logrotate problems

[Mario Caisapanta]

I have installed logrotate to rotate some system logs.
I was testing logrotate with mail.log. It worked because I got a log named mail.log.1 but the new log (mail.log) is 0kb and I have sent some mails.

Thx for your help...

regards

How does your logrotate work?

Does it copy or move the file? If it moves (mv) it and your mail application has the log file open, then the mail application is still pointing to the OLD inode.

If it is using a (cp) and then a "cat /dev/null" to your logfile, then it's a "buffer" issue which will flush when there the buffer becomes "full".

Check the permissions of mail.log. Here is ours:
-r--r--r-- 1 root root 50021 Apr 26 00:00 mail.log

Also, below is the code we use for our log rotation. It might give you some ideas:

#!/bin/sh

mv -f /var/adm/syslog/auth.log /var/adm/syslog/auth.log.1
mv -f /var/adm/syslog/mail.log /var/adm/syslog/mail.log.1
mv -f /var/adm/syslog/syslog.log /var/adm/syslog/syslog.log.1

kill -HUP `cat /var/run/syslog.pid`

rm -f /var/adm/syslog/auth.log.1.gz
gzip /var/adm/syslog/auth.log.1
rm -f /var/adm/syslog/mail.log.1.gz
gzip /var/adm/syslog/mail.log.1
rm -f /var/adm/syslog/syslog.log.1.gz
gzip /var/adm/syslog/syslog.log.1
