The only reason to run fsck after a system crash is to reclaim lost blocks and inodes, FreeBSD-current already has an fsck that runs in the background, so that when you bring the system back up, you do not have to slog through a lengthy manual fsck. I'm not sure when this is planned for the -STABLE branch, but it has to be coming eventually! > I may have this all wrong (someone please correct me if I have) but > soft updates is NOT an equivalent to a journaling file system. True, Soft Updates != Journaling File System. But for most people, it's a functional substitute. -- Christopher Farley www.northernbrewer.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
