This message is a reminder that Fedora 25 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 25. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora 'version'
of '25'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 25 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.

Still a problem with Fedora 27.

I do not use a docker container so i can't reproduce it.
And i don't see the log messages in a normal MATE installation.

you can try it by installing docker and run a container,

dnf install docker
systemctl start docker
docker pull docker.io/alpine
docker run -it --rm docker.io/alpine /bin/bash

and look at the logs in journalctl

I only want to reproduce it, ...not to learn to use or debug docker :-)

[root@mother rave]# docker run -it --rm docker.io/alpine /bin/bash
/usr/bin/docker-current: Error response from daemon: oci runtime error: container_linux.go:247: starting container process caused "exec: \"/bin/bash\": stat /bin/bash: no such file or directory".
[root@mother rave]# docker run -it --rm docker.io/alpine /bin/bash
/usr/bin/docker-current: Error response from daemon: oci runtime error: container_linux.go:247: starting container process caused "exec: \"/bin/bash\": stat /bin/bash: no such file or directory".

my bad alpine don't come with bash, use `sh` instead

# docker run --name test -it --rm docker.io/alpine /bin/sh

you can then stop it with

# docker kill test

Ok,
that works, but i dond see the mentioned warnings in journal...
See my logs.
If i fire up mate-system-monitor from context-menu of monitor applet i get only this one.

Nov 18 19:56:14 mother.mother.loc mate-system-mon[9514]: SELinux was found but is not enabled.

Have you ever tried to disable selinux?

My problem is with "System Monitor" applet when enabling disk activity monitoring
see the linked video on youtube - https://youtu.be/oRWeKEIhNx8

I tried hard but i don't get the warnings when enabling disk activity monitoring in the applet, see my video from f27.
https://www.dropbox.com/s/vy6bv30zesd0u5u/docker-with%20system-monitor-applet.ogv?dl=0
Do i miss something?

Selinux is disabled in this installation too.

Yea the steps to produce are the same, but it seems like something is different between our systems.

can you please output you lvs output ?

Also , I run SELinux in permissive mode.
and i have the same package version as you.

Hmm, i don't use LVM, i use normal storages and of course fdisk -l
don't show me any docker-pool as it isn't set.

[root@mother rave]# cat /etc/sysconfig/docker-storage-setup
# Edit this file to override any configuration options specified in

# Do not edit. This file is auto-generated by docker-storage-setup.

Well i can create a small partition somewhere for testing, but i don't want to learn how to use docker at the moment ;-)

# A quoted, space-separated list of devices to be used. This currently
# expects the devices to be unpartitioned drives. If "VG" is not specified,
# then use of the root disk's extra space is implied.
#
# DEVS=/dev/vdb

Sorry, this sounds like i need to have a extra hard disk and it isn't possible to use an single partition.

you can probably use a USB stick for the test ?

ok, can you give working and tested instructions to add a usb-stick as docker image please?

first let me thank you for agreeing to go over all this steps just to fix this problem.

First stop docker daemon if it is running
# systemctl stop docker

then delete (or move) docker metadata/image folder
# mv /var/lib/docker /var/lib/docker.backup

remove the current config file for docker storage
# rm /etc/sysconfig/docker-storage

next format a usb disk to use lvm (e.g my usb stick is /dev/sdd)

# export USB_STICK=/dev/sdd
# pvcreate $USB_STICK
# vgcreate vg_docker $USB_STICK

now if you type `vgs` you will see that you have a new VolumeGroup named `vg_docker`
# vgs

  VG #PV #LV #SN Attr VSize VFree
  vg_docker 1 1 0 wz--n- 7.45g 4.47g

change the config file `/etc/sysconfig/docker-storage-setup`
and set the variable VG to be the name of the volumegroup we just created.
e.g:
# cat /etc/sysconfig/docker-storage-setup
VG=vg_docker

run the docker storage setup script, which create /etc/sysconfig/docker-storage
# /usr/bin/container-storage-setup

now you can start docker again, and pull a new image

# docker pull alpine
Using default tag: latest
Trying to pull repository registry.fedoraproject.org/alpine ...
Trying to pull repository registry.access.redhat.com/alpine ...
Trying to pull repository docker.io/library/alpine ...

Status: Downloaded newer image for docker.io/alpine:latest

run the container
# docker run -it --rm --name alpine alpine /bin/sh

and now watch the journald logs, while enabling the disk monitoring

Thanks, for this guide and i can reproduce it now.
