Running start slave yields this: ERROR 1201 (HY000): Could not initialize master info structure; more error messages could not can be found in the MySQL error log Enabling the log yielded nothing. Googling yielded This Page that helped me a lot, but I didn't have to do quite as much work all over again. Here is what I did. First, I saved my "SHOW SLAVE STATUS\G" output: ************************** 1. row master info structure ************************** Slave_IO_State: Master_Host: 127.0.0.1 Master_User: replication Master_Port: 3307 Connect_Retry: 60 Master_Log_File: mysqld-bin.000401 Read_Master_Log_Pos: 98 Relay_Log_File: mysqld-relay-bin.006135 Relay_Log_Pos: 242 Relay_Master_Log_File: mysqld-bin.000401 Slave_IO_Running: No Slave_SQL_Running: No 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: 98 Relay_Log_Space: 0 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: NULL 1 row in set (0.00 sec) Next I followed instructions from the blog I mentioned above: STOP SLAVE; RESET SLAVE; Instead of fully reconfiguring I simply tried to start slave. This is a bad idea because it seems to just try to start slaving off the front of the first binlog file it finds, getting conflicts (or worse). So I tried something simple: mysql> CHANGE MASTER TO MASTER_LOG_POS=98 , MASTER_LOG_FILE = 'mysqld-bin.000401'; Query OK, 0 rows affected (0.04 sec) mysql> start slave; Query OK, 0 rows affected (0.00 sec) The position comes from the output I saved be

Everything is working okay, EXCEPT if the slave server i down more than a few hours/days, I can't restart the slave process. The error message is ERROR 1201 (HY000): Could not initialize master info structure; and [ERROR]Failed to open the relay log '/var/run/mysqld/....' [ERROR] Could not find target log during relay log initialization As I understand, the logs get flushed after prolonged downtime/reboot. Is it any way I can configure the slave server, so that it'll catch up with the master server, without me having to get a new snapshot/master position etc (which is a cumbersome process). - The slave already knows the last position it has reached at the master, so I do not understand the significance of the relay log... Does it make a difference whether the slave is STOPped before stopping the mysqld service? Thanks for your help! Edited 1 time(s). Last edit at 04/23/2009 07:03AM by Rasmus U.
