Hello, Recently, I've noticed that the df command has been showing negative disk space, and was wondering how far negative it could go until the /usr partition was full: Filesystem 1K-blocks Used Avail Capacity Mounted on /dev/wd0a 48431 39551 5006 89% / /dev/wd0s1 423072 392984 30088 93% /dos /dev/wd0s4e 548911 526867 -21868 104% /usr procfs 4 4 0 100% /proc But then I noticed that, for /usr, it shows -21868 avail, but when doing the math, 22044 is actually available. For /, shows 5006, but act. free space is 8880. The disk usage for /dos is right on target. Is it because df is allowing for a 'safety margin' of free space, or do I need to reboot or rebuild some database or something? Thanks for any responses Donn
