Well, my thoughts would be in either /tmp or /var will give you the most trouble. It's not a good idea to leave these on the root filesystem. / should be read-only for all intents and purposes. The more writing you do to /, the more chance you have to corrupt it. > > below is df output: > > Filesystem 1K-blocks Used Avail Capacity Mounted on > /dev/da0s1a 297663 255876 17974 93% / > /dev/da1s1e 297663 173693 100157 63% /usr/local > /dev/ad0s1f 992239 668380 244480 73% /usr/src > /dev/ad0s1e 2980238 2209800 532019 81% /backup > /dev/ad0s1g 4037030 2587663 1126405 70% /backup2 > /dev/vinum/vinum0 7000492 6230498 209955 97% /mnt > /dev/da2e 68798704 7827914 55466894 12% /ftp > procfs 4 4 0 100% /proc > > the "/" Used 255876 kilo byte > > But when I use du -d 1 -x in / > > 77 ./dev > 93796 ./usr > 1812 ./stand > 861 ./etc > 1 ./proc > 3965 ./bin > 714 ./boot > 1 ./mnt > 5193 ./modules > 4887 ./root > 11776 ./sbin > 17965 ./tmp > 2468 ./var > 4 ./modules.old > 2 ./ftp > 1 ./mnt2 > 1 ./backup > 1 ./backup2 > 49 ./lost+found > 153189 . > > I just got 153189 kilo. > > why the df output and du got the different result ? > ( I've sync many times :) What does echo $BLOCKSIZE report? What version of FreeBSD is this? With 4.5-PRE, and BLOCKSIZE set to K, I get fairly consistent df/du reporting. Also, du may report different values if you run it as a non-root user. Try doing du -r -d 1 -x and see if you get any errors about unreadable directories.
