I've got a 3-node Percona cluster, which I've set up to be a replication slave of an old MySQL server, by replicating into node A (the others being B and C).
I can see that the cluster is functioning - if I make a change on A it is replicated to B; if I make a change on B it is replicated to A.
I can also see that the replication is working - new changes are arriving on A.
But these are not being replicated from A to B. On A I have log-slave-updates=true, and I can see mysqld-relay-bin* logfiles being produced.
Any suggestions for how I can diagnose why the consumed changes on A aren't then being passed on to the other nodes in the cluster?
