Multi-Site-Upgrade lässt _einige_ Seiten nicht verfügbar

hellekin · 11. Juni 2021 um 10:12

Bei der jüngsten Upgrade-Welle, die zu Version 2.8.0.beta2 führte, ist etwas Seltsames passiert, das ich derzeit untersuche. Das Problem besteht darin, dass bei einer Multi-Site-Installation einige, aber nicht alle sekundären Sites nicht mehr reagieren. Die primäre Site ist verfügbar, und einige sekundäre Sites funktionieren normal.

~~Ich vermute, dass dies mit dem bereits für die stabile Version gemeldeten discourse-calendar-Problem zusammenhängen könnte, aber das ist nur eine Vermutung.~~

Ich habe dies im Log einer der Seiten gefunden:

Hast du zuerst ein git pull ausgeführt (unnötig, wenn du ein Rebuild statt eines Bootstraps durchführst).

Eine weitere vage Vermutung ist, dass es themenbezogen ist.

Überprüfe Themes und Plugins. Versuche den abgesicherten Modus?

hellekin · 13. Juni 2021 um 20:56

Danke @pfaffman. Ich habe rebuild (zweimal) verwendet, und der safe-mode hat nicht geholfen. Ich baue derzeit auf einem anderen Rechner neu auf, um Multisite zu vermeiden, und prüfe, ob die Wiederherstellung aus Backups funktioniert.

Nur zur Ergänzung: Veröffentlichte Seiten (unter /pub) funktionieren normal. Oh, und /admin auch… Vielleicht kann ich das Problem lösen…

Anscheinend stammt das Problem von discourse-prometheus-alert-receiver, das für diese Site nicht aktiviert ist…

Wenn discourse-prometheus-alert-receiver aktiviert ist, funktioniert die Seite einwandfrei. Wenn es nicht aktiviert ist, funktioniert die Seite nicht. Das klingt für mich nach einem Fehler.
