The last time I was using btrfs was around 2014, and I was wondering why my hard drive was always showing 100% utilization even after I moved/deleted a ton-o-stuff.
Turns out at the time, re-balancing still had to be run manually. I'm not sure if that still holds true.
It is still a problem, I just had one of my personal servers hit issues where I couldn't even manually re-balance because the metadata was full. Had to apply weird workarounds to be able to write to that filesystem again...
