Disco rígido externo fica desconectado enquanto grava arquivos nele

Question

Ubuntu 17.10

Eu tenho um gabinete HW-RAID com duas unidades no RAID 1. A unidade é formatada e criptografada como LUKS / EXT4. O drive funciona perfeitamente quando montado ou desmontado ou quando alguns arquivos pequenos são gravados. (Note que eu tenho várias unidades diferentes de fabricantes diferentes, bem como vários gabinetes diferentes de fabricantes diferentes, todas as combinações de unidade / gabinete produzem esse resultado.)

Agora, quando começo a copiar ( cp -ivpr source destination ) grandes quantidades de dados (20 GB ou mais) para a unidade, acontece o seguinte:

Depois de algum tempo (às vezes 2 minutos, às vezes 20 ou mais)

• o processo cp pára de mostrar a saída no terminal e apenas congela no último arquivo
• cerca de um minuto depois, a unidade fica (provavelmente) desconectada, sinal de áudio para hardware removido
• a unidade desliga completamente, desconectar e reconfigurar não fará nada, também os leds de leitura / gravação estão desligados (mas a energia ainda está ligada)
• gnome-disk-utility ainda mostra a unidade como conectada, mas não como montada, esse estado também não será alterado desconectando e reconfigurando
• o processo cp não reagirá a CTRL+C ou kill ou kill -9 ou kill -f ou qualquer outro kill
• Eu, portanto, desconecto a unidade e reinicio o sistema
• Ao encerrar, os seguintes erros são exibidos e o processo de desligamento para e eu tenho que fazer uma reinicialização a frio

Erros no desligamento

[ 7638.407548] wlp61s0: failed to remove key (1, ff:ff:ff:ff:ff:ff) from hardware (-22)
[ 7638.407938] wlp61s0: failed to remove key (2, ff:ff:ff:ff:ff:ff) from hardware (-22)

Isso é dmesg -T -w logo após a # 3, a unidade desliga completamente
