Remove old relay logs
MySQL servers running version 4.* have a bug (here's one, maybe there are others) which results in the relay logs not being deleted. Space will eventually fill up on /a/sqldata due to this bug. You can clear out the old logs by running the utility
reset-mysql-slave hostname-here
from fenari. This stops the slave, issues a RESET SLAVE command (which automatically tosses all old relay logs and opens a fresh one) and restarts the slave.
