I am using the expandable cache. The size is set for 300GB.
I use the drive for torrents so I am seeding and saving to the clouddrive.
During these instances, I'd see the local cache full at 300GB, then if I start downloading a file, the to upload grows so the total cache might get up to 320GB and then work its way back down to 300GB once the upload has completed.
What I have experienced is when these transactions are going on, at some point the local cache resets and only has the upload data remaining and maybe a couple of gigs, probably the data that has started to upload being cached back locally?
I haven't caught it right as it happened but that last time, yesterday I noticed it shortly after all of this happened because the local cache was very low, like 1GB and then slow grew back, currently I'm still not hitting the max 300GB, I'm sitting at 218GB local.
