Directory List for Charts
It would be nice if we can specify list of directories for the charts. This could be useful to put the chart on a separate partition and also share them with OpenCPN.
Do you talk about the charts that you directly use in AvNav (for o-charts you can already easily share them with OpenCPN)? Currently you can set the chart directory at AVNHttpServer... Something like
<AVNHttpServer>
....
<Directory path="/my/special/folder/for/charts" urlpath="maps"/>
</AVNHttpServer>
Just refer to the existing avnav_server.xml for the current values. You can use the update plugin to edit the config file. But multiple chart dirs are still not possible....
Hello,
I did what you suggested : Specify a path for the Maps (on a different partition) There is a mbtiles file in the specified directory. I did restart AVNav server and refresh the web page, but I do not see the map. Any idea ???
By the way, it seems that the ChartHandler is still pointing to the old chart directory.
Regards,
Ok, I have to cross check. Basically this is no "official" way of doing it - so not sure if it still works.
Currently the chart dir is determined by the -c paramter when AvNav is started. You could go for a systemd service override to change this. I will have a look if this parameter can be removed in the default set up - this should make the setting from avnav_server.xml working again.
What you can do for now: Create a (systemd) config override with the following commands
sudo mkdir /etc/systemd/system/avnav.service.d
sudo nano /etc/systemd/system/avnav.service.d/zzcharts.conf
sudo systemctl daemon-reload
sudo systemctl restart avnav
When the editor (nano) is open, just insert:
[Service]
ExecStart=
ExecStart=/usr/bin/avnav -q -c /home/pi/avnav/charts2 -b /home/pi/avnav/data -t /usr/lib/avnav/raspberry/avnav_server.xml
Use the path to your chart directory for the "-c" parameter. Import to have both of the ExecStart= lines (the first one with empty parameter)! The name of the file is important to be the last one considered (zzcharts.conf in my example). This will continue to work even if I change the behavior as described later on...
Works great. Just one modification, for the "-t" parameter I used /home/pi/avnav/data/avnav_server.xml
Bad idea... -t is the template if the config file at the destination location does not exist. But maybe i missed the last part of the start command - this is the name of the config file ;-(
In /usr/lib/avnav/raspberry is empty except there is only one file : sound.sh
Ok, this is for the normal raspberry installation. If it works for you leave it as you have it.
Just an additional info : As the partition containing the charts is not completely mounted when the system try to start the AVNav service, this one fail to auto start. To solve this I did add the following lines to the "conf" file : Restart=on-failure RestartSec=60 StartLimitBurst=3 StartLimitInterval=400
With these lines, the system will try 3 times to start the service and wait 60 sec between each start.
Would be better to use correct dependencies. AvNav will happily start with an empty chart dir...
The chart dir is not empty it just does not exist. (not yet mounted) So i got the following error (in journalctl):
jun 05 13:54:27 Elshina avnav[604]: ERROR: unable to create chart dir /media/pi/Data/Charts/AVNav jun 05 13:54:27 Elshina systemd[1]: avnav.service: Main process exited, code=exited, status=1/FAILURE jun 05 13:54:27 Elshina systemd[1]: avnav.service: Failed with result 'exit-code'. jun 05 13:54:27 Elshina systemd[1]: avnav.service: Service RestartSec=100ms expired, scheduling restart.

Just check the log file - it should tell you about the chart dir. And what exactly did you do? Which version, avnav_server.xml,..
