We are running into an issue where many events including recent events that have written to the DB but cannot be found on the disk. Looking in the events directory for the monitor seems to confirm this. Attempting to view through the browser console results in the standard broken image link.
Not sure what could be causing this and I'm hoping to get some help. Below are the system setup details:
Running Zoneminder 1.30.4. Using 150 IP cameras / ffmepg / modect / 4fps / with zones.
Had opt_fast_delete on (switched it off to troubleshoot issue)
Additionally audit_min_age is set to: 2592000
run_audit is checked and interval is 3600.
I also have a purge filter which is set to delete events older than 30days.
Events in DB but not on Disk
Re: Events in DB but not on Disk
A little more information on this. We had footage archived just a couple of days ago. After attempting to replay the footage we receive the image broken link in the web console. All DB data related to the footage is listed however the footage is gone.
Re: Events in DB but not on Disk
this sounds like the zmaudit.pl has gone awry.
Re: Events in DB but not on Disk
Might be an issue with the database. Suggest run mysqltuner to see what it recommends. With a lot of cameras connections may need to be 500 or greater (I run 1000 for 17 cameras and half dozen PC'c viewing montage)
Re: Events in DB but not on Disk
max connections is currently set to 1000. You think that might need to be higher?
Re: Events in DB but not on Disk
Well, run mysqltuner to see. If you really have 150 cameras you will need to push other mysql settings up as well. My system with 17 cameras gets aboit 60k events i. 30 days. Need to have innodb_buffer_pool_size set to 1G to work well. Do not remember other settings that have been changed but mysqtuner will tell you...
Re: Events in DB but not on Disk
Made suggested adjustments from mysqltunner.
We total 813928 events in 30 days. Any idea why zmaudit (i assume it's zmaudit) would delete disk items even though the still exist in the DB, including archived items which are specifically set to not be deleted.

Re: Events in DB but not on Disk
There is no reason for zmaudit to delete the disk items. It would have deleted the database event too.
I suspect that the images are not being created in the first place.

Re: Events in DB but not on Disk
I'm not sure I agree with that. There was an event that was archived, viewed and downloaded to the users computer. Coming back to the archived event in zm just few hours later and the data is gone while the DB information is still intact.
Re: Events in DB but not on Disk
yes it can, I have experienced this happening! But it was not zmaudit.pl that did this ....it was the Filters and something was causing /usr/share/zoneminder/www/skins/classic/views/filter.php and /usr/share/zoneminder/www/skins/classic/views/filtersave.php to almost immediatley after an event creation just delete it. the actual event data was erased and some of the database info related to these events was gone but some of it was not. I think I started to look into it...There is no reason for zmaudit to delete the disk items. It would have deleted the database event too.
I would suggest looking into what the Filters are doing!
Re: Events in DB but not on Disk
looking at my notes the time it took for the events to be deleted by the Purge when full filter varied from almost immediately to up to an hour later. I turned off the filter(s) running in the background and it stopped. I never went any deeper on that install to find a good fix.
