Need Help with Script for Synology? Dvr Crashed nothing recorded

Channels DVR Server
#1

I had the dvr crash on me last night and did not record anything lastnight .. I have written a script to check if dvr is running but I need the location of the service to start it. I use a similar script to check other services and works great.

service=channels-dvr
if (( $(ps -ef | grep -v grep | grep $service | wc -l) > 0 ))
then
echo "$service is running!!!"
else
/etc/init.d/$service start
fi

Thanks for reporting this crash. It has been fixed in the latest version.

The synology uses a start-stop-status file that's part of the DVR spk package. I'm not sure where they put it however, and it also requires specific environment variables to be set before you can invoke it.

#3

Thanks .. We need some kind of notification when it crashes as I lost a full day of Prime recording. I will see if I can find a bash script to notify me if it is not running.

#4

Most of our NAS packages will automatically restart the DVR if it crashes. The Synology package is one of the oldest and hasn't been updated to do the same.

Losing recordings really sucks- I'm sorry that happened. This is a new bug that snuck into the beta releases.

#5

I added a Scheduled task to start the Service every hour it does nothing if it is already running that will do for now until the package is updated once again Thanks.

#6

Cool. Can you paste a screenshot of the task settings in case someone else wants to replicate it?

#7

Using Synology Task Scheduler.
