Negative value??? FreeBSD giving me a few extra megs for > free? Waw :) By default, 8% of all filesystems are reserved, to help with the allocation of contiguous blocks for large files.

When it hits 108%, even root will get disk full messages. -- Dan Nelson dnelson@allantgroup.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
