scsi emitiu um comando sem erro para o driver de nível baixo (para sua placa adaptec) e a placa respondeu com um erro (DRIVE_SENSE está configurado).
[2740390.344439] sd 4:0:1:0: [sdb] Sense Key : Hardware Error [current]
Este é o tipo de erro (veja informações do driver scsi ) .
[2740390.344442] sd 4:0:1:0: [sdb] Add. Sense: Internal target failure
Esta é uma informação adicional que o driver reporta enquanto esta informação, até onde eu sei, significa "nenhuma informação específica" / "não tem idéia do que deu errado".
[2740390.344454] end_request: I/O error, dev sdb, sector 870177792
O erro atingiu a camada de bloco.
Como afirmado em outra resposta: isso não é uma falha de disco único, isso é uma falha de todo o ataque. Você deve verificar seus dados cuidadosamente e considerar a substituição do subsistema de raids ou pelo menos do controlador.
E você deve sempre (!) habilitar "Verificação de consistência de plano de fundo" / "Verificação passiva" / "Verificar" em seus controladores de raid para localizar corrupção silenciosa que pode matar seu ataque no caso de uma reconstrução.
Você viu algum erro no sistema de arquivos? É / dev / sdb particionado / montado?
Isso parecerá engraçado, mas você olhou na frente do servidor para ver qual unidade tinha um LED de erro aceso? (supondo que as unidades tenham LEDs)
Além disso, você pode instalar o software gerenciador de armazenamento: link
É possível obter as informações por meio do smartctl (CLI) ou do CLI da Adaptec (como mencionado acima)
Se você puder reinicializar o servidor, faça-o no SmartStart DVD. Se eu me lembro, você pode acessar a ACU a partir daí para ter uma visualização gráfica dos volumes RAID.
