after upgrading from Lightroom 3.2.1 to 3.3, I get an error stating that my storage location for originals, located on a NAS drive, is full. In reality I have plenty of space on the shared folder. When rolling back to 3.2.1 the issue is resolved. My os i Catalina 10.15.5 the NAS is Synology. However I believe this issue is related to Lightroom
Well, if it helps you I have exactly the same issue and came here looking for someone else with it. I have exactly the same versions and NAS as you as well so I'm not sure that helps isolate the bug down that much yet 🙂 But being as LR is the only thing that's changed, I'd agree it's something in LR's logic that broke.
