Problème de restauration : la relation « theme_fields » n'existe pas

pfaffman · Août 23, 2018, 6:32

@tgxworld, I think this is in your wheelhouse.
Trying to restore a backup from Discourse 2.1.0.beta5 - https://github.com/discourse/discourse version 8da2d8df3d5f7196f1c267b8a664597a725241ac or "Discourse 2.1.0.beta5 - https://github.com/discourse/discourse version bed34b52b51ab903bcb7854cc1efb2bf4107ddfb" to f4ae53d52b70a6577a60388f3550f168a4706b5f

I get

I tried restoring a backup from Beta 4 and it fails the same way, so I think it’s a problem with the current Discourse restoring, not the way that backups are created.

EDIT: It looks like the first time that I restore it works, but if I restore again, it fails. I’ve not yet tested this on more than one database.

Going to have to ship this into the support category, there could be some sort of bug here, but we need a proper repro that works consistently.

Can you consistently make this fail?

Je rencontre moi aussi ce problème maintenant.

Ce que j’ai fait :

J’ai effectué une sauvegarde avec Discourse 2.5.0.beta4.

En tant que root

git clone https://github.com/discourse/discourse_docker.git /var/discourse

cd /var/discourse

cp /var/production-backup/var/discourse/containers/app.yml /var/discourse/containers/

mkdir -p /var/discourse/shared/standalone/backups/default/

cp /var/production-backup/var/discourse/shared/standalone/backups/default/whonix-forum-2020-05-21-132423-v20200506044956.tar.gz /var/discourse/shared/standalone/backups/default/

./launcher enter app

Quelque chose ne va pas avec votre sauvegarde.

Pouvez-vous l’extraire localement et la charger dans une base de données PostgreSQL ? L’archive gzip contient 2 fichiers : une sauvegarde de PostgreSQL et un répertoire uploads.

adrelanos · Mai 25, 2020, 1:43

Merci pour votre aide !

J’ai créé une nouvelle sauvegarde à partir de l’ancien serveur de production qui fonctionne toujours parfaitement.

J’ai purgé à la fois Docker et Discourse du serveur de staging plus récent. Puis j’ai réinstallé Docker et Discourse conformément aux instructions officielles. Ensuite, j’ai suivi les instructions de restauration en ligne de commande.

La sauvegarde a été créée avec docker-engine 17.05.0~ce-0~debian-stretch et doit être restaurée avec docker-ce-cli 5:19.03.9~3-0~debian-buster. Cela entraîne également une version plus récente de PostgreSQL (ancienne : 10 ; nouvelle : 12).

Est-ce une approche légitime de sauvegarder une version obsolète de Docker/PostgreSQL et de tenter une restauration sur une installation Docker/Discourse à jour ?

Cette fois, j’obtiens une erreur différente.

Je me demande comment c’est possible puisque mon ancien serveur de production Discourse fonctionne toujours parfaitement. Et c’est la deuxième sauvegarde que j’essaie.

PostgreSQL 10 ou PostgreSQL 12 ?

Oui, cela est pris en charge.

Je vois ce message se répéter à de nombreuses reprises dans mon journal d’application. Je ne suis pas clair sur ce qui le déclenche. J’utilise PostgreSQL 9.6, au cas où cela aurait de l’importance.

Utilisez-vous la dernière version de Discourse ? S’agit-il d’une mise à niveau depuis une version très ancienne de Discourse ?

Crell · Juin 5, 2020, 2:38

Ceci est une toute nouvelle installation fraîche de Discourse 2.4, sans aucune version précédente.

J’ai également essayé de passer à Postgres 12. L’erreur apparaît toujours dans mes journaux.
