Hey folks,

We recently started getting alerts every time logrotate is run like this from a few host nodes:

error: vz-event:1 duplicate log entry for /var/log/vz-events.log


It appears that the disp-helper package has created two different logrotate configs for vz-events.log:

- /etc/logrotate.d/vz-event
- /etc/logrotate.d/collector

The contents of each are identical:

/var/log/vz-events.log {
        daily
        rotate 3
        size 100M
        delaycompress
        missingok
}


And according to yum whatprovides, both files are supposed to be there...


# yum whatprovides '*vz-event' 

disp-helper-1.0.19-2.vz7.x86_64 : Stat collector
Repo        : openvz-os
Matched from:
Filename    : /etc/logrotate.d/vz-event


# yum whatprovides '*logrotate.d/collector'

disp-helper-1.0.19-2.vz7.x86_64 : Stat collector
Repo        : openvz-os
Matched from:
Filename    : /etc/logrotate.d/collector


Is the vz-event file or the collector file the correct one going forward? Would like to remove the right one so updates don't create duplicates again in the future. (Both files have the same edited date).

Or perhaps devs need to update the disp-helper package to remove one of them?

Cheers

Compared the disp-helper package from 7.0.15 with the one in 7.0.16 release and it's clear that the logrotate config file 'collector' was the one that was added, whereas vz-event existed previously.

We're going to assume that collector is the one vz devs wanted there and vz-event was accidentally not removed when collector was added. This fixes it for each node:

[ -f /etc/logrotate.d/collector ] && rm -f /etc/logrotate.d/vz-event

Details here https://bugs.openvz.org/browse/OVZ-7266

Proper solution:

rpm -Uvh http://repo.virtuozzo.com/vzlinux/7/x86_64/os/Packages/d/disp-helper-1.0.19-3.vz7.x86_64.rpm
