tracker miner fs 3
Je sais realtivement peu de chose sur le process Tracker Miner FS 3 ou appelé également tracker3.
J'ai quand même remarqué que c'est un process qui prend beaucoup de ressources au niveau processeur. Il m'empêche même parfois d'utiliser le navigateur de fichier Nautilus sous Gnome. Je suis obligé d'aller dans le gestionnaire de process pour le tuer afin d'utiliser Nautilus. Voulant éliminer ces désagréments, j'ai pris le taureau par les cornes.
J'ai commencé par me dire que Tracker Miner 3 n'était pas forcément un programme utile. Logiquement, j'ai utilisé dnf avec l'option remove afin de supprimer tracker, tracker extract et Tracker Miner fs.
sudo dnf remove --purge tracker tracker-extract tracker-miner-fs
Concrètement, le programme tracker 3 a tellement de dépendance avec Gnome, que dnf me demandait de désinstaller également Nautilus et d'autres composantes que j'utilisais sous Gnome. C'était donc peine perdue et je ne pouvais pas le désinstaller. Ensuite j'ai peut-être trouvé la solution sur le forum https://forums.raspberrypi.com/viewtopic.php?t=305205 . Il est indiqué que ces lenteur peuvent provenir d'un dysfonctionnement dans le programme dû aux fichiers de configuration et base de données locale. Pour tout vous dire, grâce au programme journalctl de Linux, je trouvé quelques lignes d'erreurs concernant tracker miner 3.

2. Se positionner dans .config/autostart/
cd ~/.config/autostart/
3. copie les fichiers de configurations
cp -v /etc/xdg/autostart/tracker-miner-*.desktop ./
4. Réinitialiser le cache de miner tracker qui se trouve dans le dossier courant de l'utilisateur.
rm -fr ~/.cache/tracker ~/.local/share/tracker
5. Démarrage de tracker 3
sudo tracker3 daemon -s
Il existe même l'option- W qui permet en temps réel de suivre l'évolution du programme tracker 3.
