I thought that having background_fsck="NO" in your rc.conf would make the partition get mounted even though it is unclean, and no fsck's would happen (I use this 'feature' right now, since doing bgfsck on a 2TB partition takes about 2 hours just to make the snapshot, which means filesystem activity is suspended for that time). If it was set to "YES", and bgfsck exited abnormally, I don't think it will get mounted automatically, so he would have had to manually mount it, correct? Mikhail, do any of those scenario's sound like a match?
