И периодически со всеми тремя из пула в лог валятся ошибки:

У меня этих дисков было с запасом и после первых сообщений, я "сбойный" диск заменил новым из упаковки. smartctl для него все показатели выдал сразу такие-же как для остальных. Т.е. все строки с "Pre-fail" статусом были.
А в итоговых логах смарта пишет, что ошибок не обнаружено. zpool тоже выдаёт статус без ошибок.
В чём может быть дело?
Кабеля у дисков этих трёх, разные. В порты на мат. плате они воткнуты: 2 диска в группу портов SATA, один в группу портов SATA-2.
Диски из пула размечены в GPT, с 4k выравниванием.
И с двумя зеркальными дисками никаких ошибок не выдаёт.
