[ovirt-users] noVNC error.

[tommy]

Hi:

 

I use novnc console can connect to engine vm.

 

But when I using novnc console connect to other vm in other datacenter,
failed.

 

The ovirt-websocket-proxy log is:

 

Jan 19 15:43:32 ooeng.tltd.com ovirt-websocket-proxy.py[1312]:
192.168.10.104 - - [19/Jan/2021 15:43:32] connecting to:

ovirt-websocket-proxy[24096] INFO msg:824 handler exception: [SSL:

What reason ?

[ovirt-users] Re: Managed Block Storage and more

[Benny Zlotnik]

Ceph support is available via Managed Block Storage (tech preview), it
cannot be used instead of gluster for hyperconverged setups.

Moreover, it is not possible to use a pure Managed Block Storage setup
at all, there has to be at least one regular storage domain in a
datacenter

There is no simple and reliable way to undo 'hosted-engine --deploy'.
It's not designed for that. 'ovirt-hosted-engine-cleanup' is only a
partial solution, and if it does not work for you, an OS reinstall
should usually be quick and easy (especially if you have PXE setup,
etc.).

This is unlike 'engine-setup'. engine-setup is used also for upgrades,
so it's very important that it cleanly rolls back to a previous clean
state if it runs into a problem. In that regard, 'engine-cleanup' is
not that important as well, although we do fix bugs in it.

'hosted-engine --deploy' should always be ran on a clean and new
system anyway, so if it runs into a problem, it should not be a loss
to reinstall the OS.

>
> But after weeks... I am running out of time.

Exactly. It's a tradeoff. It's simply not worth it.

Sorry for the time you wasted. Please reinstall :-).

That said, if you run into concrete bugs that can reliably be
reproduced, including in ovirt-hosted-engine-cleanup, please report
them! Thanks.

Good luck and best regards,

[ovirt-users] Re: Managed Block Storage and more

[Konstantin Shalygin]

Faster than fuse-rbd, not qemu.
Main issue is kernel pagecache and client upgrades, for example cluster with 
700 osd and 1000 clients we need update client version for new features. With 
current oVirt realization we need update kernel then reboot host. With librbd 
we just need update package and activate host.

Hm... this sounds bad . If it was deleted by oVirt, it would ask you whether to 
remove the disk or not and would wipe the VM configuration.

Most probably you got a data corruption there . Are you using TrueNAS ?

Most probably it will be easier if you stick with full-blown distro.

@Sandro Bonazzola can help with CEPH status.

Thanks Strahil for your reply.

Sorry just to confirm,

1. Are you saying Ceph on oVirt Node NG isn't possible?
2. Would you know which devs would be best to ask about the recent Ceph changes?

Thanks,
Shantur

[ovirt-users] Ovirt reporting dashboard not working

[José Ferradeira via Users]

Hello, 

Had a problem with the engine server, the clock changed to 2026 and now I don't 
have any report on the dashboard. 
The version is 4.2.3.8-1.el7 

Any idea? 

Thanks

[ovirt-users] Re: Managed Block Storage and more

[Shantur Rathore]

Thanks for pointing that out to me Konstantin.

I understand that it would use a kernel client instead of userland rbd lib.
Isn't it better as I have seen kernel clients 20x faster than userland??

I am probably missing something important here, would you mind detailing
that.

Shantur

[ovirt-users] Re: New setup - Failing to Activate storage domain on NFS shared storage

Hi Didi,
I did log clean up and am re-running ovirt-hosted-engine-cleanup && 
ovirt-hosted-engine-setup to get you cleaner log files. 

searching for host_storage in vdsm.log...

 There are users reporting using CEPH with their oVirt , but I can't tell

 I doubt that oVirt nodes come with CEPH components , so you most probably 
 will need to use a full-blown distro. In general, using extra software on 
 oVirt nodes is quite hard .
 
 With such setup, you will need much more nodes than a Gluster setup due to 
 CEPH's requirements.

[ovirt-users] Re: ovirt-ha-agent

[Yedidyah Bar David]

After you removed the hosts, and before you added them again: Did you
reinstall the OS? If not, there might be some mess left behind.
I suggest to try again: Remove a host, reinstall the OS on it, then
add it back and make sure you choose "Deploy". Then give it some time
to update (should not be more than a few minutes, let's say 1 hour).
If it still does not look good, please check/share all relevant logs.
Thanks.

Best regards,

Could someone please clarify the status of the discussed issue? Bugzilla entry 
https://bugzilla.redhat.com/show_bug.cgi?id=1782056
recently received strange update with a link to Red-Hat knowledge base. Does 
this mean that the discussed functionality actually works or can be made 
working with some efforts?

[ovirt-users] VM Disks order

[Erez Zarum]

When attaching a disk it is not possible to set the disk order nor modify the 
order later.
Example:
A new VM is provisioned with 5 disks, Disk0 is the OS and then later attached 
disks by order up to Disk4.
Removing Disk3 and then later attaching does not promise it will be attached 
back as Disk3.
In most other platforms it is possible to set the order.

Am i missing something? if not, is there a plan to add this feature?

Thanks Strahil for your reply.

Sorry just to confirm,

1. Are you saying Ceph on oVirt Node NG isn't possible?
2. Would you know which devs would be best to ask about the recent Ceph
changes?

[ovirt-users] Re: VG issue / Non Operational

[Christian Reiss]

Update & Fix:

There were remnant entries of filters in both

  /etc/lvm/lvm.conf and
  /etc/multipath.conf

that worked well with the Gluster LVM but went crazy with iscsi lvm mounts.

Fixed the entries, rebooted the server. Now it works and it is back up.

Cheerio!

I assume due to the changed LVM UUID it fails, right? Can I someone
fix/change the UUID and get the node back up again? It does not seem
to
be a major issue, to be honest.

I can see the gluster mount (what ovirt mounts when it onlines a
node)
already, and gluster is happy too.

Any help is appreciated!

27   3.ohost2   running

28   3.ohost3   running

 

The ooengh1 and ooengh2 are configured for hosted-engine, and ohst1 ohost2
ohost3 are configured for KVM server.

 

Now, I want to test the Power Management service using my test env, how can
I choose the fence protocol ?

[Andrei Verovski]

Hi,

I solved this issue.

dnf config-manager —set-disabled spp

For whatever reason HP hardware drivers repo conflicted with oVirt node install.
