I have a filter turned on to start deleting events from oldest to newest when the disk gets over 90% full. When I checked it this morning zm was down and the hard drive is full. I stopped the zm service and tried to search for events by dates and checked the box to delete the events it finds but it does not delete them.

I then search by date and check the box to delete the events and I have successfully deleted all the events for the first recorded day. When I go and check to make sure the images directory got deleted I found that they had not. Deleting the events does not free up space.

Am I doing something wrong or am I missing something. Thanks

I was deleting events with the service stopped since the hard drive was full and I didn't want it to fill it up as fast as I deleted it. Now that I have started the zm service back up it is starting to clear space on the hard drive. Can someone explain a little more about how this process works. Thanks

I have a pretty old PC handling my ZoneMinder system. I found that if i set the Purge when full option too high (>= 93%) it would sometimes not purge the data out of the drive in time. What would then happen is, my PC would run out of HDD space and consequently blow a valve.

So, I would guess, that the Purge function is not instantaneous, but rather run when it gets a chance. I'm sure that when you delete events that it sends the request to another process to do the actual deletion.

I have set my Purge to 87% and have not seen a problem in about 12 months of stable operation.

Thanks, I noticed that to that was why I had it set to 90%. I should have read better through the forums but it looks like there is a new patch out there to fix this problem or at least one close to it.

Just in case anyone needs any extra notes about how to apply the patch this is what I did on my Ubuntu Edgy system.

cd /var/www/zm
sudo wget http://www.zoneminder.com/downloads/zm- ... lter.patch
sudo patch -p0 < zm-1.22.3-filter.patch
sudo chown www-data:www-data zm_actions.php
sudo chmod 644 zm_actions.php

Not sure if it will fix the deleting problem which started working before I fixed the problem but should allow me to delete events from the filter view.

I can delete the events no problem now but I don't see the space free on my hard drive. How do you know if when you delete events if it deletes the images?

Under SYSTEM in options there is a ZM_OPT_FAST_DELETE option, which might help. I may be wrong but does this not remove event files there and then rather than waiting for the restart?

Thanks for pointing out the fast delete. It is like my filter is never run although I did a ps aux and zmfilter.pl -c is running. To delete events I have to run the purge filter and choose execute. I do this for a few days worth of events then I have to run zmaudit.pl and it goes through and frees up the space.

Any ideas why this wouldn't be working? Thanks

I deleted all other filters I had created just leaving the purge filter and rebooted the system and it seems to be back working. I'll give it a little time and see how it does.
