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,
