Cache is full because no space left - but there is

[Dahacker305]

So I've got 5 drives, all WD 4TB Black 7200RPM, and 1 Samsung 840 Evo 500GB as a cache, now I've got "Fix Common Problems" plugin, and gives me an error that the /var/log is at a 100% usage, so I've checked the diagnostics, and upon further inspection, what's filling up the logs is an error that says,

 

Nov 13 04:40:34 DaServer305 shfs: error: move_object, 2826: No space left on device (28): assign_disk: Personal/iTunes Backup/MobileSync
Nov 13 04:40:34 DaServer305 shfs: cache disk full

it's weird because none of the disks are full, in fact, they all have at least 1TB free, and I've done some googling, but nothing specific to my problem, so here I am asking for help in the forums. I've also attached the diagnostics...

 

Thanks in advance!

The "Personal" share is set to use cache: Prefer.  Which means that it tries to move everything onto the cache drive.  Is this what you want?

Oh wait, I didn't know that it did that, I thought it meant to use it whenever there's space available, then am I supposed to set it to "Yes" instead?

 

Sorry about this stupid question, I'm kind of a beginner
