How can I manually rotate my logs. My /var/log file is taking up 15 Gb of my 20 Gb root file system. I have /home in a separate partition. I tried running logrotate from my /etc/cron.daily folder but my /var/log/syslog is still setting at 6 Gb. From looking at my logs it looks like logrotate has not run on syslog for 9 days. How can I tell why the syslog is not being rotated?
Thank you

It's not really designed for manual running.
How many compressed logs to you keep?

On syslog I have 7 compressed backups and 1 ncompressed backup. The first compressed backup was done 2/12/15 and and uncompressed backup was done 2/11/15. My syslog file has a new date/time stamp from about 10 minutes ago but is still showing 6 Gb and the records start at 2/11/15. I didn't do anything. Doesn't make sense to me. I did have the /var/log file open under computer at the time.
Thank you

From looking at the backups it looks like the syslog was being rotated every day before the 12th.
Thank you

Have you blacklisted the cause of those multitudinous errors?
Alternately, you could consider removing those error lines...

I am not seeing repeated error messages now. I looked at the last 100 lines with the tail command and the records looked normal. After I looked at the syslog records I checked the syslog properties and bot the modified and accessed time had been updated. The accessed time seems to get modified every time I look at it which is probably normal. Still showing 6Gb. I have not blacklisted anything. If I delete syslog does the system rebuild it? I could probably copy it over to my home directory and delete it from my log file.
Thank you
