MariaDB Error 1610: Corrupted Replication Event Detected
Description
Error 1610 indicates that the MariaDB replica server encountered a malformed or unreadable event while processing its replication logs. This critical error halts replication, preventing the replica from synchronizing further changes from the source. It signifies data integrity issues within the binary or relay log files.
Error Message
Corrupted replication event was detected
Known Causes
3 known causesDisk Corruption
Physical damage or logical errors on the disk where binary logs (source) or relay logs (replica) are stored can lead to corrupted event data.
Server Crashes or Software Bugs
An abrupt shutdown of the source or replica server, or a bug in the MariaDB server software, can result in partially written or malformed replication events in the logs.
External Log Modification
If external tools or processes modify MariaDB's binary or relay log files directly, it can introduce inconsistencies and corrupt replication events.
Solutions
3 solutions available1. Restart the Replica Server easy
A simple restart can sometimes resolve transient replication issues.
1
Connect to the replica server via SSH or your preferred terminal.
2
Gracefully stop the MariaDB service.
sudo systemctl stop mariadb3
Wait a few seconds for the service to fully shut down.
4
Start the MariaDB service again.
sudo systemctl start mariadb5
Check the replica status to see if the error is resolved. You can use `SHOW REPLICA STATUS;` in the MariaDB client.
SHOW REPLICA STATUS;2. Skip Corrupted Event medium
This is a quick fix to bypass a single corrupted event, but it can lead to data divergence.
1
Connect to the replica server using the MariaDB client.
2
Execute `SHOW REPLICA STATUS;` to identify the `Relay_Log_File` and `Relay_Log_Pos` of the corrupted event. Note the `Exec_Master_Log_Pos` as well.
SHOW REPLICA STATUS;3
Use the `SET GLOBAL` command to skip the corrupted event. Replace `[position]` with the `Exec_Master_Log_Pos` value from the previous step.
SET GLOBAL SQL_SLAVE_SKIP_COUNTER = 1;4
Immediately restart the replica to re-evaluate its state.
STOP REPLICA;
START REPLICA;5
Verify the replica status. If the error persists, you might need to skip more events or consider a more robust solution.
SHOW REPLICA STATUS;3. Rebuild Replica from Master Dump advanced
A more thorough solution that ensures data consistency by re-initializing the replica.
1
On the **master** server, ensure binary logging is enabled and configured correctly. Check `my.cnf` or `my.ini` for `log_bin` and `server_id`.
2
On the **master** server, create a full backup of your database. This is crucial for recovery. Use `mysqldump` for this purpose.
mysqldump --all-databases --master-data=2 --single-transaction > master_backup.sql3
On the **replica** server, stop replication.
STOP REPLICA;4
On the **replica** server, drop all existing databases (if you are sure this is acceptable) or at least the databases being replicated.
DROP DATABASE IF EXISTS your_database_name;5
Transfer the `master_backup.sql` file from the master to the replica server.
6
On the **replica** server, import the backup.
mysql < master_backup.sql7
On the **replica** server, find the `CHANGE MASTER TO` (or `CHANGE REPLICATION SOURCE TO` for newer versions) statement from the `master_backup.sql` file. It will look something like this, but with your specific master details:
-- CHANGE MASTER TO MASTER_HOST='your_master_ip', MASTER_USER='replication_user', MASTER_PASSWORD='your_password', MASTER_LOG_FILE='master-bin.XXXXXX', MASTER_LOG_POS=XXXXXX;8
On the **replica** server, configure replication using the information from the backup.
CHANGE REPLICATION SOURCE TO SOURCE_HOST='your_master_ip', SOURCE_USER='replication_user', SOURCE_PASSWORD='your_password', SOURCE_LOG_FILE='master-bin.XXXXXX', SOURCE_LOG_POS=XXXXXX;9
On the **replica** server, start replication.
START REPLICA;10
Verify the replica status.
SHOW REPLICA STATUS;
