Invalid status on Data Center Default. Setting status to Non Responsive.
by Jelte Veldstra | Order2Cash 23 Feb '21

All,
We have built a new oVirt cluster from scratch. We used the 4.4.4 installer released in December 2020. When deploying the engine we had the wizard create a Gluster volume for the engine on three hosts. All went well and the cluster is starting to take shape.
When starting the engine we do see the following error each time the engine is started in /var/log/ovirt-engine/engine.log:
2021-02-23 08:06:09,208+01 WARN [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (EE-ManagedScheduledExecutorService-engineScheduledThreadPool-Thread-33) [4293beae] EVENT_ID: SYSTEM_CHANGE_STORAGE_POOL_STATUS_PROBLEMATIC(980), Invalid status on Data Center Default. Setting status to Non Responsive.
Also when navigating in the engine web-ui to Compute -> Data Centers -> Default and check the events an event of id 980 is shown with the message: “Invalid status on Data Center Default. Setting status to Non Responsive.”. The date/time matches when the error is shown in the engine log.
The datacenter overview does not show any warnings or errors and lists the Default datacenter as status Up. An interesting observation is that the cluster overview does have a status column on the far left, but the status is not mentioned. The field underneath the status heading is empty. Could that be the unknown status that the data center refers to?
How could we investigate this further? The storage volumes do not show any issues and the cluster seems to function okay (it has not been used a lot yet as it has been built yesterday/today), but the error message does sound like something we need to get out of the way before we put the actual workload on it.
Regards,
Jelte

Hi Joseph,
Somehow I missed your email.
I am thinking in similar direction, but in all honesty, it’s takes bit of effort to accept that we need complete platform deployment from 4.3 to 4.4, considering EL 8 is required, to have this fixed.
Anyway, let’s try re-deploying engine with current platform version in testing env, take our notes and share them. This is actually nice, team work. 😊
For now, in production, I am going to increase the RAM and CPU, and if reboot is required, just do it again.
Too many CI/CD deployment failures, to leave the engine process fighting for resources.

Hi Marko,
=A0I have also had this problem on an oVirt 4.3 install - I could never=20
fix it and have not tried to upgrade to 4.4 yet - my workaround for now=20
(as you have deduced) is to just 'up' it while running so its hotswapped=20
in - annoying, but I think the best way around this without upgrade=20
would be to re-deploy the hosted engine defining the new resources using=20
an engine-backup - but again this is just as scary as in-place upgrade=20
lest you lock yourself out from your other running VMs in a production=20
environment.
=A0I plan to do it - I just need some time to set it up in a lab so I=20
know what to expect.
Thanks,
Joe

Hi Marko,<br>
<br>
=A0I have also had this problem on an oVirt 4.3 install - I could
never fix it and have not tried to upgrade to 4.4 yet - my
workaround for now (as you have deduced) is to just 'up' it while
running so its hotswapped in - annoying, but I think the best way
around this without upgrade would be to re-deploy the hosted engine
defining the new resources using an engine-backup - but again this
is just as scary as in-place upgrade lest you lock yourself out from
your other running VMs in a production environment.<br>
<br>
=A0I plan to do it - I just need some time to set it up in a lab so I
know what to expect.<br>
<br>
Thanks,<br>
Joe<br>

There are different parameters around memory - are you sure you change
the correct one(s)?
Also adding Arik. Arik - please see the history of this thread. It
might be an issue in the engine, or in hosted-engine HA, or both - not
sure.
> But before I do that, we are currently on 4.3.8.2 version – is this by any change fixed by latest 4.3 version?
No idea. 4.3 is past EOL now. I suggest to try latest 4.4, and if it
reproduces, file a bug and attach all relevant logs (including engine,
vdsm, hosted-engine-ha).

Hi all,
Some spam was posted to the list a few minutes ago.
Sorry for that.
We are looking at preventing such cases in the future.
Best regards,

Hi Marko,
I have also had this problem on an oVirt 4.3 install - I could never
fix it and have not tried to upgrade to 4.4 yet - my workaround for now
(as you have deduced) is to just 'up' it while running so its hotswapped
in - annoying, but I think the best way around this without upgrade
would be to re-deploy the hosted engine defining the new resources using
an engine-backup - but again this is just as scary as in-place upgrade
lest you lock yourself out from your other running VMs in a production
environment.
I plan to do it - I just need some time to set it up in a lab so I
know what to expect.
Thanks,
Joe

But in UI, I still see
Defined Memory:
16384 MB
And the vm.conf on all three Hosts is still showing
smp=8 <= cpu increase is already updated
memSize=16384 <= but ram is still same
It looks like should report a bug. But before I do that, we are currently on 4.3.8.2 version – is this by any change fixed by latest 4.3 version?

Subject: Re: [ovirt-users] oVirt Engine increase RAM and CPU
Hi all,
Still testing in staging and I have not moved from updating RAM.
Initially, I made the change via Portal, updating defined memory of HE from 16384 to 32768. The change is instantly visible on VM when I execute free -m , but in the VM info it still says 16384.
I waited almost 4hours and this value did not get updated. Tried shutdown, remove GM, allow the HA to start the VM, it booted with 16384 allocated.
Than I did it again, and tried with Update OVF from storage domain where the HE disk is, same, no change.
Tried, updating memory again, migrating to another HA host – Update OVF , same thing, after reboot, the memory is back to 16384.
Can somebody give me an advice where to look further? Again, making the change in memory amount is instant on the VM, but after reboot, its back to 16384.

Hi All,
I have a server with a RAID1 disk for sda and RAID 5 disk for sdb.
Following default install, prior to Cockpit Gluster and Engine wizards there is only a single Volume Group which doesn’t allow me to continue.
If I manually configure the install and deselect sdb it gives other issues with multipath but at least I can resolve those.
Is there a specific kickstart confuguration that should be used?
Kind Regards
Shimme

up to 60 minutes :-).
I think you can change this with engine-config, item
OvfUpdateIntervalInMinutes .

oVirt 4.4.5 Sixth Release Candidate is now available for testing
The oVirt Project is pleased to announce the availability of oVirt 4.4.5
Sixth Release Candidate for testing, as of February 18th, 2021.
This update is the fifth in a series of stabilization updates to the 4.4
series.
How to prevent hosts entering emergency mode after upgrade from oVirt 4.4.1
Note: Upgrading from 4.4.2 GA or later should not require re-doing these
steps, if already performed while upgrading from 4.4.1 to 4.4.2 GA. These
are only required to be done once.
Due to Bug 1837864 <https://bugzilla.redhat.com/show_bug.cgi?id=1837864> -
Host enter emergency mode after upgrading to latest build
If you have your root file system on a multipath device on your hosts you
should be aware that after upgrading from 4.4.1 to 4.4.5 you may get your
host entering emergency mode.
In order to prevent this be sure to upgrade oVirt Engine first, then on
your hosts:
1.
Remove the current lvm filter while still on 4.4.1, or in emergency mode
(if rebooted).
2.
Reboot.
3.
Upgrade to 4.4.5 (redeploy in case of already being on 4.4.5).
4.
Run vdsm-tool config-lvm-filter to confirm there is a new filter in
place.
5.
Only if not using oVirt Node:
- run "dracut --force --add multipath” to rebuild initramfs with the
correct filter configuration
6.
Reboot.
Documentation
-
If you want to try oVirt as quickly as possible, follow the instructions
on the Download <https://ovirt.org/download/> page.
-
For complete installation, administration, and usage instructions, see
the oVirt Documentation <https://ovirt.org/documentation/>.
-
For upgrading from a previous version, see the oVirt Upgrade Guide
<https://ovirt.org/documentation/upgrade_guide/>.
-
For a general overview of oVirt, see About oVirt
<https://ovirt.org/community/about.html>.
Important notes before you try it
Please note this is a pre-release build.
The oVirt Project makes no guarantees as to its suitability or usefulness.
This pre-release must not be used in production.
Installation instructions
For installation instructions and additional information please refer to:
https://ovirt.org/documentation/
This release is available now on x86_64 architecture for:
* Red Hat Enterprise Linux 8.3 or newer
* CentOS Linux (or similar) 8.3 or newer
This release supports Hypervisor Hosts on x86_64 and ppc64le architectures
for:
* Red Hat Enterprise Linux 8.3 or newer
* CentOS Linux (or similar) 8.3 or newer
* oVirt Node 4.4 based on CentOS Linux 8.3 (available for x86_64 only)
See the release notes [1] for installation instructions and a list of new
features and bugs fixed.
Notes:
- oVirt Appliance is already available for CentOS Linux 8
- oVirt Node NG is already available for CentOS Linux 8
- We found a few issues while testing on CentOS Stream so we are still
