Squid3 logrotate error in Ubuntu 12.04

  • 772

In a Ubuntu 12.04 server, logrotate for Squid3 is not working. I have found the problem while noticing the partition is getting full from squid3 logs. A forced logrotate yields the following error:

~# logrotate -f /etc/logrotate.d/squid3
error: error running shared prerotate script for '/var/log/squid3/*.log

Here is the complete debug output: 

~# logrotate -f /etc/logrotate.d/squid3 -d
reading config file /etc/logrotate.d/squid3
reading config info for /var/log/squid3/*.log

Any idea what can be checked here? Thanks.

    As indicated by the log entries, there is an error with the prerotate scripts.

    To debug this, one can remove the scripts from the configuration and add them back one by one until the troublesome one is found.

    They can also be executed manually to see which one fail but in this case, the OP said they failed silently.

    Using logrotate -vf /etc/logrotate.d/squid3 (-v for vervose, -f for force) is another option which in this case helps getting data on the problem.

    Good documentation on logrotate can be found here:
