It does make directory operations run as async speed, with no corruption problems in the event of a crash. Theoretically, a softupdates-mounted filesystem can be mounted 'dirty' and cleaned in the background, but I believe there are some problems with that that haven't been worked out yet. fsck time seems to be proportional to the number of files (so your CVS repo will really take along time :) On my machine, fsck'ing a 9-gig drive takes about 5 minutes. fsck'ing a 60-gig volume takes about 10 minutes, but there aren't very many files. -- Dan Nelson dnelson@emsphone.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
