You deleted old logs. Is the size of the directory before or after you 
deleted the logs? How much did you delete? Is there currently a 
discrepency between df and du? Did any of the files you deleted happen 
to be in use? (If those files are still in use, then their space hasn't 
been freed yet -- they're simply no longer linked into their directory. 
usually SIGHUPping daemons makes them close and reopen all of their 
file descriptors which will cause you to recover your space)
