I have a system running FreeBSD 4.9-RELEASE. It primarily functions as a firewall and router, and is generally pretty lightly loaded (load averages around 0.2). It is a low end system (P200, 64mb RAM, 2 gig hard drive), and is generally stable as a rock. The system has drives setup as follows: / 256M (UFS) /usr 1.2gb (UFS+Softupdates) (/var and /tmp are linked onto /usr/var and /usr/tmp respectively) This morning I noticed that the "/" partition was at 108% utilization, and "df -h" looked like this (approximately): Filesystem Size Used Avail Capacity Mounted on /dev/ad0s1a 252M 256M -8M 108% / Oddly, "du -h -d1 -x" showed only a total of 29Mb used on the partition! The output looked like this: su-2.05b# du -h -d1 -x 68K ./dev 2.0K ./usr 2.7M ./stand 1.3M ./etc 512B ./proc 4.0M ./bin 542K ./boot 2.0K ./mnt 6.4M ./modules 30K ./root 12M ./sbin 4.0K ./tmp 4.0K ./oldvar 29M . When I rebooted the system (without deleting any files), "df -h" showed the following: Filesystem Size Used Avail Capacity Mounted on /dev/ad0s1a 252M 29M 203M 12% / This is good, since the correct amount of free space now shows, and the server is back to running perfectly. Can anyone shed any light as to why this discrepancy happened in the first place? I'd love to know what I can do to avoid ever having to worry about this again!
