Gerrit pull-replication plugin automatically sync?

[Rain JJ]

Dear all:

    I recently deployed Gerrit(3.8) multi-site. 

Currently, only 2 master R/W nodes are configured, and the following plugins are installed:

multi-site

events-rabbitmq

pull-replication

websession-broker

zookeeper-refdb

Two master R/W nodes A and B.

Now I push a change to A, but it is found that B is not synchronized (Web UI page does not have this change).

However, after I manually execute ‘ssh gerrit pull-replication start’ on node B, the change are synchronized to node B.

Why is this? Shouldn’t it be automatically synchronized to B?

Looking forward to your reply!

Hi,

What does your pull-replication config look like?
Are there any errors in the log?

Looking forward to your reply!

Sorry I forgot to upload the information !

When I push a  change to Maser A:

master  A replication.config:

[gerrit]
    autoReload = true
    replicatePermissions = true
    replicateOnStartup = false
[replication]
    lockErrorMaxRetries = 5
    maxRetries = 5
    userCGitClient = false
    consumeStreamEvents = false
    syncRefs = "ALL REFS ASYNC"
    maxApiPayloadSize = 40000
    excludeRefs = refs/multi-site/version
[remote "push_masterB"]
    url = master_B:/data/gerrit_multisite/review_site/git/${name}.git
    fetch = +refs/*:refs/*
    mirror = true
    timeout = 600
    rescheduleDelay = 2
    replicationDelay = 2
    createMissingRepositories = true
    replicateProjectDeletions = true
    replicateHiddenProjects = true
    replicatePermissions = true

master  B replication.config:

[gerrit]
