Import Ge0-Replicated Storage Domain fails
by simon＠justconnect.ie
Hi All,
I have 2 independent Hyperconverged Sites/Data Centers.
Site A has a GlusterFS Replica 3 + Arbiter Volume that is Storage Domain data2
This Volume is Geo-Replicated to a Replica 3 + Arbiter Volume at Site B called data2_bdt
I have simulated a DR event and now want to import the Ge0-Replicated volume data2_bdt as a Storage Domain on Site B. Once imported I need to import the VMs on this volume to run in Site B.
The Geo-Replication now works perfectly (thanks Strahil) but I haven't been able to import the Storage Domain.
Please can someone point me in the right direction or documentation on how this can be achieved.
Kind Regards
Shimme...

importing vm's from storage pool from 4.1.6.2-1 in to 4.4.6 fails due to lingering snapshot configuration in source
by Charles Kozler
I know the subject is a bit wordy but let me try to explain
I have a 4.1 installation that I am migrating to 4.4. I placed the storage
domain into maintenance and then rsync'ed it to the storage I am using for
4.4. In 4.4 I import the domain and it comes in fine, however, when trying
to import some VM's it fails because it says it cannot find a disk. The
disk ID's I cannot find anywhere in 4.1 or 4.4 so I opened OVF_STORE after
upgrading the pool in 4.4 and look at the ovf file for some of the VM's
that are failing to import
I see this in the ovf configuration file -
<Section xsi:type="ovf:SnapshotsSection_Type">
<Snapshot ovf:id="e300fa3b-eee4-4b96-9103-45115081db57">
<Type>ACTIVE</Type>
<Description>Active VM</Description>
<CreationDate>2019/12/19 16:47:48</CreationDate>
<Memory>07d3447c-c640-4163-9cf1-74ce126d702a,59b5cfdf-015b-0333-004b-000000000397,8c48ea33-dc34-403a-90d2-a3e78776404c,1757809b-9685-4315-a92e-3ea82dc6d8a8,94a2c2b3-e02e-4b05-80eb-6f4b7a9701e7,248a9fd1-61f0-4c5a-b6ab-4630d433c6fa</Memory>
</Snapshot>
</Section>
</Content>
</ovf:Envelope>
These are the disk ID's I can see failing to import in engine.log
I am aware that importing a VM cannot support snapshots and have found
multiple mailing list posts around this, however, I do not have any
snapshots visible in 4.1 UI.
I also tried modifying OVF_STORE by untar'ing it and editing the ovf files
directly, however, this does not work as it ends up overwritten by ovirt
with the previous configuration
Any ideas? As noted, I cannot see any snapshots listed in 4.1 source pool
so I therefore cannot remove this stale configuration from the source and
upon importing in to 4.4 it fails because it cannot find the disks
I tried import partial and that still fails which to me seems like a bug
because the idea of the import partial is to still register the VM even if
it cant find disks
I also tried scanning domain for disks and update OVF's in the UI and it
does not help anything

Grafana oVirt 4.4.4 Node install - Grafana Monitoring Portal not available
by simon＠justconnect.ie
Having installed oVirt 4.4.4 HCI 3 node cluster, the Grafana 'Monitoring Portal' was not visible on the Default page.
It appears that Grafana is installed but not configured.
I have checked a 4.4.3 environment and it is installed and running, so is this a bug with 4.4.4.7-1.el8?
Any help would be appreciated.

Replacing hosted engine on Gluster
by Chris Adams
I've run oVirt on iSCSI storage for years, and I've had to replace the
hosted engine a couple of times (upgrade from CentOS 6 to 7, then moving
to new storage).
I'm looking at oVirt on hyperconverged Gluster storage. I see pages
about how to replace a host, but how do you replace the engine when
needed? Is it possible to connect a new hosted engine to the existing
Gluster storage?
I'm just trying to understand all the differences of iSCSI vs. Gluster
before deploying it for real; if there's info online that I missed, feel
free to point me to it.
Thanks!

Operation canceled: CA not found.
by jesado74＠gmail.com
Hello; when I try to enter the graphical console to a vm I get the following message:
Operation canceled: CA not found.
Change the certificates as the procedure says https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.1/...
And all services: ovirt-engine.service / ovirt-websocket-proxy / ovirt-imagenio-proxy.service / ovirt-provider-ovn.service - are working properly.
But there is something wrong.
This has happened to someone else when changing the certificates from the ovirt engine to a third-party CA certificate.
Thanks.

Recovering from corrupted hosted-engine
by timothy.dilbert＠bmt.ky
Hi Guys,
We had a 2-node self-supported RHEV cluster that we used for our development environment. We're in the middle of a migration from RHEV over to VMware - one host has already been converted to VMware and we have actively been running VM migrations over to VMware. During the migration, we had an extended power outage and had to improperly shut down the RHEV host. Since bringing it back up we've not been able to start the hosted-engine. Each time we try to start the hosted engine we're getting the following messages:
## START
[root@bmrhev01 ~]# hosted-engine --vm-start
VM exists and is down, cleaning up and restarting
VM in WaitForLaunch
[root@bmrhev01 ~]# hosted-engine --vm-status

conf_on_shared_storage=True
maintenance=False
state=EngineStarting
stopped=False
END ##
We've tried rebooting a number of times. Restarting various oVirt services. Nothing appears to be resolving the issue. At this point, the only thing I truly care about is migrating the guest VMs over to VMware. There's nothing else in the RHEV environment I care about. I'm happy to settle with any of the following, providing they can salvage the guest VMs:
a) Deleting and redeploying the hosted-engine.
b) Abandoning the hosted-engine and some how converting the guest VMs over to VMware.
I don't have enough experience to know if any of the above is possible or the repercussions of either of them. Any help from anyone would be very helpful. I'm sorry to be a leach, rather than a contributor. I'm seriously in trouble here and a kind heart would be much appreciated.
Thanks, Tim.
