Aggiornamento multi-sito lascia alcuni siti non disponibili

hellekin · 11 Giugno 2021, 10:12am

Con il recente frenetico aggiornamento, che ha portato alla versione 2.8.0.beta2, è successo qualcosa di strano che sto attualmente indagando. L’effetto è che in un’installazione multi-sito, alcuni ma non tutti i siti secondari non rispondono più. Il sito principale è attivo e alcuni siti secondari funzionano normalmente.

~~Sospetto che possa essere legato al problema di discourse-calendar già segnalato sulla versione stabile, ma è solo un’ipotesi.~~

Ho trovato questo nel registro di uno dei siti:

Hai eseguito prima un git pull (non necessario se fai un rebuild invece di un bootstrap).

Un’altra ipotesi è che sia legato al tema.

Controlla i temi e i plugin. Prova la modalità sicura?

hellekin · 13 Giugno 2021, 8:56pm

Grazie @pfaffman. Ho usato rebuild (due volte) e safe-mode non ha aiutato. Attualmente sto ricostruendo su un’altra macchina per evitare il multisito e vedere se il ripristino dai backup funziona.

Aggiungo solo: le pagine pubblicate (sotto /pub) funzionano normalmente. Oh, e anche /admin… Forse posso risolvere…

Apparentemente il problema proviene da discourse-prometheus-alert-receiver, che non è abilitato per questo sito…

La riga seguente sembra essere la causa del problema. Ma dato che il plugin non è abilitato, non dovrebbe essere attivato, giusto?

Quando discourse-prometheus-alert-receiver è abilitato, il sito funziona correttamente. Quando non è abilitato, il sito si blocca. Per me sembra un bug.
