Docker storage issues on FC24 nodes
-----------------------------------
Key: OVIRT-1421
URL: https://ovirt-jira.atlassian.net/browse/OVIRT-1421
Project: oVirt - virtualization made easy
Issue Type: Bug
Components: oVirt CI
Reporter: Barak Korren
Assignee: Evgheni Dereveanchin
Priority: High
Labels: containers
docekr startup seems to be failing on FC24 nodes and making other dokcer commands get stuck forever.
The core reason behind the failure seems to be that the Docker storage setup failed:
{code}
[root@vm0064 ~]# systemctl status docker-storage-setup

This seem to be does to the fact that the system's root filesystem is on a plain disk rather then LVM. This is although the docker default DM storage driver is supposed to be able to use a plaing file on the filesystem. Need to check if this is an issue specific to this slave of something that has to do with all FC24 slaves.
