So, apparently we fill up even more space than anticipated. It's not on every run so we might just be able to turn it down a little bit...

I haven't looked yet but I suspect we're just running for a set period of time and the smithis are so much faster than the HDD-based nodes that they manage to entirely fill the drives. So the cheap solution is to just turn that timer down everywhere, or maybe we can configure differently based on machine type...

ffsb (config is at qa/workunits/suites/random_write.32.ffsb) only use about 13G space, no matter how long it runs. I checked the log, OSD is on top of btrfs. I think it's caused by btrfs' long-standing premature ENOSPC issue.
