deja-dup dispara falhas de E / S de disco no Ubuntu 17.04
Eu tenho um 17.04 recém-instalado (do zero) em um disco totalmente criptografado, com um diretório pessoal criptografado.
Se eu executar o deja-dup para fazer um backup, é garantido que o sistema irá falhar. Se eu citar / var / log / syslog, ele vai dizer algo sobre reduzir as velocidades ata1 para 3.0GB. Infelizmente, não tenho a mensagem exata porque coloca o sistema em tal estado que nada é gravado no disco.
A única opção é forçar o desligamento e reiniciar o sistema, no ponto em que o / var / log / syslog não contém mais as mensagens de velocidade ata1.
Eu verifiquei o status do SSD com o SMART, tudo está OK.
Como posso saber se isso é um problema de deja-dup ou algo mais? E como posso resolver esse problema?
- edit: Eu consegui tirar algumas fotos (já que ele não registra nada no disco)
Ele começa com Failed command: FLUSH CACHE EXT , COMRESET failed (errno=16) , depois o sistema muda para somente leitura e a única saída é o desligamento de força.
- edit: Estes são os dados SMART para o SSD em questão:
