请教负的空间问题,本人系统为FreeBSD4.7

rryyaann

删除了/var/spool/mqueue下的垃圾文件后,用df命令看/var下还是负的空间
ipf# df
Filesystem 1K-blocks Used Avail Capacity Mounted on
/dev/ad0s1a 2032623 32368 1837646 2% /
/dev/ad0s1f 1016303 10 934989 0% /home
/dev/ad0s1g 2032623 482881 1387133 26% /usr
/dev/ad0s1h 31343383 4295349 24540564 15% /usr/nc-home
/dev/ad0s1e 2032623 2032233 -162219 109% /var
procfs 4 4 0 100% /proc


然后我在运行fsck /dev/ad0s1e的时候出现以下信息.

** /dev/ad0s1e (NO WRITE)

这是FreeBSD为了防止因为磁盘空间用光而发生系统崩溃的一种保护措施，你只要删除一些文件就可以了。
