I've tried to test a dual channel replication but forgot to add +copy for my replication user. As a result replica entered silent cycle like this: ``` * Connecting to PRIMARY 127.0.0.1:6379 * PRIMARY <-> REPLICA sync started * Non blocking connect for SYNC fired the event. * Primary replied to PING, replication can continue... * Trying a partial resynchronization (request ...) * PSYNC is not possible, initialize RDB channel. * Aborting dual channel sync ``` And primary got endless cycle like this: ``` * Replica 127.0.0.1:6380 asks for synchronization * Partial resynchronization not accepted: Replication ID mismatch (Replica asked for '...', my replication IDs are '...' and '...') * Replica 127.0.0.1:6380 is capable of dual channel synchronization, and partial sync isn't possible. Full sync will continue with dedicated RDB channel. ``` There was no way to understand that replication user is missing +copy acl on notice log level. With this one-line change we get a warning message in our replica log. --------- Signed-off-by: secwall <[email protected]>

@secwall Can I ask what your use case was to manually be setting up the dual channel? |
I've been trying to test how the new features in version 8.0 work in our environment. |
