Glad you asked.

Stefano's certs were not too old, they didn't expire. They were
invalid because they didn't have a timezone field. See also:

[Strahil]

Hm ... Removing it from the gluster but not inside oVirt can cause a lot of 
headaches.
Can you find that image in oVirt Storage ->  Disks

Sadly , you got no other option and the optimal approach would be to take the 
deletion from oVirt UI/API before the storage gets full.


Ovirt has the option to notify you in advance.

[Strahil]

Hi Sandro,

Thanks for the info.

I've just updated my lab (gluster v6.1 -> 6.3 ) and the only issue I have 
detected so far is that the Advanced Options  in UI show no info for the 
replica  bricks, while the arbiter is working.

So the situation is the same as before the upgrade.

[ovirt-users] SAN re-attachment error

[Kim Kargaard]

Hi,

I am running into an issue with my SAN storage on ovirt 4.3

I had an issue with the engine and re-installed and when I try to activate the 
SAN storage and DC (once linked) again, I get this errors:

VDSM node2 command HSMGetTaskStatusVDS failed: Cannot acquire host id: 
('fb14e013-15f1-49b6-b129-210517aca0da', SanlockException(22, 'Sanlock 
lockspace add failure', 'Invalid argument'))

Invalid status on Data Center Default. Setting status to Non Responsive.

The nodes can still all see the SAN and the LUNs.

I have tried restarting sanlock on the nodes, but the error persists. I have a 
vm with a disk on the SAN that I do not want to lose. Any thoughts?

Kind regards

Kim

[ovirt-users] Re: Issues when Creating a Gluster Brick with Cache

[Strahil]

The cache will not take immediately into effect. It is designed to save your 
cache disk and to load only repetitive data.
Try to run your  benchmark 20 times and you will notice slight improvement over 
reading the same object.

Of course , you can use lvm cache in writethrough mode, but then it is 
recommended to use 2 cache disks (raid1 or lvm mirroring) .

[ovirt-users] Re: HE on single oVirt node

[Staniforth, Paul]

Hello Mike,

I think the requirements for a gluster node is that it has 
at least 2 disks one for the O/S and the others for bricks.

It doesn't seem to say this in the oVirt prerequisites.


Could you reconfigure your raid device to provide LUNS?

Paul S.

Ok.  The oVirt Node installation sets up partitions to use the entire disk.  
(Documentation recommends using the default layout.)  The Cockpit HE deployment 
tries to use gluster, but on a different disk (non-existent).  Do you recommend 
that I not use the default partitioning when installing oVirt Node; instead, I 
should set aside a partition for gluster (not formatting, etc)?

Thanks,
Mike

Mike,

Keep it simple. It has to be a bare, plain disk.
Do not format or put a file system on the disk or the gluster install will fail.

The process does not seem correct to me.  Why would the wizard try to

[ovirt-users] vm unresponsive cpu soft lock on heavy operation

[Jayme]

Basic setup notes: 3 node HCI running oVirt 4.3.3 using nodeNG for hosts.
Storage is SSD backed with 10Gb network dedicated to gluster with jumbo
frames enabled.

The ovirt management network (which also acts as VM network) is 1Gb network

Hosts are dell R720s w/ 256gb ram and E5-2690 procs

I have a VM configured with 16Gb ram and 6 virtual CPUs.  When this VM does
a heavy operation (in this case it's dumping a large DB from a remote
server) the load spikes quickly.  When this happens the VM becomes
unresponsive and in some cases I get cpu soft lock messages.

I'm trying to determine where the bottleneck here is and how I can prevent
the VM from becoming unresponsive when doing heavy tasks.

Here is info from syslog showing the soft lockup:

[ovirt-users] Re: Error virNetTLSContextLoadCertFromFile after upgrade from oVirt 4.2 to 4.3.4

[Strahil]

What about setting the date and time manually somewhere at 2016 on all hosts 
and blockking ntp at all ?

Then the certs will be still valid and can be renewed ?

Just asking... Not sure what will be the outcome.

[ovirt-users] VDI Brokering

[Ciro Iriarte]

Hi!,

What's the usual way to implement VDI with oVirt?, is it usuallly
paired with a broker like UDS Enterprise / OpenUDS?, does it have
anything embedded that can solve the VM assignment for a group of
users?.

Regards.
CI.-

If I go with RDP, is there any requirement/trick on the endpoint

Use RDP.  (you may need to check your licensing with regards to running Windows 
VDI, there may be some cost)

Could you instead try an

# yum versionlock list

Maybe the CentOS repos are disabled by default, then versionlock status would 
be empty.

On an Engine system you have to call engine-setup again (don't worry)

packages.

But on an my engine there are no versionlocks, and there are the ovirt repos

you are right on this.

[ovirt-users] Proper way to upgrade hosts OS?

[Nicolas Ecarnot]

Hello,

We're not using nodes but CentOS 7.x hosts.
Do you know if some documentation has been written about the proper way 
to upgrade the operating system of the hosts, and especially how to 
prevent breaking dependencies or cause versions flaws?


Thank you.

Indeed. The engine is not working well with a database that is not
100% matching it (both schema and actual content). So we have
engine-setup that handles upgrades (clears versionlock, updates the
database and the packages, versionlocks again). It's not very nice but
that's how it goes...

You can also try 'yum history undo $ID' (after 'yum history' and one
or more 'yum history info $ID' to find the correct one).

That said, in principle the new engine could even have corrupted the
database, so even that does not guarantee success.

This check was added for the following bug, in 4.2.2 (so rather new -
it makes sense that you did mange to use one in the past):

https://bugzilla.redhat.com/show_bug.cgi?id=1549630

So it seems to prevent local storage domains on the root filesystem.
So you can/should probably try moving your storage domain to a
separate filesystem.

There is lots of material on ovirt.org, including many pages and many
many posts to the mailing lists.

I am not aware of any book-style "advanced documentation".

For this particular example, to find above bug, I did this:

Found the place in the source code that includes this scriptlet:

https://github.com/oVirt/ovirt-node-ng/blob/master/packaging/ovirt-node-ng.spec.in#L160

Search the git log for this file. You can do this in github ("History"
button), but I find it much more comfortable to use 'git log -u' and
search inside. This finds:

https://github.com/oVirt/ovirt-node-ng/commit/a46150de468fac72224762e67e4f7fddc2151783#diff-87ef1c528b1eda8356fb2204d7844cef

And this links to the bug.

I think that was certs made during first hosted engine installation.
Could it work if I manually create certs like this?
Just to start libvirtd, vdsm and hosted-engine.

I think it's worth a try. Just create a self-signed CA, a keypair
signed by it, and place them correctly, should work.

The engine won't be able to talk with the host, but you can then more
easily reinstall/re-enroll-certs.

Good luck,

This workaround works!
I have hosted engine running!

So I have to find how reinstall/re-enroll-certs on host. From engine
UI host status is "NonResponsive" and I can't do nothing
___

Status:

now Host status is "Unassiged".  Engine can't reach host for "General
SSLEngine problem" and It's ok because certs are "home made".
I can't switch host to maintenance because it's not operational.
I can't enroll certificate because is not in maintenance status.

You can try to remove it. I think we do not support "force-remove"
despite being asked about this occasionally, because
generally-speaking, this is very unsafe. If you insist, you can try
using the sql function DeleteVds to delete it from the database.


hou I can enroll host cert manually?

You can try following what I wrote in "2. Try to manually fix" before.
Create a CSR on the host (with whatever private key you want), copy it
to engine, pki-enroll-request, copy the cert to host.

Good luck and best regards,


I've just solved using  pki-enroll-request as you told me. Thanks!!
This upgrade was very very hard!!

You should wait for next node release and upgrade to that.

Nothing prevents you from removing lines from versionlock and running
'yum update', but I have no idea what happens on your next node
upgrade - e.g. if it contains newer packages that what you manually
updated, will yours take over (thus cause a downgrade), etc. If you
think you really need/want to do that, experiment carefully, and if
you think it's a valid need/request, please open a bug.

Hi Markus,

a Node installation is image based and this should not happen ...

On an Engine system you have to call engine-setup again (don't worry)
which updates installation files and then installs the versionlock'ed 
packages.


Best regards, Oliver

"Excluding 76 updates due to versionlock" !

Many packages are locked via the yum-versionlock plugin, also many system 
packages like the kernel and python (well, these 2 got my attention because 
there were security updates published recently). Isn't it recommended anymore 
to update the these packages to the latest versions? Do you use modified 
packages (different from CentOS?) Is it safe to remove the versionlock?

Best regards, Markus

[ovirt-users] Re: oVirt hyerconverged more than 12 node

[xilazz]

16-node your plan for creating two clusters works, and glusterfs ensures that 
at least three nodes in one cluster work if you want to use glusterfs.

[ovirt-users] Can ovirt implement FT functions

[xilazz]

Hi, now that ovirt has implemented the HA functionality of Shared storage and 
virtual machines, that's great.
In our daily use and maintenance, we sometimes need some functions of virtual 
machine FT. At present, VMware can realize FT functions based on VSAN.
Once upon a time there was a colo project, using qemu virtualization, 
https://wiki.qemu.org/Features/COLO, is now no one is updated.
I would like to consult ovirt about the project plan of FT.

Ok, the issue is here:
2019-06-17 13:50:04,014+0200 DEBUG otopi.plugins.otopi.dialog.human
dialog.__logString:204 DIALOG:SEND Please indicate a nic to

dialog.__logString:204 DIALOG:RECEIVEteam0.19

oVirt doesn't support at all the teamed devices but just bonds, please see:
https://www.ovirt.org/documentation/admin-guide/chap-Logical_Networks.html#bonding-modes

Unfortunately ansible facts module as for
https://github.com/ansible/ansible/issues/43129 also fails discriminating a
teamed interface from a plain one and so you were able to select it.

Yes, I am using the same two interface in bond configuration with one vlan for
