You have to search for things like XFS and Reiser. Here is one that I did find that's interesting: http://www.freebsd.org/cgi/getmsg.cgi?fetch=15557+19691+/usr/local/www/db/text/2002/freebsd-questions/20021201.freebsd-questions >>> Running fsck in the background might help when 5.0 becomes stable.

I'm not sure if the background fsck capability of FreeBSD 5 is an attempt at an alternate solution to the problem or not. -- Bill Moran Potential Technologies http://www.potentialtech.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
