oVirt4.1 add host error. can i upgrade from 4.1 to 4.4? without updating sequentially 4.1-4.2-4.3-4.4
by grig.4n＠gmail.com
HI!
There is an oVirt 4.1 self-hosted engine cluster of two hosts and a storage connected via iscsi. When trying to add another host, it gives an error: "ERROR otopi.context context._executeMethod:151 Failed to execute stage 'Setup validation': Cannot locate vdsm package, possible cause is incorrect channels". Older hosts on Centos 7.5.1804, last on Centos 7.9.2009. Is it possible to go from 4.1 to 4.4 using the third host as the main one for the transfer?

Cant add vm network with vlan to bonded interface
by murat.celebi＠dbpro.com.tr
Hello,
I am new to ovirt and try to migrate my companies vmware infra to ovirt. The Engine setup went fine without any problems.
These are the steps which I am doing and having problems.
1. Prepare the KVM host by installing the RPM's.
2. Add the kvm host to the engine. Everything is working fine at this point.
3. I am creating a new Network for vm usage named VLAN10. And I am tagging the network with vlan id 10.
4. I am bonding two 25Gb/s interface's with balance-xor mode with the name bond1.
5. When I add the network VLAN10 to the bond1 interface I cant see the logical network assigned to the bond. After this step I am not able to delete the bond since I am getting errors when I try to delete the bond.
Any help would be greatly appreciated.
Thank you

Re: oVirt Engine increase RAM and CPU
by Strahil Nikolov
I think that I got such case before (4.2) and the only way I managed to update the HE VM was to set the OVF update interval to 1 min and wait for an hour to pass.

Right Glusterfs Config on HA Server
by Marcel d'Heureuse
Hi Guys or Girls,
I have a problem in a productive system. We use three Servers which have
a Raid 5 with four Harddrives SATA 8 TB 7200 rpms. The Systems are
interconnected for glusterfs with 1 GB/s.
The Network Load between all three servers are between 5 and 8 % of the
network. The Glusterfs has a separate VLAN which compltete isolated from
other networks.
Find attached a small drawing.
On that server we rum as HA and there are 8 VMs installed. Most of the
VMs working well but if there is high load on the system some of the VM
can't write the Data in a "good" speed on the disks. The Glusterfs is
configured as Replica on the Raid5 disk which is as Jbob in Glusterfs
defiend.
If i take a look on the iostats i can see that the Harddisk have round
50 open connections some of the glusterfs and a lot of the vms. In side
the VMs i can see long iowaiting times from 300 up to 600 ms. With is on
case of a Posgresql database very long.
Should we configure the Raid5 controller out that the controller only
should 4 disks with 8 TB and Glusterfs should connect directly to the
/dev/sd[b-e]?
What do you think? Will SSD HDD will help on performance but the same
config with Raid5 and Jbod could be the bigger problem.
Thanks

oVirt Node install with Foreman VG issue
by simon＠justconnect.ie
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

Re: oVirt Node install with Foreman VG issue
by Simon Scott
Thanks Strahil,
Unfortunately changing the filter is done after the initial install.
We manually partition sda so that sdb isn’t touched during install.
The issues with multipath grabbing sdb are ongoing with a possible manual fix being tested now.
Testing has paused at the moment as we have lost gluster on the arbiter node as per https://lists.ovirt.org/archives/list/users@ovirt.org/thread/U64MGWSUCFJR... which looks like a full oVirt rebuild again.
Any help on that thread would be appreciated.
Thanks again
Shimme

Most probably there is an LVM filter.
As stated in the /etc/multipath.conf , use a special file to blacklist the local disks without modifying /etc/multipath.conf

Reinstalled Host 4.4.4 bricks failing to start
by simon＠justconnect.ie
3 Node HCI - Local Storage Replica 2+1
After changing the Cluster 'Default Network Provider' from ovirt-provider-ovn to 'No Default Provider' notification (as expected) to reinstall was flagged against each host.
Host 3 (Arbiter) was reinstalled but failed to Activate due to Gluster Bricks not starting. No GlusterFS process for the bricks is listed when checking Status of glusterd.
Please can someone help to identify the issue and resolution.
Attempted further reinstallation of the Host fails.
Kind Regards

oVirt fails to update OVF
by Jürgen Walch
Hi everybody,
we are running an oVirt 4.3.10 production cluster with 9 hosts and 5 datastore domains.
Since yesterday we get error messages
26.02.2021 02:00:48 VDSM command SetVolumeDescriptionVDS failed: Could not acquire resource. Probably resource factory threw an exception.: ()
26.02.2021 02:00:48 Failed to update OVF disks 5aa438e3-8d22-4b6c-bccf-a843151ca0be, OVF data isn't updated on those OVF stores (Data Center datacenter01, Storage Domain vmstore13).
26.02.2021 02:00:48 Failed to update VMs/Templates OVF data for Storage Domain vmstore13 in Data Center datacenter01.
every hour.
Only one domain (vmstore13) is affected, this domain is (like 3 others in the cluster) based on glusterfs.
Trying to update the OVF's manually from the engine web-gui leads to the same result followed by (a misleading)
26.02.2021 02:00:49 OVF_STORE for domain vmstore13 was updated by admin@internal-authz.
The vm's with discs on the affected domain are running fine, snapshots are working.
So far I have tried to move the SPM role to another host. This succeeded, but the error messages persist.
The vdsm log on the SPM host contains something like
2021-02-26 03:00:57,701+0100 INFO (jsonrpc/2) [vdsm.api] START setVolumeDescription(sdUUID=u'9f731135-f5d9-4609-9e3b-fa9cae75e314', spUUID=u'33e8dc9e-8bc8-11ea-bd76-00163e741033', imgUUID=u'5aa438e3-8d22-4b6c-bccf-a843151ca0be', volUUID=u'0795e58c-4960-413a-a0b4-e8a6d547fda5', description=u'{"Updated":false,"Last Updated":"Wed Feb 24 17:48:17 CET 2021","Storage Domains":[{"uuid":"9f731135-f5d9-4609-9e3b-fa9cae75e314"}],"Disk Description":"OVF_STORE"}', options=None) from=::ffff:10.70.1.1,46968, flow_id=1f314676, task_id=9101db01-b4f0-447e-a5a9-b6af76278d55 (api:48)

for each error, I have attached the relevant part of vdsm.log.
Has anyone experienced this behaviour before and can provide help ?

oVirt 4.2 cluster upgrade
by Fedele Stabile
I have a 3 node oVirt 4.2.1 cluster,
i'm using a self-hosted engine architecture and
storage-engine is on a glusterfs replica 3
of the cluster.
The oldest CPU is SandyBridge family (E5-2609)
and incidentally I have connectivity problems with IPMI NIC of one node,
but Hosted Engine HA is enabled and working.
Is it safe to upgrade to the last oVirt 4.4 without a down of vm running on the cluster?
May I just click on the button
Upgrade
that appears on the host page?
