I can confirm that my hardlinks were lost for many (potentially all? Though to tell) files moved since the update. I used jdupes to identify the duplicate files that were once hard links (took 24 hours due to the size of the share). Good news is, jdupes is reporting exact copies, so no corruption.
I'm happy to provide my logs if it helps.
Question / Request: with the new architecture, is it possible for the mover to only move files, based on criteria in the tuning plugin, up til the threshold being met, and then stop? Or, does it already work like this?
