CC7 logrotate cron job is too noisy (sends mail)

[jmuf]

on Centos7, the supplied logrotate entry causes a mail to be sent:

spawn/bin/sh -c echo ping > /var/log/xrootd/fed/.xrootd.log

Comes straight from the RPM:

[root@xrdcmsglobal01 ~]# rpm -qf /etc/logrotate.d/xrootd
xrootd-server-4.1.1-1.el7.x86_64
[root@xrdcmsglobal01 ~]# rpm -Vvf /etc/logrotate.d/xrootd | grep /etc/logrotate.d/xrootd
......... c /etc/logrotate.d/xrootd

(whatever this "ping" does).

The ping causes xrootd/cmsd to close and reopen the log file, creating it if necessary. One would normally use a signal (e.g. SIGHUP) and that is all well and fine except for daemons that can be outfitted with custom plugins. We have found that some plugins use signals for other things and using them for log file rotation conflicts with those plugins leading to all sorts of other problems. So, the safest way to do this is via a dedicated pipe. A message appearing on the pipe means close/open the log file.

I am not sure I can do anything about it. Is there a way you can configure logrotate on your side not to echo the postrotate scriptlets?

As discussed, I will silence the output from expect.
