I regularly have checksum errors on three separate drives. Furthermore, when it happens in the last year, it usually happens to all three drives at once. I would suspect the motherboard, but for two years before that it was a single drive that was eventually replaced. In any case, I'm puzzled why I don't see read or write errors too. I'd like help interpreting my smartctl reports, and suggestions on how to pin down the guilty hardware.
The system is nearly three years old. From the start, it had two Seagate Desktop drives and one Hitachi Deskstar; all 4TB in raidz1. For the first two years one of the Seagate drives kept failing checksum tests. I swapped SATA cables and power cables, disabled power-down and acoustic management, and tried everything else I could think of. Nothing made a difference. Eventually Seagate simply replaced it.
Since that replacement last February, all three drives regularly fail checksum tests. Of the 19 times that has happened, over half the time all three drives faulted together. There has never been data loss. I've always been able to run (zpool clear).
There is also a WD 6TB drive and a 60GB SSD that were added just two months ago.
FYI, I have smartctl running long tests daily on the three original drives and don't recall every being notified of a problem. I just added a long test task for the new drive too.
Below you'll find my system summary, today's daily report, and smartctl results. Let me know if there is anything else I can provide.
Thank you,
Scott
