Lightroom CC: [BUG] - Available space

Hi!
 
I'm using Lightroom CC and when I go into Preferences > Local Storage I get this:



It is set to use 25% of remaining disk space. Also, it show that available space is "98.33GB" if I understand this correctly.

However, the available disk space on my drive is 7.37GB. So I would like Lightroom to reduce the Photo cache.

Why does Lightroom think that I have almost 100GB available when I only have a bit over 7GB?

From this screenshot I can't see what the available space on your HD really is, but Lightroom does seem to think it's about 98 GB. So why don't you simply lower the 25% setting to fee up space?

No... I shouldn’t have to lower the space to 1% or something to make up for a bug :)

It might not be a bug. MacOS X has processes that can sometimes take up temporary space (for example Time Machine makes a local backup when your Time Machine disk is not available, but will give up that space when needed for something else), so perhaps Lightroom is including that in its calculation.

And if you want to free up space now, the only way of doing that is taking action yourself. If it is a bug it needs to be corrected, but it the meantime you may want to help yourself by lowering that percentage...

You are talking about "Purgeable disk space" in macOS. I have 117.9MB of Purgeable disk space, so it is not that.

Perhaps you need to empty your trash?

It is empty. And it wouldn’t make any difference. Thanks for the suggestion.

Where did you check to find out that your available disk space is 7.37GB?

In Finder. I also checked Disk Utility.

I cleaned up some stuff on my disk and now I have 13GB available on my disk. Lightroom thinks I have 104GB. Makes no sense at all...

You've already contacted Adobe. This is the forum to report bugs and request features.

BTW, I would lower that cache right now if I were you. Having only about 10 GB free space is very limited and could be a problem already. Your entire computer may run slower than it has to because there is too little space for temporary storage.

Oh ok. Let’s hope someone from Adobe sees this and takes the appropriate measures to rectify this.

Thank you for your help I really appreciate it!

Hi Linus,

Thanks for your post.

So, as Johan mentioned, you have, indeed, contacted Adobe. I'm one of those guys! We are discussing this issue and will log a bug if it's not already been done.

An update here and some more issues.

Rick has contacted me and they seem to be working on a solution to this. I hope they can find a fix soon :)


On another note... I tried to lower the "Photo Cache" size to 10% instead, so now my settings look like this:



Shouldn't this make the "Originals" folder smaller now? Because nothing happens and I still have 95GB of photos on my drive (yes, I have restarted Lightroom CC after making the change).

Am I misunderstanding this feature?

Yes, it should make it smaller (the 9.92 GB in the preferences), but this may be part of the problem.

It seems to be doing something actually. Now the Lightroom "originals" folder is only 87GB. So in a few weeks it may be at the correct cache size :D

There is supposed to be some intelligence built-in to the space management process. Although I don't have any specifics on what checks are done, I can easily imagine for example that deleting the imported files from the local system, as soon at they have been synced and backed up, might be delayed for a while depending on actual free space on the drive and frequency of access. I've just checked and, although I do not have the "Store a copy locally" enabled, some imports I did back in early February are still in the local cache.....and furthermore, LRCC knows it. So if I access those files frequently (which I would more likely do in the month or two after import) I would expect LRCC to use the local copy in preference to downloading the original from the cloud whenever I open the file in Detail view. But as my use of those files becomes less and less frequent, they'd more likely become eligible for deletion.

I have no problem with that behaviour provided it does take actual free space availability into consideration. I have plenty of free space on the drive in question, so can't really test that.
