UFS2 is here since IMHO year 2005. Now the only problem is fsck time. actually IMHO fsck can be improved a lot but someone must have time and will to do this. if parallelism would be exploited on gstripe type(*) volumes then it should take less than 30 minutes no matter how large the volume is. Anyway - even with UFS which is the most fault-resilent filesystem i know - i would not recommend creating gstripe type volumes taking too many disks for the reason i already explained. For now softupdates+journal is fine, you actually have to do full fsck now and then, but at spare time. *) gstripe type means gstripe, gstripe+gmirror, graid5, graid5+gstripe, hardware matrix controller with any type of RAID configuration.
