- moviuro 3y agoIt's a very rare race condition, odds are very low that you were impacted. If you were, you would have noticed (heavy builds with files being moved around where suddenly files are zero).

- keep_reading 3y agobclones were only one way to trigger the corruption. This is not a good way to check. It's also not worth checking for because this bug has existed for many years. Your data probably wasn't affected. None of the massive ZFS storage companies out there ran into it by now either. Your data is fine. Sleep easy.
