It's just because the PG hadn't been scrubbed since the error occurred; then you upgraded, it scrubbed, and the error was found. You can deep-scrub all your PGs to check them if you like, but as I've said elsewhere this issue -- while scary! -- shouldn't actually damage any of your user data, so just letting it come up in the normal scrub schedule and running a repair to fix any differences found ought to be fine. -Greg On Friday, July 18, 2014, Randy Smith <rbsmith at adams.edu> wrote: > Greg, > > This error occurred AFTER the upgrade.
