Here's what df's output looks like: Following reports of problems with bgfsck during the 5.0-RC series, and prior to the release, I spent some time adding hard disks to machines, resetting without clean shutdowns, and then interrupting background fscks, piles of builds going, etc. When I started, it was fairly problematic, but after Kirk's last batch of buffer fixes, etc, it was pretty much 100% reliable on the boxes I was testing on. However, all those boxes used 40gb drives or smaller. I'll see if I can't dig up some larger drives in the next week or two and try doing that again.
