logrotate fails on LXC

[Marco Bertorello]

daily, I receive this alert from logrotate script in cron.daily:

/etc/cron.daily/logrotate:
Failed to kill unit rsyslog.service: Input/output error
error: error running non-shared postrotate script for /var/log/syslog of '/var/log/syslog
'
run-parts: /etc/cron.daily/logrotate exited with return code 1

My ubuntu is a LXC running on top of ProxmoxVE.

the problem occour when logrotate script call /usr/lib/rsyslog/rsyslog-rotate that has this call:

systemctl kill -s HUP rsyslog.service

I already checked my disks status (because the input/output error) but them are ok.

The same issue is present also in another LXC, ubuntu also this one, running on another node of the same cluster

I have met same case with you also I'm using proxmox. Should like the image of Proxmox provided for us diffent a bit with normal OS. My laptop using Ubuntu 18.04 but no problem with the rsyslog. It still is version rsyslogd 8.32.0.

Rsyslog is included in all major distributions. So you do not necessarily need to take care of where packages can be found - they are “just there”. Unfortunately, the distros provide often rather old versions. This is especially the case for so-called enterprise distributions.

So to fix this, I have still newest version of rsyslog then the issue has solved.

sudo apt-get install -y software-properties-common # Provide add-apt-repository
sudo add-apt-repository ppa:adiscon/v8-stable
sudo apt-get update
sudo apt-get install rsyslog

Let's run again:
# /etc/cron.daily/logrotate

Hi Phan,

I checked my setup,

on the proxmox machine rsyslog is old: 8.24.0-1 (same version than
debian stretch).

on the guest, rsyslog is up to date: 8.32.0-1ubuntu4 (bionic)

Do you mean I have to upgrade rsyslog on the host (proxmox)?

In this case, this should be a proxmox's bug, right?

Thanks alot and best regards

Hi Marco,

In my opinion, I think we should install rsyslog above on the container. You could create a new image for ubuntu 18.04 for never do it again.

Like what I said, could be it happened on the image of Proxmox, so you should install the newest package of rsyslog on the container.

By default, Ubuntu 18.04 rsyslogd version is rsyslogd 8.32.0.

This is a result after upgrade:

$ rsyslogd -version
rsyslogd 8.40.0, compiled with:
 PLATFORM: x86_64-pc-linux-gnu
 PLATFORM (lsb_release -d):
 FEATURE_REGEXP: Yes
 GSSAPI Kerberos 5 support: No
 FEATURE_DEBUG (debug build, slow code): No
 32bit Atomic operations supported: Yes
 64bit Atomic operations supported: Yes
 memory allocator: system default
 Runtime Instrumentation (slow code): No
 uuid support: Yes
 systemd support: Yes
 Number of Bits in RainerScript integers: 64
