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 ● docker-storage-setup.service - Docker Storage Setup Loaded: loaded (/usr/lib/systemd/system/docker-storage-setup.service; disabled; vendor preset: disabled) Active: failed (Result: exit-code) since Tue 2017-05-30 03:14:49 UTC; 1 day 2h ago Process: 1489 ExecStart=/usr/bin/docker-storage-setup (code=exited, status=1/FAILURE) Main PID: 1489 (code=exited, status=1/FAILURE) May 30 03:14:49 vm0064.workers-phx.ovirt.org systemd[1]: Starting Docker Storage Setup... May 30 03:14:49 vm0064.workers-phx.ovirt.org docker-storage-setup[1489]: INFO: Volume group backing root filesystem could not be determined May 30 03:14:49 vm0064.workers-phx.ovirt.org docker-storage-setup[1489]: ERROR: No valid volume group found. Exiting. May 30 03:14:49 vm0064.workers-phx.ovirt.org systemd[1]: docker-storage-setup.service: Main process exited, code=exited, status=1/FAILURE May 30 03:14:49 vm0064.workers-phx.ovirt.org systemd[1]: Failed to start Docker Storage Setup. May 30 03:14:49 vm0064.workers-phx.ovirt.org systemd[1]: docker-storage-setup.service: Unit entered failed state. May 30 03:14:49 vm0064.workers-phx.ovirt.org systemd[1]: docker-storage-setup.service: Failed with result 'exit-code'. {code} 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.
