I've specific problem with logrotate which is rotating before reaches the limit - set by maxsize

logrotate version - 3.8.6

I've a custom logrotate file

    rotate 40
    maxsize 200M

and logrotate is set in crontab without -f and rotate logs almost every hour despite it did not reach the maxsize listed below (logs are rotated with few MBs):

 87250 Sep  8 19:30 access_log.2020-09-08_19.gz


8632827 Sep  9 12:56 access_log

The output:

empty log files are rotated, log files >= 209715200 are rotated earlier, old logs are removed
considering log /var/web/log/access_log
  log needs rotating

... Sep  9 13:00 access_log.2020-09-09_13.gz

Can sb tell me what is wrong? Why are logs rotated before size limit? Thanks

  • did you reload logrotate or cron service?

  • Of course, before I started mess up with max size I had one log per day (daily rotation...) Now as you can see, logs are rotated more frequently, which confirms logrotate reload... Also I've updated cron service to commit every 30 minutes

  • Deb/Ubuntu do have a maxsize, so the accepted answer is wrong. Your problem is caused by an interaction of the settings of the cron period, and whatever you specified as the rotate period in your config file.

In the logrotate manual page there is no "maxsize" option, just "size" and "minsize".

From https://linux.die.net/man/8/logrotate

If you change "maxsize" to "size" I'm sure it will work!
