I maintain Linux server being used for Mail, Squid and DNS service. Recently I observed that something was eating server disk space. But at last, today I caught the culprit which was consuming the disk by storing large number of files.
On this server, Webmin 1.300 is installed. We use Squid proxy and Sarg to monitor Internet access. I always manually clear Sarg generated files under /var/www/html/squid for last few years.
But I never realized that Webmin is also storing some kind of bandwidth log files in its' directory structure. I have noticed that under /etc/webmin/bandwidth/hours it has stored more thousands of files since year 2007 totaling about 17 GB. We have used 40 GB HDD for this server machine.
My question is how can I delete those (/etc/webmin/bandwidth/hours) files safely?
