The setup I have is a master/slave replication, both running Mariadb 10.1.13.
On the slave I noticed that the
Seconds_Behind_Master parameter is showing a delay due to some form of lagging, but the values for
Relay_Master_Log_File are the same.
I have checked that the server IDs are different, however both have the same
Slave_IO_State: Waiting for master to send event Master_Host: X.X.X.X Master_User: repl Master_Port: 3321 Connect_Retry: 60 Master_Log_File: binary_.005825 Read_Master_Log_Pos: 140625151 Relay_Log_File: mysql20-relay-bin.000145 Relay_Log_Pos: 138885256 Relay_Master_Log_File: binary_.005825 Slave_IO_Running: Yes Slave_SQL_Running: Yes Replicate_Do_DB: Replicate_Ignore_DB: Replicate_Do_Table: Replicate_Ignore_Table: Replicate_Wild_Do_Table: Replicate_Wild_Ignore_Table: Last_Errno: 0 Last_Error: Skip_Counter: 0 Exec_Master_Log_Pos: 138884970 Relay_Log_Space: 1214370105 Until_Condition: None Until_Log_File: Until_Log_Pos: 0 Master_SSL_Allowed: No Master_SSL_CA_File: Master_SSL_CA_Path: Master_SSL_Cert: Master_SSL_Cipher: Master_SSL_Key: Seconds_Behind_Master: 10056 Master_SSL_Verify_Server_Cert: No Last_IO_Errno: 0 Last_IO_Error: Last_SQL_Errno: 0 Last_SQL_Error: Replicate_Ignore_Server_Ids: Master_Server_Id: 21 Master_SSL_Crl: Master_SSL_Crlpath: Using_Gtid: Slave_Pos Gtid_IO_Pos: 0-20-34183339144 Replicate_Do_Domain_Ids: Replicate_Ignore_Domain_Ids: Parallel_Mode: conservative
Any advice on solving the lag between my master/slave setup would be appreciated. What could the root cause be?
