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

How long should it take to create the diagnostic log or one of the others? For each log it stops half way and then nothing happens the next hour.

That is too long. You may need to turn off your NAS to generate the log. 

Are you Mac of Windows, Matthew?

Mac

Do you see this file? ~/Library/Application Support/Adobe/Lightroom CC/lrcc_console.log

If so, Zip that and email it to me please!

I dont have any log files on my machine that are similar to that name

I was able to get one to complete: DiagnosticLog.html

Setting your Preference to store Originals on the NAS tells it to store images being actively used by Lightroom CC on the NAS. This includes images yet to be synced to the cloud and images being pulled back down for editing, exporting, sending to Photoshop, etc.  It also includes Albums where you've set the album to Store Album Locally. 

Note that it is not a separate backup of your images. 

I didn't think LRCC used the Originals for editing? 

This is where I've stored a copy of my originals. According to Preferences - > Local Storage.
Nothing in there gets edited, modified or otherwise altered. Just stored.



I have them stored in Date order, and these are the last imports, stored as backups in that location.



All images are stored in the Cloud, from where they are pulled to be worked on, modified or retouched. via Smart Previews. They are then available to all my devices. iPad, iPhone, and Desktop. 
If I need to revert to the original - it is pulled from the Cloud, not local storage.
If I Save the modified image, it is saved to the Cloud as a smart preview, or I can Export it as a new file entirely.
When I import new images, from any of my devices, they are immediately stored up in the Cloud and I can check this by going to the web interface, but they are also stored in the above location at the same time and left there. Becoming effectively a 'backup'

In the Cloud, via lightroom.adobe.com the images and structure are exactly the same as on my Desktop and devices.

Cloud (Web) base


Desktop base



As I mentioned in passing previously when I first imported all my images 43,854 of them, into Lightroom CC I originally had them in LRClassic. I also had them stored as originals on a spare drive. The import from LRClassic simply wouldn't work properly. Big mess.
So I cleaned out LRCC, and reset it to 0. Carefully set up Preferences as you see, with the Originals stored on an Internal drive used only for that purpose.
I then began the Import from the other image file repository. So the images were imported to LRCC, sent to the Cloud - I have a Fibre Optic connection the Internet, and stored locally at the same time in the designated storage location.
The Import and Sync process took about a week to complete. Beware Adobe's pathetic Cloud/internet link.
Even then, there ended up some six I think images that simply would not sync. They just sat there. On them, I gave up. I have no idea what happened to them in the end, because now some two months later everything seems to run smoothly.

Now, if the original posters Local Storage of Original Copies are on a NAS drive, it shouldn't make a blind bit of difference.
Unless there are Spaces somewhere in the Pathname to the folder on the NAS. That shouldn't matter - but sometimes it does.
That's the whole idea of LightroomCC. You can work on your images from anywhere, as everything is stored in the Cloud. That's what I understand anyway? It works for me.
Just out of curiosity - if the OP doesn't have that log file in
 ~/Library/Application Support/Adobe/Lightroom CC/
then there is probably something wrong somewhere else. The file lrcc_console.log should be there. Don't forget the tilde at the start of the path.

My apologies if I'm interrupting - but I find this interesting. because I've seen something somewhere else about NAS problems... 

and ... maybe the OP doesn't have enough Cloud storage? or a fast internet connection. Not that that matters because Adobe's isn't.

Stored... and read when you start editing or zoom to 1:1. And new photos added to there, or removed when deleted.

If there's a local original available, as there is in this case, Lightroom will use the local copy, because it's faster than downloading from the cloud.

Thanks, yes. You reminded me. But the original doesn’t get modified. Just a working copy of it. Which is kept in the catalog.
However. In the OPs case that shouldn’t have any effect on the ability to sync a collection if the originals are stored on a NAS Drive I’d have thought? Unless maybe the NAS is in sleep mode or some other idle state?
???

Yep, it should be "just another storage location" just as if it's an external drive, although they can suffer from LAN connection issues with the amount of data being passed not only up to the cloud but also across the local network to the NAS, and there's an extra layer of NAS software in the mix too. There seems to be a pattern here worth investigating, as sync shouldn't just fail, even if it were to be slower.

Hello, I had the same issue, even with much less pictures (on 2.3). I have since disabled the "store original locally" because Lightroom became completely unuseable: opening 1 picture for editing would take 20 minutes while "syncing" (which stopped progressing).

Sometimes, I managed to get it to resync by pasting whatever edit-settings onto the photos that were not yet synced. It seems that this action re-activated the syncing progress but it was overall very sluggish. I had the impression that it was a bandwidth-related problem, meaning that I think Lightroom could manage to upload to the cloud and to the NAS at the same time.

Having a NAS-based copy of all my pictures is very important to me - As the OP, I'm using a Synology NAS; A feature request I have would be to allow for a Background sync directly between a NAS and the Creative Cloud Library.

I have 60,000 images and after 35,000 stored to the NAS LR has stalled.

I believe the issue is the instruction for LR to use the Originals on the NAS as the primary data source.  LR should just use the cloud originals (and just update the NAS originals as needed).

Rikk, in your testing have you used >40,000 photos?

I have. Still no hiccups

I don't suppose someone could try it on a home network Rikk? I'd guess Adobe's network is optimized to the hilt by a bunch of techie experts, whereas the average home network will likely be slower and hit a few more glitches. I suspect it's worse over WiFi than wired too.
