After checking the current stat of replication using one of the previous methods, we can use the table below to understand what each state means
Value | Meaning | Description |
---|---|---|
0 | Initialization State | This state indicates that replication is in the process of trying to setup. Being in this state for a period longer than an hour could indicate a failure in setup. |
1 | Number of Replicates not correct | This state is rarely seen in 6.x and 7.x but in 5.x can indicate its still in the setup process. Being in this state for a period longer than an hour could indicate a failure in setup. |
2 | Replication is good | Logical connections have been established and tables match the other servers on the cluster. |
3 | Tables are suspect |
Logical connections have been established but we are unsure if tables match.
In 6.x and 7.x all servers could show state 3 if one server is down in the cluster.
This can happen because the other servers are unsure if there is an update to a user facing feature that has not been passed from that sub to the other device in the cluster.
|
4 | Setup Failed / Dropped | The server no longer has an active logical connection to receive database table across. No replication is occurring in this state. |
