Cannot Save Images New Installation Woes

Post by retirementhome » Wed Aug 26, 2020 9:05 pm

I have a new install, and am perfectly okay starting all over if need be. Here is what I have:

I installed via the ZoneMinder Wiki for Buster.

My Intention:
  • I want ZM to store all video in /mnt/storage/
  • I want to ZM to automatically overwrite the oldest files when /mnt/storage/ is full.
  • I want ZM to record only on motion detect at as high quality as my cameras can output, with audio, and with for 1 minute before the motion detect and 1 minute after motion detect.

Currently, I get all kinds of errors at various times related to write failures. I believe ZM does not know how to handle itself. I say this because if ZM asks me for a storage location in Options :: Storage, then once I create an entry, for me "/mnt/storage/", then ZM should be intelligent enough to handle the rest of the process, to include establishing and maintaining symbolic links for new monitors, et cetera.

Here are some errors taken from ZM's logs:

Can't open /mnt/storage/4/20/08/26/13/17/04/00011-capture.jpg for writing: No such file or directory

Failed to write frame image

Can't open /mnt/storage/3/20/08/26/13/41/38/00231-capture.jpg for writing: No such file or directory

Socket /var/run/zm/zms-439280s.sock does not exist. This file is created by zms, and since it does not exist, either zms did not run, or zms exited early. Please check your zms logs and ensure that CGI is enabled in apache and check that the PATH_ZMS is set correctly. Make sure that ZM is actually recording. If you are trying to view a live stream and the capture process (zmc) is not running then zms will exit. Please go to ... window-etc for more information.

ANY assistance to reach my Intentions would be appreciated!

Looks like you have a PC with two hard drives. Not a problem!
While I usually do Ubuntu a Debian Buster should be pretty much the same.
You can change your existing to do the same as the below...
When you set up the OS, with both drives in the PC, Format SDA for the OS and mount as "/" Format SDB and mount as "/zmstore" Doing this at install will make things easier for you down the road.
Install Zoneminder per the WIKI.
Create a directory in zmstore: mkdir /zmstore/events
Change ownership chown www-data /zmstore/events
Change permissions chmod 755 /zmstore/events
(think I have the above correct as I usually do this via Webmin)
Back to the Zoneminder Console
Options - Storage - Add New Storage
Name zmstore
Path /zmstore/events
Next you will need a filter to delete events
Create another PurgeWhenFull filter
Archive Status equal to unarchived only
and Disk Percent equal to or greater than 95
and Storage Area equal to zmstore
Delete all matches

That should work.

When you set up a camera make sure you choose zmstore as the Storage Area and I recommend using the video writer and disabling the JPEG

Thank you for the response!

I did not get to this as fast as I wanted, but I was able to follow your instructions today. So far, it seems to be working very well! I have only added two or three cameras as tests, and they have only been live for a few minutes, but I will check on them throughout the night. I am hopeful all will be well.

Again, thank you very much for your timely and insightful response!
