Re: Single instance scaleup.

Hi Leo,
As you do not have a distributed volume , you can easily switch to replica 2 arbiter 1 or replica 3 volumes.
You can use the following for adding the bricks:

Failed to add storage domain
by thunderlight1＠gmail.com
Hi!
I have installed oVirt using the iso ovirt-node-ng-installer-4.3.2-2019031908.el7. I the did run the Host-engine deployment through Cockpit.
I got an error when it tries to create the domain storage. It sucessfully mounted the NFS-share on the host. Bellow is the error I got:

How to connect to a guest with vGPU ?
by Josep Manel Andrés Moscardó
Hi,
I got vGPU through mdev working but I am wondering how I would connect
to the client and make use of the GPU. So far I try to access the
console through SPICE and at some point in the boot process it switches
to GPU and I cannot see anything else.
Thanks.

Vm suddenly paused with error "vm has paused due to unknown storage error"
by Jasper Siero
Hi all,
Since we upgraded our Ovirt nodes to CentOS 7 a vm (not a specific one but never more then one) will sometimes pause suddenly with the error "VM ... has paused due to unknown storage error". It happens now two times in a month.
The Ovirt node uses san storage for the vm's running on it. When a specific vm is pausing with an error the other vm's keeps running without problems.
The vm runs without problems after unpausing it.

CentOS Linux release 7.1.1503

Ovirt-engine-ha cannot to see live status of Hosted Engine
by asm＠pioner.kz
Good day for all.
I have some issues with Ovirt 4.2.6. But now the main this of it:
I have two Centos 7 Nodes with same config and last Ovirt 4.2.6 with Hostedengine with disk on NFS storage.
Also some of virtual machines working good.
But, when HostedEngine running on one node (srv02.local) everything is fine.
After migrating to another node (srv00.local), i see that agent cannot to check livelinness of HostedEngine. After few minutes HostedEngine going to reboot and after some time i see some situation. After migration to another node (srv00.local) all looks OK.

As we can see, agent thinking that HostedEngine just in powering up mode. I cannot to do anythink with it. I allready reinstalled many times srv00 node without success.
One time i even has to uninstall ovirt* and vdsm* software. Also here one interesting point, after installing just "yum install http://resources.ovirt.org/pub/yum-repo/ovirt-release42.rpm" on this node i try to install this node from engine web interface with "Deploy" action. But, installation was unsuccesfull, before i didnt install ovirt-hosted-engine-ha on this node. I dont see in documentation that its need bofore installation of new hosts. But this is for information and checking. After installing ovirt-hosted-engine-ha node was installed with HostedEngine support. But the main issue not changed.
Thanks in advance for help.

Hyperconverged setup - storage architecture - scaling
by Leo David
Hello Everyone,
Reading through the document:
"Red Hat Hyperconverged Infrastructure for Virtualization 1.5
Automating RHHI for Virtualization deployment"
Regarding storage scaling, i see the following statements:
*2.7. SCALINGRed Hat Hyperconverged Infrastructure for Virtualization is
supported for one node, and for clusters of 3, 6, 9, and 12 nodes.The
initial deployment is either 1 or 3 nodes.There are two supported methods
of horizontally scaling Red Hat Hyperconverged Infrastructure for
Virtualization:*
*1 Add new hyperconverged nodes to the cluster, in sets of three, up to the
maximum of 12 hyperconverged nodes.*
*2 Create new Gluster volumes using new disks on existing hyperconverged
nodes.You cannot create a volume that spans more than 3 nodes, or expand an
existing volume so that it spans across more than 3 nodes at a time*
*2.9.1. Prerequisites for geo-replicationBe aware of the following
requirements and limitations when configuring geo-replication:One
geo-replicated volume onlyRed Hat Hyperconverged Infrastructure for
Virtualization (RHHI for Virtualization) supports only one geo-replicated
volume. Red Hat recommends backing up the volume that stores the data of
your virtual machines, as this is usually contains the most valuable data.*
------
Also in oVirtEngine UI, when I add a brick to an existing volume i get the
following warning:
*"Expanding gluster volume in a hyper-converged setup is not recommended as
it could lead to degraded performance. To expand storage for cluster, it is
advised to add additional gluster volumes." *
Those things are raising a couple of questions that maybe for some for you
guys are easy to answer, but for me it creates a bit of confusion...
I am also referring to RedHat product documentation, because I treat
oVirt as production-ready as RHHI is.
*1*. Is there any reason for not going to distributed-replicated volumes (
ie: spread one volume across 6,9, or 12 nodes ) ?
- ie: is recomanded that in a 9 nodes scenario I should have 3 separated
volumes, but how should I deal with the folowing question
*2.* If only one geo-replicated volume can be configured, how should I
deal with 2nd and 3rd volume replication for disaster recovery
*3.* If the limit of hosts per datacenter is 250, then (in theory ) the
recomended way in reaching this treshold would be to create 20 separated
oVirt logical clusters with 12 nodes per each ( and datacenter managed from
one ha-engine ) ?
*4.* In present, I have the folowing one 9 nodes cluster , all hosts
contributing with 2 disks each to a single replica 3 distributed
replicated volume. They where added to the volume in the following order:
node1 - disk1
node2 - disk1
......
node9 - disk1
node1 - disk2
node2 - disk2
......
node9 - disk2
At the moment, the volume is arbitrated, but I intend to go for full
distributed replica 3.
Is this a bad setup ? Why ?
It oviously brakes the redhat recommended rules...
Is there anyone so kind to discuss on these things ?
Thank you very much !
Leo

2018-09-17 14:27:03,467+08 INFO [org.ovirt.engine.core.vdsbroker.irsbroker.CopyImageVDSCommand] (EE-ManagedThreadFactory-engine-Thread-107849) [a407f6a9-445d-4ccc-b998-f9dfc6dc67ec] START, CopyImageVDSCommand( CopyImageVDSCommandParameters:{storagePoolId='79432500-ad45-11e8-98f3-00163e188641', ignoreFailoverLimit='false', storageDomainId='d9f2378f-92f0-4bc1-96a8-20a0f2c575cb', imageGroupId='ee55bbe7-8001-4c82-b1a6-0cac7710704b', imageId='701a7472-8c00-4b9f-aa87-4837eb128695', dstImageGroupId='8140d2e7-6908-438e-a646-23e58a33913e', vmId='b3aa623e-3072-430e-87d6-b81a3b07f466', dstImageId='c515a3f9-0590-4ebe-81c5-9d0993f1fec9', imageDescription='', dstStorageDomainId='d9f2378f-92f0-4bc1-96a8-20a0f2c575cb', copyVolumeType='LeafVol', volumeFormat='COW', preallocate='Sparse', postZero='false', discard='false', force='true'}), log id: 164e3046

I think maybe some command did not been excuted after I export the vm as OVA. I can find the similar case here:
https://access.redhat.com/solutions/1298893
I have used the tool unlock_entity.sh but cannot find any disk that is locked.
So what should I do to delete the disk that is been locked?

oVirt 4.3.5 glusterfs 6.3 performance tunning
by adrianquintero＠gmail.com
Hello,
I have a hyperconverged setup using ovirt 4.3.5 and the "optimize for ovirt store" seems to fail on gluster volumes.
I am seeing poor performance and trying to see how should I tune gluster to give better performance.
Can you provide any suggestions on the following volume settings(parameters)?

oVirt 4.3.5 WARN no gluster network found in cluster
by adrianquintero＠gmail.com
Hi,
I have a 4.3.5 hyperconverged setup with 3 hosts, each host has 2x10G NIC ports
Host1:
NIC1: 192.168.1.11
NIC2: 192.168.0.67 (Gluster)
Host2:
NIC1: 10.10.1.12
NIC2: 192.168.0.68 (Gluster)
Host3:
NIC1: 10.10.1.13
NIC2: 192.168.0.69 (Gluster)
I am able to ping all the gluster IPs from within the hosts. i.e from host1 i can ping 192.168.0.68 and 192.168.0.69
However from the HostedEngine VM I cant ping any of those IPs
[root@ovirt-engine ~]# ping 192.168.0.9
PING 192.168.0.60 (192.168.0.60) 56(84) bytes of data.
From 10.10.255.5 icmp_seq=1 Time to live exceeded
and on the HostedEngine I see the following WARNINGS (only for host1) which make me think that I am not using a separate network exclusively for gluster.
2019-08-21 21:04:34,215-04 WARN [org.ovirt.engine.core.vdsbroker.gluster.GlusterVolumesListReturn] (DefaultQuartzScheduler10) [397b6038] Could not associate brick 'host1.example.com:/gluster_bricks/engine/engine' of volume 'ac1f73ce-cdf0-4bb9-817d-xxxxxxcxxx' with correct network as no gluster network found in cluster 'xxxxxxxx11e9-b8d3-00163e5d860d'
Any ideas?
thank you!!

ovirt-imagio-proxy upload speed slow
by Dev Ops
I am working on integrating a backup solution for our ovirt environment and having issues with the time it takes to backup the VM's. This backup solution is simply taking a snapshot and making a clone and backing the clone up to a backup server.
A VM that is 100 gig takes 52 minutes to back up. The same VM doing a file backup using the same product, and bypassing their rhv plugin, takes 14 minutes. So the throughput is there but the ovirt imageio-proxy process seems to be what manages how images are uploaded and is officially my bottle neck. Load is not high on the engine or kvm hosts.
I had bumped up the Upload image size from 100MB to 10gig weeks ago and that didn't seem to help.
[root@blah-lab-engine ~]# engine-config -a |grep Upload
UploadImageChunkSizeKB: 10240000 version: general
[root@bgl-vms-engine ~]# rpm -qa |grep ovirt-image
ovirt-imageio-proxy-1.4.6-1.el7.noarch
ovirt-imageio-common-1.4.6-1.el7.x86_64
ovirt-imageio-proxy-setup-1.4.6-1.el7.noarch
I have seen bugs reported to redhat about this but I am running above the affected releases.
engine software is 4.2.8.2-1.el7
Any idea what we can tweak to open up this bottleneck?
