Hi I am using Centos 5.1 and I have a weird problem with squid logs rotation. I have the file squid as follow in /etc/logrotate.d:

Recently I reduce size parameter.

/var/log/squid/access.log { weekly missingok rotate 10 compress create 0660 squid squid missingok size 200M postrotate /usr/sbin/squid -k rotate endscript } /var/log/squid/cache.log { weekly rotate 5 copytruncate compress notifempty missingok }

/var/log/squid/store.log { missingok weekly compress size 200M create 0660 root squid rotate 4 # This script asks squid to rotate its logs on its own. # Restarting squid is a long process and it is not worth # doing it just to rotate logs postrotate /usr/sbin/squid -k rotate endscript }

logrotate -vvv -f /etc/logrotate.d/squid reading config file /etc/logrotate.d/squid reading config info for /var/log/squid/access.log reading config info for /var/log/squid/cache.log reading config info for /var/log/squid/store.log

Handling 3 logs

The strange thing is that I get the following files:

[root@fido ~]# ls -lhtr /var/log/squid total 409M -rw-rw---- 1 root root 323M May 26 04:21 store.log.4.gz -rw-r--r-- 1 root root 12K Jun 11 15:40 squid.out -rw-r--r-- 1 root root 29M Jul 7 15:58 access.log.5.gz -rw-r----- 1 squid squid 367 Jul 8 04:22 cache.log.4.gz -rw-r--r-- 1 squid squid 28M Jul 8 04:22 access.log.4.gz -rw-r----- 1 squid squid 367 Jul 8 09:31 cache.log.3.gz -rw-r----- 1 squid squid 20 Jul 8 09:31 access.log.3.gz -rw-r----- 1 squid squid 2.9M Jul 8 09:31 store.log.3.gz -rw-r----- 1 squid squid 1.1K Jul 8 10:21 store.log.2.gz -rw-r----- 1 squid squid 367 Jul 8 10:21 cache.log.2.gz -rw-r----- 1 squid squid 3.2M Jul 8 10:21 access.log.2.gz -rw-r----- 1 squid squid 2.0K Jul 8 10:39 cache.log.1 -rw-r----- 1 squid squid 20M Jul 8 10:45 access.log.3 -rw-rw---- 1 squid squid 0 Jul 8 10:45 access.log.1 -rw-r----- 1 squid squid 3.1K Jul 8 10:45 store.log.2 -rw-rw---- 1 root squid 0 Jul 8 10:45 store.log.0 -rw-r----- 1 squid squid 359 Jul 8 10:45 cache.log.1.gz -rw-r----- 1 squid squid 0 Jul 8 10:45 cache.log.0 -rw-r----- 1 squid squid 2.2M Jul 8 10:45 access.log.1.gz -rw-r----- 1 squid squid 11K Jul 8 10:45 access.log.0 -rw-r----- 1 squid squid 1.4M Jul 8 10:45 store.log.1.gz -rw-r----- 1 squid squid 1.9K Jul 8 10:45 cache.log -rw-r----- 1 squid squid 328K Jul 8 10:46 store.log -rw-r----- 1 squid squid 957K Jul 8 10:46 access.log

I don't understand why compress old log files but doesn't delete old non-compressed files uncompressed. Any ideas? (I've also modified create parameter for squid be owner of access logs and run by hand logrotate /etc/logrotate.d/squid to see if it repeats the case)

Thanks in advance
