I currently have my docker.img file set to 25GB however overnight up until right now I had just been getting notices of 70-75% utilization on and off constantly. 

 

My container sizes are only 13.2GB and then if wirtable adds onto that too, then my total size is 14.5GB.

 

However if I look at my docker volume info I see it's using 19.5GB. 

I'm not sure where the discrepancy is coming from or how to fix it. 

 

Total devices 1 FS bytes used 14.50GiB
devid    1 size 25.00GiB used 19.52GiB path /dev/loop2

Total to scrub:   15.72GiB

Did you figure this out?  I have the exact same issue starting on May 21.  Always between 3 and 5 am roughly.

Not really, I assumed there was some new containers using up more in the image, I'm not sure what's new, but when containers update (if you ahve it scheduled then) it may be why it's filling up more around those times.

 

I just stopped docker, added 5GB to my img file and I haven't had a warning since!

I considered doing that also but I would prefer to change the warning setpoint.
