ZFS Reported Unhealthy, no Errors

My drives reported checksum errors. But ZFS says there no errors. But is reporting as unhealthy. 1 drive is reporting 3 checksum errors and multiple others are reporting 1.

How can I fix the checksum errors?

I am running smart extended test will attempt scrub a second time after that. It from my research could be a failing lsi card.

I had the same, it was a memory issue.
I don’t know how good stress-ng detects memory issues, if you can run Y-Cruncher VT3/VST or TM5
