Si è verificato un errore durante il ripristino da un backup

Hello everyone, I need help with a failure during restoration.
I just installed Discourse and tried to restore from my backup.
Unfortunately, I encountered an error during the restoration process.
The output is as follows:

Starting restore: discourse-2024-05-04-111743-v20240425133407.tar.gz

È stata un’installazione standard e questa installazione funzionava prima che iniziassi l’installazione?

L’hai avviata dalla riga di comando o dall’interfaccia web?

C’è una piccola possibilità che sia un bug, ma sembra improbabile.

Alienazk · 9 Maggio 2024, 1:59pm

È stata un’installazione standard e ha funzionato bene prima che iniziassi il ripristino.
La prima volta, l’ho avviato dall’interfaccia web e è fallito come da immagine seguente.

La volta successiva, l’ho avviato dalla riga di comando e l’output è arrivato la seconda volta.

Alienazk · 9 Maggio 2024, 4:29pm

Credo che stia accadendo a causa del processo di ripristino in corso.
Il problema precedente è stato risolto.
Tuttavia, abbiamo riscontrato un altro problema in cui sia la nostra memoria che lo swap sono completamente utilizzati, con conseguente significativo rallentamento del nostro sito. Sto lottando per identificarne la causa.
Qualcuno potrebbe offrire qualche spunto?
Grazie mille!

pfaffman · 9 Maggio 2024, 5:23pm

La mia ipotesi è che sia semplice come aver bisogno di più RAM. Come minimo, aggiungi più swap.

Quanto è grande il tuo database?

Ed_S · 10 Maggio 2024, 4:14pm

Ci sono molti unicorni: è il numero normale, 2 per CPU, ma per soli 4G di RAM sono tanti. Suggerirei di ridurre il numero di unicorni.

Ci sono anche alcune configurazioni del kernel che potresti modificare in modo utile per migliorare l’uso della memoria virtuale. Vedi

Alienazk · 11 Maggio 2024, 3:13pm

Abbiamo bisogno di più RAM?

Ed_S · 11 Maggio 2024, 3:32pm

Il modo migliore per vedere se hai bisogno di più RAM è osservare l’attività di paging.

Io uso

vmstat 5 5

perché lascia un record che posso tagliare e incollare. Alcuni useranno top o htop.

Alienazk · 11 Maggio 2024, 3:47pm

Grazie per il suggerimento.
Che ne dici di ridurre il numero di processi Unicorn a 4?

Ed_S · 11 Maggio 2024, 4:03pm

Vale la pena provare. Dipende dal tuo traffico. Ho solo 40-50 utenti attivi giornalieri e due unicorni vanno bene.

Un altro punto: se lo swap è al massimo, dovresti aggiungere swap. Non può fare alcun danno e potrebbe salvarti dalle brutte conseguenze dei processi che vengono terminati.

Alienazk · 12 Maggio 2024, 12:31pm

Grazie!
A proposito, potremmo cambiare il numero di unicorni senza ricostruire il container?

Ed_S · 12 Maggio 2024, 8:06pm

Non credo.
