Primeira vez tentando tirar cara e coroa disso. Eu só me pergunto se a unidade é ruim neste servidor? Apenas as coisas parecem tão lentas quando compilando e executando tarefas simples (coisas pendem). Como a média de carga fica tão alta (8.00) e a% WA é muito alta também, às vezes, para nada rodando no topo.

Eu simplesmente não entendi. Eu estou compilando agora, mas nada está aparecendo no topo, mas estou ficando no máximo em WA% e o processo de compilação é como ficar sentado aqui sem fazer nada e, depois de um tempo, pegar de novo. / confused

Parece que pode ser um problema de hardware, mas de acordo com a saída SMART, esse disco parece estar bem, pelo menos. Você pode tentar usar o iotop para ver quais processos estão causando todo o pedido de veiculação. Então, para responder à pergunta: não, não parece uma falha no disco rígido, dada a informação atual.
