Have existing percona cluster and new percona cluster. Both have a few slight configuration differences. Would like to know functionality wise, what the difference is, if any.
Cluster A - 3 nodes , my.cnf file server_id is respectively 1, 2 and 3 . does server id have any effect on if servers are rebooted?
Cluster B - 3 nodes +DR asynchronous replication host. Server_id for 3 nodes is the same. and server_id is different than the other 3 nodes on DR node. how do reboots work in this scenario since these server nodes are same server_id’s? If no different that’s fine. Just trying to clarify if there is any difference between 2 clusters in this regard.
