You won't find much on it specifically, as it's the file system most modern UNIXes base their file systems on -- i.e., Solaris. It's not journaling. Having said that, I would recommend UFS over ext2fs at *any* time. I've treated my BSD boxes badly, and never lost data. "not losing data", of course, also depends on your application. A lousy database system without rollbacks would hose you on any platform. :) The most I've ever had to do is a "fsck -y" on a bad, bad crash, and that was a couple years ago. IIRC our "softupdates" addition is heading towards being a journaling file system, but the journaling functions won't be ready for a while. ==ml -- Michael Lucas mwlucas@blackhelicopters.org http://www.blackhelicopters.org/~mwlucas/ Big Scary Daemons: http://www.oreillynet.com/pub/q/Big_Scary_Daemons To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
