Piaware 4.0 SD-image
This image has been running for a few years without issue. Today only the status.json and piaware.pid file are being written to the /var/run/piaware directory. The /var/run/dump1090-fa cirectory has the a bunch of history_xx.json files as well as aircraft, receiver, and stats. Both directories are updating every few seconds.
I tried a workaround creating symlinks to the missing files via:
sudo ln -s /var/run/dump1090-fa/.json /var/run/piaware/.json,
sudo chown -h piaware:piaware .json to correct the permissions.
This successfully created the symlinks but there were not accessible via browser, returning 404.
I rebooted the unit and it is still not creating these files in the /var/run/piaware folder.
No configuration change, power event, crash, etc. occurred prior to this issue. The unit was rebooted on 2/20/2021 and was working properly afterwards.
The SD is not full or out of inodes:
