Por que meu WDC WD20EARX-00PASB0 em um RAID não para de girar?

5

Meus discos estão girando há meses. Começou com o Ubuntu 11.10 e continua com o 12.04. Eu não consigo descobrir como pará-lo. Eu olhei para várias pessoas sugestões on-line sobre tempos de commit ext4, noatime, etc. Eu fiz o que eles disseram, mas ainda sem sorte. É agora como a tortura da água chinesa ... Eu ouço aqueles discos que estão constantemente começando a me deixar louco.

jdb2 / dm-1-8 e jbd2 / db-0-8 são tipicamente os principais usuários de IO. No entanto, eu fechei quase tudo, "echo 1 > / proc / sys / vm / block_dump", e assisti dmesg. jbd2 / dm-1 e jdb2 / dm-0 são liberados de forma confiável a cada 60 segundos, mas o disco rígido continua girando nesse intervalo. dm-1 é montado em / home e dm-0 é montado como /.

Minha configuração é um pouco complicada:

Eu tenho um SSD onde o root mora e, em seguida, dois drives regulares espelhados com o software RAID, onde outras partições LVM vivem.

Além disso, existem partições LVM. Então, / home é criptografado com ecryptfs.

Aqui está a saída do pvdisplay:

Com base nos números de modelo (WDC WD20EARX-00PASB0), os dois discos RAID são drives "verdes", conhecidos por estacionar e desimpedir constantemente os cabeçotes da unidade e não são recomendados para uso em aplicativos RAID.

Dê uma olhada na saída do smartctl ou no "Disk Utility" gráfico para ver as estatísticas SMART dessas unidades. Eles são propensos a contagens de ciclos de carga / descarga muito altas, que resultam de seus recursos de economia de energia.

A WD fornece um utilitário chamado "WDIDLE":

que lhe permitirá alterar essa propriedade e reduzir ou desativar o estacionamento automático da cabeça para ajudá-lo a recuperar sua sanidade mental.

Infelizmente, como mencionado acima, essas unidades não são recomendadas para uso em aplicativos RAID, portanto, a melhor abordagem seria substituí-las por unidades adequadas e evitá-las no futuro.

Procure o Google "Green Drive Raid" e você encontrará muitas pessoas com problemas com essas unidades.
