Advanced MySQL Replication Techniques
Subject:   fail-over infinite looping problem
Date:   2007-03-09 09:00:49
From:   chazByrne
The scenario is that four servers A, B, C, and D (with server ids 1, 2, 3, and 4 respectively) replicate in a topology { A->B, B->C, C->D, D->A }. Server A crashes. The DBA wants slave B to connect to master D instead and continue with the circular replication.

The normal loop detection that MySQL has discards events that are generated on the same server, but since A is no longer in the circle, the generated events will loop forever. My current problem is an update statement from the downed server that is replicated in an infinite loop...

Is there a work around for this? Or a command I am missing.

Thank you very much,
Chaz Byrne

    There is a proposed solution here,110341,110341
    But I am not sure if/when it would be incorporated in the server.

    I too am facing the same problem and am not able to find a solution anywhere on net.

    Does anyone know if a solution exists? Otherwise it is a show stopper for circular replication.

    Thanks a lot,
