This is my logrotate config:

/var/log/glusterfs/*.log /var/log/glusterfs/bricks/*.log /var/log/glusterfs/bricks/*.log.* {
  rotate 3
  size 100M
  /usr/bin/killall -HUP glusterfs > /dev/null 2>&1 || true
  /usr/bin/killall -HUP glusterd > /dev/null 2>&1 || true

This is the directory:

username@server:/var/log/glusterfs/bricks$ ll
total 405980
-rw------- 1 root root         0 Dec 23 00:05 be-data.log

What I can see:

  • Logs are not compressed
  • Logs are larger than 100MB
  • Count does not work
  • Empty log files are present, I do not want empty log files which are rotated

How should my config of logrotate be to solve all the issues described above?

In the configuration file, you have specified two patterns for the log files in the /var/log/glusterfs/bricks directory:

  1. *.log
  2. *.log.*

The second of these patterns will match any rotated log file. This is why you get files with seemingly endless .1 suffixes.

The logfiles are not compressed because you have delaycompress in the configuration. They will be compressed on the next rotation. Note that the first problem (rotation of already rotated logs due to the second pattern above) effectively disables any compression since all rotations are "the first" rotation.

The logfiles are rotated if they are larger than 100M, as per your configuration. There is one file larger than this. It's being rotated at every invocation and never compressed, due to the aforementioned problem with the second logfile pattern above.

There are empty logfiles. This is simply yet another effect of the faulty logfile matching pattern above. When a logfile is rotated, it's copied to name-of-file.log.1 and the original file, name-of-file.log, is truncated ("emptied"). Again, because of the *.log.* pattern in the configuration, the file name-of-file.log.1 will be copied to name-of-file.log.1.1 upon the next rotation, and the original name-of-file.log.1 will be truncated.

It's all working, but since the logfile pattern picks up not only the actual logfiles but the rotated logfiles as well, you end up with this mess.

  • Ah, thought it should be there. Guess it doesn't.

Viewing manpage of logrotate is free during this week!

          Postpone compression of the previous log file to the next  rota‐
          tion  cycle.  This only has effect when used in combination with
          compress.  It can be used when some program cannot  be  told  to
          close  its logfile and thus might continue writing to the previ‐
          ous log file for some time.

   size size
          Log  files are rotated only if they grow bigger then size bytes.
          If size is followed by k, the size is assumed  to  be  in  kilo‐
          bytes.   If the M is used, the size is in megabytes, and if G is
          used, the size is in gigabytes. So size  100,  size  100k,  size
          100M and size 100G are all valid.

          Rotate  the  log  file  even  if  it  is  empty,  overriding the
          notifempty option (ifempty is the default).
