purgewhenfull filter not working as expected

Post by btrotter » Wed Jul 15, 2009 6:19 am

I have the purgewhenfull filter set to run in the background and delete all events when the disk percentage is greater than or equal to 88%. It is currently sitting at 93% and staying there. If I run "df -h", I confirm the disk is at 93% full.

When I look at /var/log/messages, I see lots of messages like this:
Jul 15 02:14:37 t5cctv zmfilter[6540]: INF [Deleting event 2531]
Jul 15 02:14:37 t5cctv zmfilter[6540]: INF [Deleting event 2532]
Jul 15 02:14:37 t5cctv zmfilter[6540]: INF [Deleting event 2533]
Jul 15 02:14:37 t5cctv zmfilter[6540]: INF [Deleting event 2534]

These messages are continous. However, the disk percentage never goes down. It just sits there at 93%. I have had to go to the console a couple times lately and manually delete events to get the percentage to drop.

Any idea on where to start troubleshooting this one?

How many cameras do you have? How big is your drive?

Do you have enabled the option OPT_FAST_DELETE ?

In my purgewhenfull filter, I select the option delete all matches. If you have a lot of cameras you should increase the limit to first <limit> results only. Also remember to adjust the time how often the filters are run FILTER_EXECUTE_INTERVAL and how often to check database and filesystem consistency AUDIT_CHECK_INTERVAL. You may customize your system with all these options.

For example I have the events to end every 600 seconds, so my FILTER_EXECUTE_INTERVAL is 660 seconds, I have four cameras so I limit the filter to the first 30 results and very important my AUDIT_CHECK_INTERVAL is set to 660 seconds.

So give it a try and then show your results.
