Mysql Error 1872 Slave Failed To Initialize Relay Log

Severity:S2 (Serious) Version:mysql-5.1-telco-7.1 OS:Linux (RedHad 5.4 and CentOS) Assigned error counting relay log space to: Martin Skold Tags: 7.1.3, replication, sql node restart, telco-7.1 bzr Triage: Triaged: D2 (Serious) could not find target log during relay log initialization / R6 (Needs Assessment) / E6 (Needs Assessment) View Add Comment Files Developer Edit Submission View Progress Log Contributions [15 Apr 2010 14:42] Carlos http://perplexed.co.uk/301_restoring_a_broken_slave.htm Pinera Description: We have multi-master replication between two machines. Initially the slave status shows everything is fine. After an SQL node is restarted (/etc/init.d/mysql restart), the slave on that SQL node get an error: 100413 10:15:36 [ERROR] Error reading master configuration 100413 10:15:36 [ERROR] Failed to initialize the master https://bugs.mysql.com/bug.php?id=52859 info structure This was working fine with cluster version 7.0.9 and earlier. Setting an explicit entry in my.cnf for master-info-file has no effect. For simplicity I reduced the configuration to two machines, with each machine running a single storage node. It fails the same way with the configuration of two macnines in each cluster and replication between the clusters (total of 4 machines). After the restart the storage and sql nodes are up but the slave has not started. The my.cnf file content for 'andorinha' is: # MySQL Cluster configuation file.

Run this SHOW SLAVE STATUS\G If there is any information still being presented, you need to run this CHANGE MASTER TO master_host = ''; Then, go run SHOW SLAVE STATUS\G You should get nothing and master.info should be gone. From the MySQL 5.1 Documentation If any startup options for setting connection parameters (such as master host, master port, master user, and master password) are in use, then any corresponding connection information stored in the master.info file is immediately reset using the values specified for these options. Options for which values are not specified are cleared. However, since these options are deprecated
