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

I'm experiencing the same issue where Lightroom CC is essentially unusable while configured to store all originals on my NAS and the NAS is mounted. This thread made me realise that I can unmount the drive and have everything except the backup work.

Important info...

Assets in library: 70k
Assets not synced: 54.5k (78%)
Library size: 518GB
LRCC version: 2.4.1
OS version: macOS 10.14.5
NAS: Synology DS1511+
Mount type: SMB

When my NAS is mounted, there's an interesting behaviour where the first time I launch LRCC I can click on the cloud icon in the top right and see the library size and that it's "Syncing n photos", but if I dismiss that little popup and click the cloud icon again I cannot see the library size or the number of photos remaining to be synced.

The same thing happens if I open Preferences to view the library size shown in the 'Account' tab: it works the first time but the next time I open it there's no sizes listed against 'Backed Up' and 'Available Cloud Storage'.

There are a few others things that don't work while my NAS is mounted:

• In the Local Storage preferences menu, 'Required Space' says 0 bytes, and 'Photo Cache' says 0.00 MB
  
• Navigating between albums or even trying to filter my library (e.g. to see photos where Sync status = 'Syncing') or doesn't work and the loading spinner never disappears
  
• Generating a diagnostic log never finishes (it hangs at approx. 50% progress)

As soon as I unmount my NAS and relaunch LRCC everything (except having those 54k photos sync...) works as expected. I've been impressed with everything else after switching from LR Classic, so I'm really hoping there's someone from Adobe looking into this unfortunate trend.

How is the external disk connected? If it's not network storage, that could be a different issue.

I have the same issue with MacOS 10.14.6 and Lightroom 2.4. Upload is stalled. My photos are on an external disk.

P.S. I also have problems logging into this forum using the Brave browser because of nasty third party cookies used for tracking purposes.

Same issues with about 11,000 images and 330 GB (all RAW.) Lightroom is unusable because neither images nor previews load. It also freezes all the time trying to move newly downloaded images. Single albums with anything from a dozen to a few hundred images also freeze, so I'm not sure the number of images would play a big role.

Funnily, when I unmount the network device before starting LR because then Lightroom relies on the caches or downloads it from the cloud which apparently is much faster than reading it from the NAS, so everything works flawless....

I want the originals on the NAS for backup purposes so I currently, as a "workaround" just mount the NAS folder for new images and then unmount it afterwards... It's a bit stupid but well

Edit: BTW I tried 2.4 too, so the problem does not appear to be solved with the new update.

Hello, The problem is exactly the same with small databases, I have one set up with <5000 pictures and 200 GB.

I would bet that it is a problem of ressource/bandwidth allocation when uploading and copying. I experience similar "freezes" for example when I copy files to the NAS and try to sync LR CC. Very often LR would "lose track" of the number of pictures to be synced and just stay unresponsive.

I was facing the same problem as described in this thread, deleting my online catalog and re-synchronizing it from scratch fixed the issue, only 170 images were not synchronized and I have to fix them manually. Since then all new photos or edits are synchronizing without any issue (although speed is far from my expectations or LR classic).

Thanks. Adobe's having a little trouble reproducing it, but I suspect they need to test with a larger number of photos. Mine seems to grind to a halt at about 22k out of 100kish. I'm wondering if anyone sees it with smaller volumes (e.g. 20k or less)

What's the theory?
