> those checksums are regularly checked to detect and fix corruption.
I don't believe that's true. They are checked on access, but if left alone, nothing will verify them. From what I've read, you need to setup a cron job that runs scrubbing on some regular schedule.
Yes. Those cron jobs are installed by default by all major vendors that supply/support ZFS.
The setup instructions for ZFS always include the "how to setup regular scrubs" step.
