Hey Ovirt Users and Team,
I have a host that I am unable to recover post a network outage. The host =
is stuck in unresponsive mode, even though the host is on the network, able=
to SSH and seems to be healthy. I=1B$B!G=1B(Bve tried several things to r=
ecover the host in Ovirt, but have had no success so far. I=1B$B!G=1B(Bd l=
ike to reach out to the community before blowing away and rebuilding the ho=
st.
Environment: I have an Ovengine server with about 26 Datacenters, with 2 to=
3 hosts per Datacenter. My Ovengine server is hosted centrally, with my h=
osts being bare-metal and distributed throughout my environment. Ovengin=
e is version 4.0.6.
What I=1B$B!G=1B(Bve tried: put into maintenance mode, rebooted the host. =
Confirmed host was rebooted and tried to active, goes back to unresponsive.=
Attempted a reinstall, which fails.
Checking from the host perspective, I can see the following problems:
[boxname~]# systemctl status vdsmd
=1B$B!|=1B(B vdsmd.service - Virtual Desktop Server Manager
Loaded: loaded (/usr/lib/systemd/system/vdsmd.service; enabled; vendor p=

erver Manager.

Going a bit deeper, the results of journalctl -xe:

Does the community have suggestions on what can be done next to recover thi=
s host within Ovirt? I can provide additional log dumps as needed, please =
inform with what you need to assist further.
Thank you,
Tony
