FreeNAS-11.3-U2.1
In the past week, Freenas ran a scheduled scrub on the pool and then reported errors. I deleted the file with errors because I didn't need it an ran a manual scrub on the pool. At the end of the scrub, another file is showing errors.
This has happened twice in under a week, and three times in the past 6 months or so. What is the cause of this and what do I need to do to correct it.
