Hi All! On Ubuntu 10.04 (65 bit, Desktop) I've set up Tomcat 6.0.26. No additional and unnecessary applications are running on that OS. Maybe only mail server is a little bit heavy. On Tomcat I'm running only one application which is actually search engine(I use Compass framework), indexed pages I'm keeping as a file system on Tomcat dir (they have reasonable sizes, so no need now to think up about server storage space) I have 2 mounted devices / & /usr. But there is one issue I have. It's ok when I deploy the project on app server (OS & all app installations were new at that point) . For about 1-2 weeks I got 800 GB disk usage (have seen it on webmin) of 1 terabyte instead of max~~~ 200MB usage. Of course I forgot to remove old log files of app server(logs are very large as the customer wanted to see everything is possible to show), after deleting of them I still got smth about 600-700GB disk space usage. I reboot my app server nothing was changed, then I reboot the computer, I still had for 400-500 GB used(of /usr) . Then I started to check all dirs sizes(du --max-depth=1 -h), nothing suspicious I got. Tomcat is in /usr/share/. Didn't find anything strange in its all dirs too. This can be only the result of search engine indexing, but nothing strange in tomcat's temp dir again. But when I stopped tomcat and reboot the server, I got the real usage size 46 GB.
My question is following: Does tomcat use some kind of virtualization technology or sharing/mounting network filesystem? Or what kind of reason can be for such behavior and how to fix? Thanks! Astghik
