Hi Olaf,
We use our mysqldump script to rotate the binlogs; it's much safer as it
allows MySQL to do the log rotate natively (if you use logrotate, MySQL
will complain that either the log doesn't exist when it expects it to,
or your slaves will bail out because they didn't know the log was
changed. It happened to us recently when we moved the log directory and
didn't update the log index.)
At 2am our backup system runs the mysqldump script with the extra
parameter --flush-logs. This causes MySQL to rotate the log it's using,
and as you found out, all slaves respond to the change without an issue.

Thanks all...
Rotating actually does not affect the slaves, they adjust to the new binlog
just fine, I guess I should have tried that first.
I will nevertheless take a closer look at logrotate...

Hi all
Is it possible to rotate just the regular (--log) log file?
I am not sure if it will be safe, but maybe with logrotate and for
/var/log/mysqld.log the "copytruncate" option for logrotate.
If I do flush-logs I have to tell my slaves that (at least I have done so in
the past, maybe I don't and the slves realizes by itself?)
I think so, b/c I've never told my slaves...
HTH,
Uwe
