I/O Throttled "low on disk space AFTER I cleared cache

[ccooluke]

I have a 500GB SSD dedicated to stablebit cloud drive. The cloud drive is a google drive. I have the cache set at 470GB. I'll copy over say 350GB(ish) at a time. once it finished uploading, if I clear cache and stablebit tells me there's nothing in "local" I go to transfer another 350GB. I get an I/O error in stablebit, the transfer between hard drives slows or stops because 350+350=700 which is more than the cache of 470. but I cleared the cache so the first 350 should be gone, and I should have that space back for the next set of 350GBs. makes sense?

But I end up having to "detach drive" and then reattach it every single time I want to do transfers like this. I feel like I am doing something wrong, or am missing a setting or something. I shouldn't have to detach the drive every time like this. it makes no sense. any suggestions would be amazing, thank you.

It sounds like you may have data in the "to upload" cache still, and that it doesn't have enough room left. 

Also, I would recommend 50GB of free space for the buffer.

And what cache type are you using?

Right now I have the cache as 50GBs expandable. I uploaded 155GBs today. It has finished uploading for hour now. However Ot still shows that I have 155GBs on my Local hard drive, I never get that space back. 
now I did some more digging, and I found if I reformat the drive to ReFS instead of NTFS, I can upload and get back that local space instantly. I did here from a few people to not use ReFS, but if you suggest to use it, then I think that’s really my only solution.

Was the CloudDrive disk formatted as ReFS?

No... I mentioned that I reformatted it to ReFS from NTFS... and that all my problems are in NTFS

Ah, sorry, I flipped that in my head, I think.  

And that difference may be the way that NTFS and ReFS allocate the data on the drive.
