Gateway 10.x, 11.x
User removed the ssg replication bin_log files to make disk space before the incident. But the bin_log index file still point to the log files that have been removed and mysql quit when try to start and could not find the sync log files.
1. Remove all the log file names in the bin_log index file
2. Restart the MySQL service
The database could be out of sync if there were any changes or deployments when the other database was down. In that case, replication may need to be reestablished.
Reinitialization of replication can be done by using this KB:
