Thanks, I’ll try some of those things out and see if a second scrub says the same.
That being said I have pretty good backups
Out of curiosity, what do you do for backups? The initial cost of 3x12TB drives was enough to make me not want to spend a bunch more money on backup stuff at the time, but now that I’m seeing errors I’m willing to spend a bit of money again and should look into my options.
