One day I was surprised to find my home-assistant zvol was corrupted. But I was even more surprised; no single drive contains errors. And double scrub helps temporally. After a few hours, the error reappears. Home-assistant runs just fine, without any visible data corruption. HA generates ~200MB of sensor data in sqlite daily. Does not look a lot. The disks are brand new, but another part is repurposed old PC. Any idea what happened and how to fix it? My idea is that one of the devices corrupts data, but which one?
