Hello Marco,

can you please check the owner and groups of

/etc/openvswitch/ and

/var/run/openvswitch

and the files in these directories ?

Are there any hints if this issue might be related to

Bug 1909782 - /etc/openvswitch permissions broken after upgrade

?

Hi,

just a quick correction on the below -- 

the dependency chain is vdsmd --> vdsm-network --> openvswitch --> ovsdb-server (failed)

The conf.db file and /var/run/openvswitch dir are in 4.4.3 but not in 4.4.4

In 4.4.3 looks like the vdsm-network service does not depend from openvswitch:

*4.4.3* --

[Unit]
Description=Virtual Desktop Server Manager network restoration
Wants=network.target
Requires=libvirtd.service
After=libvirtd.service

*4.4.4* --

[Unit]
Description=Virtual Desktop Server Manager network restoration
Wants=network.target
Requires=libvirtd.service openvswitch.service NetworkManager.service
After=libvirtd.service openvswitch.service NetworkManager.service

Regards,
Marco

Hi all,

I have just upgraded one of my oVirt nodes from 4.4.3 to 4.4.4.

After the reboot, the 4.4.4 image is correctly loaded but vdsmd is not starting due to this error:

vdsmd.service: Job vdsmd.service/start failed with result 'dependency'.

Looks like it has a dependency on mom-vdsm, and this as well has a dependency issue:

mom-vdsm.service: Job mom-vdsm.service/start failed with result 'dependency'.

After some investigation looks like mom-vdsm has a dependency on ovsdb-server, and this is the unit creating the problem:

ovs-delete-transient-ports.service: Starting requested but asserts failed.

Assertion failed for Open vSwitch Delete Transient Ports

Failed to start Open vSwitch Database Unit.

Details below:

Any suggestions?

Hi,

the dependency on openvswitch comes from 4.4.4 this is correct. However I am not entirely sure why openvswitch would refuse to start.

Do you have some special OvS configuration in place on the affected host?

Thank you.

Regards,

Ales
