In worse cases it required manual attention :) UFS is used and improved 
over 20 years, it's SIMPLE and practically bug-free now, except snapshots.

I think it could be improved a bit more to support multiterabyte disks 
better. Like more blocks allowed per cylgroup and few other changes that 
will result in no more than 1000 cylgroups on that devices. This will 
improve fsck times a lot.

Still it's well usable on 2TB disks.
