No master server available for replication after upgrade to 2.1.6

[markitosgv]

Hi,

I'm getting this error "No master server available for replication" when I upgraded from 2.1.3 to 2.1.6, but the issue was introduced in 2.1.4 release.

My snc_redis configuration is:

snc_redis:
    clients:
        front:
            type: predis
            alias: front
            dsn:
                - "%env(REDIS_MASTER_URL)%?alias=master"
                - "%env(REDIS_SLAVE_URL)%"
            logging: "%kernel.debug%"
            options:
                replication: true

Please share the actual value of those environment variables.

Hi,

The values are:

"REDIS_MASTER_URL": "redis://redis.mydomain.com",
"REDIS_SLAVE_URL": "redis://localhost",

I've a redis server on redis.mydomain.com, and a local redis. Before updating, redis master was replicated in local instances of my app

We have the same issue after upgrading from 2.1.3 to 2.1.6. Our config is as follows:

snc_redis:
    clients:
        cache:
            type: predis
            logging: '%kernel.debug%'
            alias: cache
            dsn: '%redis.dsn%'
            options:
                profile: 2.8
                replication: true
                connection_timeout: 10
                read_write_timeout: 30
    doctrine:
        query_cache:
            client: cache
            entity_manager: default
            namespace: dqc
        result_cache:
            client: cache
            entity_manager: default
            namespace: drc
        second_level_cache:
            client: cache
            entity_manager: default
            namespace: l2c

parameters:
    doctrine.orm.cache.l2.enabled: true
    redis.dsn: redis://127.0.0.1

In our scenario the issue (No master server available for replication) only occurs on a Symfony 4 installation. An almost identical implementation on the same environment using Symfony 3 did not throw any exceptions when updating to 2.1.6

@B-Galati I suppose this is yours to look into ;)

[B-Galati]

[wukchao]

Has this problem been resolved?

[kasperhendriks]
