I need to delete/purge relay-bin files from mysql server. We don’t have any space left. We are not sure if we can delete the old relay-bin files or not. Looking for adivse on what is the best approach to delete/purge the files that has filled up the server space.
Here are the mysql db details
innodb\_version: 5.5.33-rel31.1
protocol\_version: 10
slave\_type\_conversions:
version: 5.5.33-31.1-log
version\_comment: Percona Server (GPL), Release rel31.1, Revision 566
version\_compile\_machine: x86\_64
version\_compile\_os: Linux

Anil

@amereddy relay\_logs are automatically purged after they have been processed by the SQL\_thread. How is your replication lag? You can use STOP SLAVE; RESET SLAVE; START SLAVE; to delete the relay logs. Any needed logs will be re-downloaded from the master.

Thanks Matt. I have master(mysb02) and slave(mysdb04). The slave is down as it is 100% full and we could not add anymore space to /var mount. I can’t even start mysql service to execute the commands you have suggested. Is there anything else that I can do ?

At that point you can just remove the relay logs manually. When you start mysql, slave status will be invalid, but you can just restart it.

Thansk Matt. Is there is particular sequence I need to remove the relay logs ? I can safely start deleting the oldest one and go from there right ?

Just delete them all. When you get mysql back up, just stop slave; start slave; and it should re-download any missing relay logs.

Thanks Matt. that cleaned up the log files. Another question, I see is that
Slave\_IO\_State: waiting from master to send event
slave\_io\_running: yes
slave\_sql\_running: no
Not sure if I need to set anything or wait

If you have this, then replication is not working and you need to see what the error is.
