Directory Events magically disappeared!

[garbia]

Hello everybody
I am having this issue in my 1.32.4 installation which was stable until a couple of days ago when I went to play one of the cameras and realized that nothing was playing.

Getting a black screen with
"The video could not be loaded, either because the server or network failed or because the format is not supported"
Live monitoring works, haven't touching anything from Nov 14 when the recording were playing without problems.

Steps:
1) Restart the VM
2) Permissions
#chown -R www-data:www-data /etc/zm
#chown -R www-data:www-data /var/cache/zoneminder
3) checked the logs and found out that events wasn't there anymore!

Solved by creating the directory events.

I am using VMware and ubuntu server 18.04

Hi, what type of video writer do you use? I had the same issues when i configured my monitor's video writer to H264 Camera Passthrough.

Thank you for your reply
I did a fresh 1.32.4 installation installation, pretty much all default, couple of foscams, rest is Ezviz
It looks like an ownership problem, if thats the case, I have no idea how that happened


This is from the log
2018-11-20 16:50:55 zmfilter_2 1611 WAR DiskSpace: Event does not exist at /var/cache/zoneminder/events/3/2018-11-19/9595:ZoneMinder::Event: Name => Event- 9595 StateId => 1 EndTime => 2018-11-19 23:25:28 Frames => 1084 StartTime => 2018-11-19 23:20:00 Id => 9595 Cause => Continuous MonitorId => 3 Height => 960 StorageId => 1 Width => 1280 Length => 328.89 DefaultVideo => 9595-video.mp4 zmfilter.pl

I'll add to this issue. I'm running UB18.04 ZM1.32.2 FreeNAS event storage over NFS.
My events are recorded as H264 passthrough triggered (Nodetect) by low res stream on modetect.

The actual video files are not in the event directory. The snapshot and thumbnail are though.
It doesn't happen all the time for me so it's a hit and miss thing.

I thought it might be an issue with the Hikvision cams.

I meant to spend some more time observing the problem and trying to find out definitively if using the h264 record mode as opposed to passthrough fixes the issue. Just haven't gotten there yet.

What I've observed so far:
- Not all evetns, but hit and miss. don't know the circumstances that cause the problem
- Video file definitely missing in event dir
- LowRes trigger monitor recorded trad mjpeg just fine
- Seems to only happen on hires monitors larger than 1920x1080

What I am trying to understand is how the whole event dir disappeared, as strange as it sound......




root@zoneminder:/var/cache/zoneminder# dir
cache images temp
root@zoneminder:/var/cache/zoneminder# ls -l
total 24
drwxr-xr-x 2 www-data www-data 16384 Nov 19 14:18 cache

Different problem, in my case the whole events directory is gone!

I'm having this "disappearing events directory" issue with v1.32.3 on ubuntu 18.04.
It's happened three times already!?!?

The recovery is to create the directory back, but that's not a fix. All events are lost.

[karsta62]

Right. I got the events directory protected, but just now I was cleaning up events, and suddenly all events from all monitors vanished.
I can only clean one monitor at a time so it's no accident. I saw many events from every monitor, but now they are all zero.
The "events" directory exists as well as the monitor number directories, but all empty.

This is what's in the log:
