При восстановлении из резервной копии произошла ошибка

[Alienazk]

Всем привет, нужна помощь с ошибкой при восстановлении.
Я только что установил Discourse и попытался восстановить данные из резервной копии.
К сожалению, в процессе восстановления возникла ошибка.
Вывод следующий:

Начало восстановления: discourse-2024-05-04-111743-v20240425133407.tar.gz

Огромное спасибо

[pfaffman (Jay Pfaffman)]

Это была стандартная установка, и работала ли она до того, как вы начали процесс установки?

Вы запускали её через командную строку или веб-интерфейс?

Вероятность того, что это ошибка, невелика, но она всё же существует.

[Alienazk]

Это была стандартная установка, и она работала нормально, пока я не начал восстановление.
В первый раз я запустил его через веб-интерфейс, и он не сработал, как показано на скриншоте ниже.

В следующий раз я запустил его из командной строки, и вывод появился во второй раз.

[Alienazk]

Я считаю, что это происходит из-за текущего процесса восстановления.
Предыдущая проблема была решена.
Однако мы столкнулись с другой проблемой: и наша оперативная память, и файл подкачки полностью загружены, что привело к значительному замедлению работы нашего сайта. Мне трудно определить причину.
Не мог бы кто-нибудь дать какие-либо советы?
Большое спасибо!

[pfaffman (Jay Pfaffman)]

Мой прогноз таков: проблема, скорее всего, в том, что вам не хватает оперативной памяти. Как минимум, увеличьте размер файла подкачки.

Какого размера ваша база данных?

[Ed_S]

Это много единорогов — это нормальное количество, 2 на процессор, но для всего 4 ГБ ОЗУ это много. Я бы предложил уменьшить количество единорогов.

Также есть некоторые настройки ядра, которые можно полезно изменить для улучшения использования виртуальной памяти. См.

@Ed S

Но также возникает вопрос о настраиваемых параметрах ядра, упомянутых в
Мнении о конфигурации развёртывания Discourse от MKJ
которые у меня настроены правильно, но, возможно, у многих людей они настроены неправильно.

[Alienazk]

Нам нужно больше оперативной памяти?

[Ed_S]

Лучший способ определить, нужно ли вам больше оперативной памяти, — следить за активностью подкачки.

Я использую

vmstat 5 5

потому что это оставляет запись, которую я могу скопировать и вставить. Некоторые используют top или htop.

[Alienazk]

Спасибо за предложение.
Как насчет уменьшения количества процессов Unicorn до 4?

[Ed_S]

@Alienazk

Уменьшение количества процессов Unicorn

Стоит попробовать. Это зависит от вашего трафика. У меня всего 40–50 активных пользователей в день, и двух процессов Unicorn достаточно.

Ещё один момент: если своп полностью заполнен, следует добавить своп-файл. Это не нанесёт вреда, а может уберечь от негативных последствий, связанных с завершением процессов.

[Alienazk]

Спасибо!
Кстати, можно ли изменить количество единорогов без пересборки контейнера?

[Ed_S]

@Alienazk

Изменить количество единорогов без пересборки контейнера

Я так не думаю.
