Duplicate logrotate entries if ceph-base and ceph-common are installed (Ubuntu 16.04)
#1 Updated by Burkhard Linke almost 2 years ago
(fingers were too fast...)
Colocating rados gateway and osd on the same host, ceph-common and ceph-base are installed as dependencies.
ceph-common installed /etc/logrotate.d/ceph-common, ceph-base contains /etc/logrotate.d/ceph.logrotate. Both target "/var/log/ceph/*.log", which breaks logrotate since the same files are targeted by multiple entries.
- provide specific logrotate entries with specific packages (e.g. /var/log/ceph/ceph-osd* in ceph-osd package)
- move log rotation to own package
Ceph version: 10.2.7-1xenial
OS: Ubuntu 16.04.2

why do you think ceph-common installed /etc/logrotate.d/ceph-common? is it possible that it was installed by previous installation? and from where/how exactly did you download these package?
#4 Updated by Burkhard Linke almost 2 years ago
The files are reported as belonging to the ceph-base and ceph-common packages:
root@ceph-storage-02:/var/lib/dpkg/info# fgrep logrotate *.list | grep ceph
I use the european ceph mirror:root@ceph-storage-02:~# cat /etc/apt/sources.list.d/ceph.list
- This file is managed by Puppet. DO NOT EDIT.
deb http://eu.ceph.com/debian-jewel/ xenial main
The host was built from scratch, so there was no previous installation of other ceph packages (neither other version nor other origin). Installation was done using some custom puppet module based on puppet's apt source management and its package management.

i am confused. Burkhard, could you post the output of
dpkg -s ceph-common
my wild guess is that you are using a downstream package.

And I am confused, too.
- dpkg -s ceph-common

Description: common utilities to mount and interact with a ceph storage cluster
Ceph is a massively scalable, open-source, distributed
storage system that runs on commodity hardware and delivers object,
block and file system storage. This is a collection
of common tools that allow one to interact with and administer a Ceph cluster.
It seems that during host provisioning the distribution package was installed, which contains the rogue logrotate file. The ceph provided packages are fine. The logrotate file is even recognized as being obsolete, but not automatically removed during package upgrade. This is only done if the former package is purged.
I'm not sure what's the right way to handle this (and whether this problem happens often). According to https://raphaelhertzog.com/2010/10/07/the-right-way-to-remove-an-obsolete-conffile-in-a-debian-package/ , a package might be able to remove obsolete conffiles in package postprocessing scripts, but the information is from 2010.
