[ovirt-users] Re: New to oVirt - HE and Metric Store Question

[Strahil Nikolov via Users]

I send it unfinished.
Another one from Red Hat's Self-Hosted Engine Recommendations:

A storage domain dedicated to the Manager virtual machine is created during 
self-hosted engine deployment. Do not use this storage domain for any other 
virtual machines.

If it's a fresh deployment , it's easier to create a new LUN/NFS share/Gluster 
Volume and use that.
The following RH solution describes how to move HostedEngine to another storage 
domain: https://access.redhat.com/solutions/2998291

In summary: Migrate the VMs to another storage domain, set 1 host in 
maintenance , create a backup and then restore that backup using the new 
storage domain and the node that was in maintenance...

As I have never restored my oVirt Manager , I can't provide more help.

Avoid using HostedEngine's storage domain for other VMs.You might get into 
situation that you want to avoid.

[ovirt-users] Re: New to oVirt - HE and Metric Store Question

[Strahil Nikolov via Users]

I can't recall the exact issue that was reported in the mailing list, but I 
remember that the user had to power off the engine and the VMs... the Devs can 
clearly indicate the risks of running the HostedEngine with other VMs on the 
same storage domain.

Based on Red Hat's RHV documentation the following warning is clearly 
indicating some of the reasons:

Creating additional data storage domains in the same data center as the 
self-hosted engine storage domain is highly recommended. If you deploy the 
self-hosted engine in a data center with only one active data storage domain, 
and that storage domain is corrupted, you will not be able to add new storage 
domains or remove the corrupted storage domain; you will have to redeploy the 
self-hosted engine.

Is this the same case as in the thread:

? If so, let's continue the discussion there.

There are ovirt and an ovirt-dependencies repos. You need both.

[ovirt-users] Re: New Issue - Ovirt Status shows '?' or Down for all elements

[Mark Steele]

As a followup - is it possible to move the hosted-engine to another HV
manually? Meaning we shutdown the hosted-engine VM, and copy it's XML to
another HV and fire it up over there where libvirt IS running?

If that is possible, where do we find the live / running XML files on a
host?

All,

We've read some things stating to try running the engine-setup again to get
the certs inline. That is failing due to missing repo's - does anyone know
of alternative or archived repo's we could point at to get past that part?

That's why I asked  about the update.
The update  process renews  somee certificates, and as it wasn't updated  for a 
 long time - now you have  issues.

I hope  someone from the community can assist you.

My recommendations:
1. Check on all hosts  all vdsm.log  and extract the  VMs' xml
2. Get all network's xml

Recovering Virtual Guests in “Unknown” status after losing access to storage You must reset the VMs state into database to recover it from “Unknown” status . Thanks [1]1. If VMs with unknown state still works - shutdown it normally.You must shutdown VMs to prevent data lose.2. Connect to engine PostgreSQL database.3. Grab the VM GUID# SELECT vm_guid from vm_static WHERE vm_name='server01-examplecom';4. Set the status of virtual guest to a status of “0”# UPDATE vm_dynamic SET status=0 WHERE vm_guid='df13ca7f-b6fa-4820-8a7b-28d785221b64'; [1] - https://www.dalemacartney.com/2013/02/17/recovering-rhev-virtual-guests-in-unknown-status-after-losing-access-to-storage/   01.04.2020, 20:49, "Mark Steele" :A million years ago - we are going to be upgrading with a new cluster but for now, we have this one. It's production and we cannot take it down unless absolutely necessary. ***Mark SteeleCIO / VP Technical Operations | TelVue CorporationTelVue - We Share Your Vision16000 Horizon Way, Suite 100 | Mt.

[Mark Steele]

More information:

- the host that ovirt hosted engine is running on is not running libvirtd.
When we attempt to start it, it complains about expired certs and fails.
Any ideas on this new development?

A million years ago - we are going to be upgrading with a new cluster but
for now, we have this one.

It's production and we cannot take it down unless absolutely necessary.

[ovirt-users] Re: New to oVirt - Cluster questions

[Strahil]

In my setup, I have 2 AMD hosts +  an Intel-based arbiter.
Actually , if you separate them in 2  different clusters (1  for intel + 1  for 
amd) - you  can run VMs on any of the nodes.

So you can host the arbiter as a VM or get a 3rd machine for it. I think a VM 
(with decent storage) is  enough for the arbiter  , but you should test prior 
putting the oVirt setup into production.

[ovirt-users] Re: New to oVirt - Cluster questions

[Strahil]

Hi Adam,

The arbiter holds only metadata for gluster to be able to resolve any potential 
split brains. It can run on another host (not in the 2 replicas)  and the only 
requirements are:
1. Low network lattency - you don't want to put it in Chona, unless your 
replica servers are also there :)
With remote arbiter - the lattency will affect you only when 1 of the replicas 
is down.
2. Fast storage that can easily create the files' inodes. I would preffer a SSD 
, but even high speed rotational disks are OK

In other words, you should create gluster bricks like this one:
server1:/gluster_bricks/myvolume/brick1
server2:/gluster_bricks/myvolume/brick1
arbiter:/gluster_bricks/myvolume/arbiter_brick

In this case, if a node dies - the other node + arbiter will have quorum and 
will serve any I/O for oVirt.
The arbiter_brick does not require much space, as only metadata will be written.

Actually with hyperconverged setup you have 2 clusters on the same nodes - 
storage (gluster) & oVirt (virtualization).

Jayme,

Could the arbiter be a VM hosted on another host Host 3?   I do have another 
server that I could use, but it does not match the 2 main hosts. (Host 3 would 
not actually be used for VM storage/running VMs.)

Hello Strahil,

Thank you for getting back to me.  The arbitier machine is similar to a hyper-v 
Quoroum, is that correct?  I come from a Hyper-V world, and am getting familiar 
with the terminology here.  If that is true, can he arbitier be a VM hosted on 
another separate host?  In other words, I have 2 hosts that I would use for 
ovirt.  I have another host that is only used as a backup device.  Could a VM 
on the backup host be used as an arbitier for the cluster?

[ovirt-users] Re: New to oVirt - Cluster questions

[Strahil]

Hi Adam,

The problem with replica2 volumes (1 copy on 1 server , 1 on the other) is that 
you may be in split-brain easily.
Thus ovirt accepts only replica3 or replica2  arbiter1.

If you have a small system with an SSD , then you can create your arbiter 
there. My lab has a Lenovo M-series for an arbiter.

Guster (not talking about Glusterd2 here) will very soon support another 
feature called remote arbiter which will allow you to bring an arbiter in the 
cloud (or any other remote destination) and the latency will not cause any 
issues.


Keep in mind that due to the nature of linux bonding/teaming it's better to 
have high bandwidth NIC vs multiple small ones ( 2 NICs x 10 gbit/s brings 
better performance  vs 20 NICs x 1 gbit/s ).

So, you need a 3rd node - no matter locally (regular arbiter or a full replica 
) or remotely (remote arbiter).

Of course for testing, you can still setup gluster (manually) in a replica2 
volumes and use oVirt ability to use POSIX-compliant FS . This type of setup 
will not be supported and you won't be able to use the UI but you can still 
explore the oVirt project.

[ovirt-users] Re: New to oVirt - Cluster questions

[Jayme]

Ovirt can be installed on as little as one node ,but for a proper HA setup
you should have at least three nodes.

Hci uses gluster and needs a replica 3 or replica 3 arbiter 1
configuration.  With arbiter you need less storage as it only holds
metadata so you might be able to put a third server in your mix without
having to spend a lot on storage for it.

I would not attempt HA with anything less than three severs unless you are
using external storage such as nfs.

I just discovered oVirt, and before installing, I'm already a fan.  I have a 
question regarding the number of nodes needed for a cluster. My main end goal, 
is to have HA, where I can have live migrations.I currently have 2 nodes (2

I can't seem to find a solid answer for this question.  I've read the

this possible?

 Thank you all for suggestions.
I end up installing centOS and OVirt Engine on one machine, and OVirt Node on 
another.
Until I get more familiar, this is going to be fine.

  Could you tell what problems you're having and what documentation you're

 I just did a hyperconverged hosted-engine setup on a single server using the

 Going todo it tomorrow again to get a collegue to work on it so if anything

 So I did the same routine today and followed this piece of documentation:
 https://www.ovirt.org/download/ --> Install oVirt with Cockpit
 Used a std Centos minimal install, used a fixed IP address with a DNS A record 
and a PTR record, made one for the engine too!!, ran yum update, reboot

 sudo yum install ansible-glusterfs-roles #??? not sure about the exact name 
but use yum info *ansiblie* | grep ^Name | sort to find it. Wizard needs them.
 login into cockpit
 Select the gluster HCI wizard instead of the HostedEngine one and follow the 
instructions to the t, use fixed IP adresses which DO have a DNS entry, saves 
you a lot of hair pulling.

[Derek Atkins]

Hi,

When I installed oVirt (on CentOS 7.2 using 4.0.x in October 2016) I
used the following sets of instructions:

https://access.redhat.com/documentation/en/red-hat-virtualization/4.0/paged/self-hosted-engine-guide/chapter-2-deploying-self-hosted-engine
http://www.ovirt.org/documentation/how-to/hosted-engine/#fresh-install

I did take a few trials to get it right.

I made sure I had CentOS fully installed, set up my local file systems,
NFS (for storage domains), permissions, networking, etc.  Then I
installed and did the hosted-engine --deploy

Then in the hosted engine VM I also installed CentOS manually and
installed the hosted engine itself.

It did take me a while to get it all right.  I did need to run
hosted-engine-cleanup.sh at least once.  :)

But it's been very solid for almost 3 years now.  I'm due for another
upgrade soon.

[ovirt-users] Re: New to OVirt

[Slobodan Stevanovic]

 I am currently at the point that I am thinking on giving up and start playing 
more with Proxmox.
Do you guys have any suggestion on what instructions I should use? I just want 
to setup something to get a better idea on how everything works before I go to 
more advance things.
Currently, downloading Ovirt Node from https://www.ovirt.org/download/node.html 
and running Cockpit does not work form me.

so I had to track down where it migrated too.

[Dmitry Filonov]

Absolutely. It is Rock solid. It is great idea and definitely way to go
when you are comfortable with the technology. But for the new user it might
be confusing at first. And in general it adds a bit of complexity that you
don't need.
Especially if you do have that extra piece of hardware to use for it in the
beginning.

[ovirt-users] Re: New to OVirt

[Derek Atkins]

The only issue I've had is that it can take 15 minutes before the HE 
starts...  And I have to ensure the host is taken out of maintenance mode 
manually.  Beyond that, it has recovered from many updates, reboots, and 
power hits without intervention.

Not like huge issues, but something like you put host in to global HA 
maintenance, then update hosted engine, reboot and... and it doesn't start.

Not a big deal, but for a new user it might be a bit confusing.
So am with Michael, if you just starting using oVirt then it's better to 
have standalone engine et first. And then migrate it over into hosted 
environment when you are comfortable to do so.

Disagree, I've had some pretty significant meltdowns and if you cant access

self-repair and find a scrap of a host to run on is pretty impressive.
