Actualización fallida de 2.7.0.beta1 a 2.7.0.beta3

Utilicé la actualización del navegador con un solo clic para intentar actualizar de 2.7.0.beta1 a 2.7.0.beta3.

Primero actualizó Docker, aparentemente con éxito. Luego, según las instrucciones, ejecuté lo siguiente en el servidor:

    cd /var/discourse
    git pull
    ./launcher rebuild app

Se completó y me indicó que era necesario volver a reconstruir. Así que lo hice, y el proceso avanzó bastante antes de mostrar lo siguiente:

./discourse-doctor may help diagnose the problem.

Las notas de la versión advertían sobre PostgreSQL y el espacio en disco; ¿quizás falló por esa razón? Cuando ejecuto discourse-doctor, la salida incluye:

---------- OS Disk Space ----------

/dev/disk/by-label/DOROOT   30G   20G  8.5G  70% /

¿Qué debo hacer ahora?

¿Puedes pegar más líneas de la salida de la reconstrucción? Necesitamos algunas líneas anteriores a esa para poder solucionar el problema.

Parece que el culpable podría ser:

failed_discourse_upgrade_2021_01_31.txt (90.4 KB)

Ha habido algunos temas recientes sobre la corrección de duplicados. Ejemplo:

Gracias. Tengo problemas para que psql funcione.

Reinicié el contenedor:

./launcher start app

Luego ejecuté:

./launcher enter app

y después:

su postgres -c 'psql discourse'

Pero la salida fue:

psql: error: no se pudo conectar al servidor: no se pudo conectar al servidor: No existe tal archivo o directorio
¿Está el servidor ejecutándose localmente y aceptando
conexiones en el socket de dominio Unix “/var/run/postgresql/.s.PGSQL.5432”?

Prueba sudo -u postgres psql discourse

Intenta sudo -u postgres psql discourse

La misma mensaje de error, lamentablemente.

¿Se ejecutó correctamente la primera iteración de la reconstrucción del launcher?

Si fue así, tu base de datos ya fue actualizada a PostgreSQL 13, mientras que los binarios de PostgreSQL en la imagen de la aplicación antigua aún esperan una versión de base de datos 10 o 12, dependiendo de la versión desde la que estás actualizando.

cd /var/discourse/shared/standalone
ls -alh

¿Tienes ambos directorios postgres_data y postgres_data_old?

Asegúrate de que la aplicación esté detenida, luego mueve o cambia el nombre (no lo elimines todavía, solo por seguridad) del directorio postgres_data, y luego

mv postgres_data_old postgres_data

Y luego intenta ejecutar launcher start app nuevamente.

¡Espero que esto ayude!

Gunnar

Seguí estos pasos y renombré correctamente al usuario duplicado. Pero luego encontré este problema al intentar volver a indexar.

@sam había sugerido en ese hilo: “Sí, por favor, elimina las filas duplicadas”, pero no sé qué significa eso en el contexto de las advertencias y los mensajes de error que obtengo al volver a indexar, lo cual ahora ha crecido hasta convertirse en:

REINDEX SCHEMA CONCURRENTLY public;

DETAIL:  Key (path, incoming_domain_id)=(/votes/, 1165) is duplicated.

Esos son índices temporales que se crearon mientras se estaba ejecutando el reindexado. Cada vez que fallaba debido a duplicados, dejaba al menos un índice temporal. Puedes identificarlos por el nombre, que termina en ccnew, ccnew1, ccnew2, y así sucesivamente.

Puedes eliminarlos entrando a Psql y ejecutando el comando DROP INDEX.

sudo ./launcher enter app
su postgres -c 'psql discourse'

DROP INDEX '<nombre_del_indice>_ccnew';
DROP INDEX '<nombre_del_indice>_ccnew1';

Y así sucesivamente. Asegúrate de tener una copia de seguridad de la base de datos primero, verifica que el reindexado no se esté ejecutando actualmente y asegúrate de que solo elimines los índices _ccnew.

Más información en esta publicación:

Thanks again, Gunnar. I was able to drop some of the ccnew indexes but not all:

In any case, I seem to have successfully reindexed afterwards:

discourse=# REINDEX SCHEMA CONCURRENTLY public;
REINDEX

So then I went to complete the upgrade, but it failed:

I don’t know why the rebuild failed, except that it appears to have something to do with Postgres. I don’t know where the log file “pg_upgrade_dump_16566.log” is supposed to be.

Ideas?

Creo que eso significa que la actualización no funcionó. Yo tuve un trabajo similar ayer.

Lo que hice, creo, fue mover los datos de respaldo de nuevo a postgres_data, luego cambiar a la plantilla pg10 (¿probablemente 12 para ti?), luego reconstruir, y después volver a cambiar la plantilla y reconstruir dos veces más para la actualización.

Eso son los puntos principales, pero es lo mejor que puedo hacer desde mi teléfono. La actualización de PostgreSQL 13 debería tener todo lo que necesitas.

Lo que hice, creo, fue mover los datos de la copia de seguridad de nuevo a postgres_data, luego cambiar a la plantilla pg10 (probablemente 12 para ti?), luego reconstruir, y finalmente cambiar la plantilla de nuevo y reconstruir dos veces más para la actualización.

Así que déjame ver si entiendo. Necesito:

  1. Renombrar postgres_data a algo más y luego renombrar la copia de seguridad que hice a postgres_data.
  2. Renombrar postgres.template.yml a algo más y luego renombrar postgres.12.template.yml a postgres.template.yml.
  3. Ejecutar ./launcher rebuild app.
  4. Restaurar tanto postgres_data como postgres.template.yml.
  5. Ejecutar ./launcher rebuild app.
  6. Ejecutar ./launcher rebuild app.

¿Es eso correcto?

Hola Roger. Debería ser algo muy parecido a eso, pero no conozco exactamente tu situación, así que no puedo prometértelo.

Ah, espera.

No. En el archivo app.yml deberías hacer referencia a la plantilla de PostgreSQL 12 en lugar de la plantilla estándar de PostgreSQL. Estás editando tu app.yml, no renombrando archivos. Creo que la guía de actualización lo explica bastante bien.

Para el sitio que acabo de reparar, el directorio postgres_data estaba vacío y luego (creo) que mi script ejecutó un docker prune, lo que eliminó el contenedor que, creo, habría funcionado si simplemente lo hubiera reiniciado.

Si solo quieres que se solucione y tienes presupuesto, consulta Redirecting….
