Re: [bitfolk] Disk full in 'df' but half-full in 'du'

recently had same problem on a system at work, kept on doing it, we'd reboot it and it'd be ok for a while, then report disk full again while du not showing more than 5% in use. Turns out a PHP program had snowballed in a bad way and was rapidly filling up /var/log/something although we couldn't see the files for some reason. I shall have to remember the "lsof | grep deleted" trick should it ever happen again. (probably doesn't happen anymore though, since the code was fixed.)
