зависание магазина при восстановлении на набор реплик

Question

Со следующими .mongorc.js:

rs.slaveOk();

function startRS() {
    config = {_id: 'rs', members: [{_id: 0, host: 'localhost:27017', priority: 1}, {_id: 1, host: 'localhost:27016', priority: 0}]};
    rs.initiate(config);
}

И следующий скрипт запуска:

#!/bin/bash

mkdir /data/db/rs{0,1} >/dev/null 2>&1

/opt/mongo-db/bin/mongod --replSet rs --port 27016 --dbpath /data/db/rs1 &

/opt/mongo-db/bin/mongod --replSet rs --port 27017 --dbpath /data/db/rs0 &

/opt/mongo-db/bin/mongo --eval "startRS()"

Монго запускается все нормально. Но когда я пытаюсь запустить mongorestore как

$ /opt/mongo-db/bin/mongorestore  --drop dump/

зависает при непрерывной записи

Это на MacOS High Sierra с mongodb-osx-x86_64-enterprise-3.6.5

У меня есть такая точная (вероятно, не точная, поскольку она работает) установка, работающая на другом Mac, также с MacOS High Sierra, но, вероятно, с mongodb-3.6.4.

Какие-нибудь советы?

Answer 1

Ваша командная строка mongorestore подключается к автономному mongod на локальном хосте через порт по умолчанию, размещенный вами фрагмент журнала указывает на дополнительный узел, который не сможет принимать записи.

Для того чтобы monorestore автоматически переключался на доступный для записи узел, вам нужно будет указать набор реплик в командной строке

connection options:
-h, --host=<hostname>                                     mongodb host to connect to (setname/host1,host2 for replica sets)
--port=<port>                                         server port (can also use --host hostname:port)

как

/opt/mongo-db/bin/mongorestore --host=rs/localhost:27017,localhost:27016 --drop dump/
