Data Centers status Not Operational
by nexpron＠gmail.com
Hi everyone,
I found 3 servers (HV1, HV2, HV3) that contains VMs at another servers room. These servers are hosts based on KVM.
I logged into oVirt Engine Web Administration. Data Centers tab show me only one entry
Name: RCV
Storage: Shared
Status: Not Operational
Compability Version: 3.4
Description: [Empty]
Webbrowser oVirt Engine Web Administrator show me
oVirt Engine Version: 3.4.0-1.el6
One VM on HV3 has stopped, Hosts tab show Non Responsive Status for every host (HV1-3); every VM in Virtual Machines tab show Unknown status.
What do I'll do to change status in Data Center? How to start debug the reason? Last administrator leave documentation in vestigial form :)
DataCenter: RCV
-->Cluster: RCV_Cluster
---->Host: HV1 node
---->Host: Hv2 node
---->Host: HV3 engine
Best regards,

Please try with:
- appliance installed
- '--ansible-extra-vars=he_offline_deployment=true'
- latest released code (with your custom patch removed)
If it still fails, please open a bug and attach all relevant logs. Thanks!

How to handle broken NFS storage?
by David White
I'm trying to figure out how to keep a "broken" NFS mount point from causing the entire HCI cluster to crash.
HCI is working beautifully.
Last night, I finished adding some NFS storage to the cluster - this is storage that I don't necessarily need to be HA, and I was hoping to store some backups and less-important VMs on, since my Gluster (sssd) storage availability is pretty limited.
But as a test, after I got everything setup, I stopped the nfs-server.
This caused the entire cluster to go down, and several VMs - that are not stored on the NFS storage - went belly up.
Once I started the NFS server process again, HCI did what it was supposed to do, and was able to automatically recover.
My concern is that NFS is a single point of failure, and if VMs that don't even rely on that storage are affected if the NFS storage goes away, then I don't want anything to do with it.
On the other hand, I'm still struggling to come up with a good way to run on-site backups and snapshots without using up more gluster space on my (more expensive) sssd storage.
Is there any way to setup NFS storage for a Backup Domain - as well as a Data domain (for lesser important VMs) - such that, if the NFS server crashed, all of my non-NFS stuff would be unaffected?

Hosted-engine fail and host reboot
by Dominique D
I tried with a 1 baremetal host, 3 baremetals or virtual hosts and I still have the same problem for installing the hosted-engine. Hyperconverge installs well.
I have tried with multiple version of ovirt ISO file 4.4.1 and 4.4.4 and 4.4.6.
when I run hosted-engine --deploy or with the cockpit, it creates a temporary VM in the 192.168.222.x subnet and I am able to connect in ssh on this temporary ip. When the script displays "TASK [ovirt.ovirt.hoted_engine_setup]: Wait for the host to be up" the server reboots and I have nothing left.
problem when creation of the ovirtmgmt?

Adding a Ubuntu Host's NFS share to oVirt
by David White
Hello,
Is it possible to use Ubuntu to share an NFS export with oVirt?I'm trying to setup a Backup Domain for my environment.
I got to the point of actually adding the new Storage Domain.
When I click OK, I see the storage domain appear momentarily before disappearing, at which point I get a message about oVirt not being able to obtain a lock.
It appears I'm running into the issue described in this thread: https://lists.ovirt.org/archives/list/users@ovirt.org/thread/BNVX.... Although the actual export is ext4, not xfs.
From what I'm reading on that thread and elsewhere, it sounds like this problem is a result of SELinux not being present, is that correct?
Is my only option here to install an OS that supports SELinux?

by Strahil Nikolov
I think you can download and install the ovirt-engine-appliance rpm (the big one) from https://resources.ovirt.org/pub/ovirt-4.4/rpm/el8/x86_64/
in advance.

Hello,
I am trying to test oVirt node 4.4.6 inside my company’s network which needs proxy setting for internet access.
Is there any possibility to deploy host engine without any internet access? i.e. Is offline deployment of hosted engine possible?
I have added the following line at the end of the file /usr/share/ovirt-hosted-engine-setup/ansible/trigger_role.yml
environment:
https_proxy: "http://<proxy_host>:<proxy_port>"
http_proxy: "http://<proxy_host>:<proxy_port>"
But it gives error in the process of “hosted-engine --deploy”. I am not sure if this a typical issue in my company’s network but, it would be great if there is any offline installation method (without accessing internet repository).
I have also tried to use “hosted-engine --deploy --ansible-extra-vars=he_offline_deployment=true” but, it is not helping me at all.
With regards

Can't remove snapshot
by David Johnson
Hi all,
I patched one of my Windows VM's yesterday. I started by snapshotting the
VM, then applied the Windows update. Now that the patch has been tested, I
want to remove the snapshot. I get this message:
Error while executing action:
win-sql-2019:
- Cannot remove Snapshot. The following attached disks are in ILLEGAL
status: win-2019-tmpl_Disk1 - please remove them and try again.
Does anyone have any thoughts how to recover from this? I really don't want
to keep this snapshot hanging around.
Thanks in advance,
*David Johnson*
