Der Fehler sagt aus, das er Probleme mit der mongo db also der Datenbank gibt.

Zuerst muss der Dienst gestoppt werden:

service unifi stop

In einigen Fällen, in denen das Journal beschädigt ist, ist es hilfreich, den folgenden Befehl auszuführen, bevor die Datenbank repariert wird, um sie an einen anderen Ort zu verschieben

mv -vi /usr/lib/unifi/data/db/journal /usr/lib/unifi/data/db/journal-$(date -I)

Reparieren Sie die Datenbank mit diesem Befehl:

mongod --dbpath /usr/lib/unifi/data/db --logpath /usr/lib/unifi/logs/mongod.log --repair

Starten Sie schließlich den UniFi-Dienst neu

service unifi start

Hinweis: Wenn dieser Prozess als Root durchgeführt wurde, hat sich der Dateibesitz möglicherweise geändert. Dies kann geändert werden mit:

chown -R unifi:unifi /usr/lib/unifi/data/db/
chown -R unifi:unifi /usr/lib/unifi/logs/
