P: Desktop: Syncing Issues when Originals are stored on a NAS

Here it is, let me know if any more details would be needed:

I think it makes sense to pull this into a new separate post. Make sure you copy all of your observations into the new report and includ as much system information as you can.

Thanks.

One more observation. Synchronization fails for the following case:

- an image exists and has been synchronized

- an image exists with exactly the same name as the previous one but for example a smaller size and in different folder - this fails to synchronize.

I have quite a few such cases and seems that they all fail to sync on the duplicate (just name) of the image. This has not happened before and I have re-synchronized entire library in the past a few times successfully. Was always much faster than now.

I've forwarded this info to Engineering - 

I won't change the status on this thread however as the OP's original issue was marked fixed and this is likely different. 

It has now been synchronizing for 4 hours, with average download speed of 120Mb/s it has downloaded already over 200GB of data and only 4000 photos have been processed. My entire library of 60k images occupies ~500GB so it would download 40% of it and not just 7%.

There is something terribly wrong with the synchronization process.

@Rikk 

A small observation. Seems that the synchronization gets stuck on video files, even smallest ones e.g. 5sec long. When I add a star to such video it gets processed and the synchronization resumes until next video file is reached.

I have now added a star to all my videos and synchronization continues. Let's see for how long... 49k files to go.

@Rikk The issue comes back again in a bit different form. I had to reinstall my PC and all software, including Lightroom. So I have a fresh new install of latest version of the Lightroom Desktop. I've configured it to store all originals on the same NAS folder, mapped to a drive on my PC and trying to synchronize it. After already almost 24 hours the library of ~60k images can't get synchronized, it stops after processing a few hundred images (in the first run it has synchronized over 10k images) but now even after restart it does not synchronize anymore. It starts sunchronizing when I open an album, some of albums get synced completely, some only partially and synchronization stops. When I move to another album it starts synchronizing again. 

Overall, the process is terribly slow, looks like Lightroom is downloading entire photos from the cloud as the app is downloading at 100-150Mb/s, even when there is no progress in synchronization.

The NAS storage and synchronization with the catalog is still far from optimal. It is so much better in the ancient Lightroom Classic 6.0 which I still use for printing... When I move folders in Classic the synchronization takes seconds, not hours.

I have had Lightroom open for the past 9hrs as I can't seem to shut it down. Force quit is not working and I cannot shut my computer properly without shutting down Lightroom first.

I have also attempted to move the local storage, delete the library and change the setting for the Graphics Processor.

The weird thing is, that is working fine on web - I was able to download my last edits and delete images, but the application on the computer doesn't seem to update the changes.

I just keep seeing a loading circle, which freezes sometimes, and then starts again.
