Watchdog ocassionally stops reacting to changes on filesystems

[pulpul-s]

After running the script for longer times e.g. three days, watchdog does not react to filesystem changes anymore. This seems like an issue with the watchdog library itself rather than a problem with watchertoucher.

At the moment the only reasonable fix is to run the script as a systemd service and have it restart every 24 hours. This does not cause any downtime.

Any help on the issue is appreciated, since I have been unable to fix it completely.

@pulpul-s Has this solution been adequate for you for the past few months? I'm running my Jellyfin scans every 15 mins but this seems like a better solution, though I do not want to tinker around much. If setting this as a service with auto restart has been flawless for the past few months I think I'd bite the bullet.

Yes.

I have been running it as once a day restarting service for quite some time now and have not observed any times that the library would not update like it is supposed to.

The python script takes quite a while for it to fully boot up for me and I'm not sure why. It also never seems to start with systemd. This is my config:

Description=Watchertoucher Service
After=network.target

[Service]
Type=simple
ExecStart=/usr/bin/python3 /etc/watchertoucher/watchertoucher.py
Restart=always
RestartSec=24h

[Install]
WantedBy=default.target

I'm running this on an ubuntu 22.04 install that just has docker, and a jellyfin container.

Try to make sure you don't have any problems with the configuration options in the start of the script. Also try to run it normally without it being a service first to check that it works like it is supposed to. You can just try to create files to the watched filesystem with: touch test.mkv and see if the scripts sees it.

This is the systemd service I'm using currently:

[Unit]
Description=watchertoucher for jellyfin service
After=systemd-networkd-wait-online.service mediaserver-libraries-null\x2dnull.mount

[Service]
Restart=always
RestartSec=1
RuntimeMaxSec=1d
User=root
ExecStart=nice -n 17 /usr/sbin/watchertoucher.py

[Install]
WantedBy=multi-user.target
