After nearly running out of space on my /var partition recently, I went in to clean things up and ensure that it didn't happen again. Using the "du" command to look for offending directories and files, I wiped out a bunch of old Apache and Qmail logs...and then found that I was still using 90% of the partition. So I cd'd over to /var, and got this rather surprising set of results: [alex@tms /var]$ sudo du -sh 395M . [alex@tms /var]$ df -h Filesystem Size Used Avail Capacity Mounted on /dev/ad4s1a 484M 126M 320M 28% / devfs 1.0K 1.0K 0B 100% /dev /dev/ad4s1f 269G 40G 207G 16% /data /dev/ad4s1d 9.7G 7.2G 1.7G 81% /usr /dev/ad4s1e 1.9G 1.6G 173M 90% /var These wildly different results have me confused. How in the world can there be a ~1.2GB difference between the disk space in use as reported by these two tools? Which is right? More importantly, how do I fix this? Thanks, Alex Kirk
