I'm not sure if it's just my version of logrotate.conf or the stock version.

I think I have the stock version, but it does not seem to work.

 

Has anyone encountered the issue where the syslogs are not rotated?

 

The reason I found it is I was updating the powerdown package to call the syslog capture/dump during logrotate.

This would call /etc/rc.d/rc.unRAID syslog to capture the current syslog to your boot flash if it is going to be rotated.

 

Here is my output.

root@Atlas /tmp #ls -l /var/log/syslog
-rw-r--r-- 1 root root 1842326 Oct  4 17:27 /var/log/syslog

root@Atlas /tmp #logrotate -v /etc/logrotate.conf
reading config file /etc/logrotate.conf
reading config info for /var/log/wtmp 
error: /etc/logrotate.conf:25 unknown unit 'K'

 

 

and my fix

root@Atlas /tmp #cat /tmp/fix.sh 
echo "Fixing broken /etc/logrotate.conf"
# set -x -v
BLINE='/bin/kill -HUP cat /var/run/syslogd.pid.*'
GLINE='/bin/kill -HUP `cat /var/run/syslogd.pid 2>/dev/null` 2>/dev/null || true'
sed --in-place=.bak -e 's/10K/10k/g' -e 's/#compress.*/compress/g' -e "s#${BLINE}#${GLINE}#g" /etc/logrotate.conf

Handling 3 logs

empty log files are rotated, only log files >= 10240 bytes are rotated, old logs are removed

  log does not need rotating

FYI this is still broke in 4.4.2

 

Combined with the problem where unRAID reports a dupe file every time it sees it and 24*7 operation you end up with ridiculous sized syslog which at best slow unRAID down and at best crash it.

 

Please fix

Fixed in next beta (4.5-beta2).

Thanks Tom.
