How to replicate a zpool write error that happens in TrueNAS SCALE in Windows?

[duncandoo]

I've described the error that is occurring here. After much investigation the motherboard manufacturer agreed to replace the board becuase the error seems linked to a specific SATA port on the board. However, the replacement has exactly the same error. They are now saying they cannot investigate further unless I can replicate the error on Windows.

In summary, I create a RAID-Z2 pool of 8 4TB HDDs. The drives sit there quite happily, and pass SMART tests. However, as soon as any load is put on the pool, like loading data on to it, a number of write errors appear on /dev/sdb, which is the drive connected to SATA3_7 port. The drive is marked as faulted, the pool degraded. The SMART attribute UDMA_CRC_Error_Count has increased for that particular drive. I have tried different wires, different power connectors, with and without the backplane, different drives etc. The common point to all these errors is that it is /dev/sdb and it is the drive connected to SATA3_7.

So my question now is, how do I test the same hardware running windows to replicate a zpool write error and UDMA_CRC_Error_Count increases? Or what is the closest I can get in Windows to generating some evidence.

If anyone has any experiences of trying to do this, I'd be most grateful for advice.

SInce (I assume) this is a dedicated installation strictly for diagnostic purposes, you could try installing ZFS on Windows. As far as I know there is a work in progress port. Website is down. I just asked the project contacts on twitter and will report back when I get any news.

EDIT: Server is down, they are working on it. The URL is OpenZFSonWindows
