[ovirt-users] Downloading successful, but checksum doesn't match

2022-11-07 Thread jb 

Hello community,

since yesterday I try to update my cluster, but when I was trying it 
through GUI it never finished and when I try it manually I got:


[MIRROR] ovirt-node-ng-image-update-4.5.3.2-1.el8.noarch.rpm: 
Downloading successful, but checksum doesn't match. Calculated: 
365a886b0a2784fa5304d7581970e56a312ab0789c4a97fd329bbd7313da736c(sha256) 
Expected: 
04979b883581b7ccb51ec063329b87a92bc5ea4405a161384cfdea68215e5306(sha256)


and it starts again the download process.

Before I also run: dnf clean all

Can it be, that something with the mirrors are wrong?

Best Regard

Jonathan

[ovirt-users] Re: storage high latency, sanlock errors, cluster instability

2022-05-31 Thread jb 
I still have the same problems, but it look like that the errors comes a 
bit less often.


I'm starting now to migrate the disk images to a NFS storage. When there 
is no other way, I would recreate the glusterFS cluster.


The problem I have is, that I don't know where is the root of this 
problem and if recreating would fix the issue in longer terms.

Hello everybody,

we run a 3 node self hosted cluster with GlusterFS. I had a lot of problem 
upgrading ovirt from 4.4.10 to 4.5.0.2 and now we have cluster instability.

First I will write down the problems I had with upgrading, so you get a bigger 
picture:

engine update when fine
But nodes I could not update because of wrong version of imgbase, so I did a 
manual update to 4.5.0.1 and later to 4.5.0.2. First time after updating it was 
still booting into 4.4.10, so I did a reinstall.
Then after second reboot I ended up in the emergency mode. After a long 
searching I figure out that lvm.conf using use_devicesfile now but there it 
uses the wrong filters. So I comment out this and add the old filters back. 
This procedure I have done on all 3 nodes.

When use_devicesfile (default in 4.5) is enabled, lvm filter is not
used. During installation
the old lvm filter is removed.

Can you share more info on why it does not work for you?

The problem was, that the node could not mount the gluster volumes anymore and 
ended up in emergency mode.

Yes I know, it was a bad workaround, but somehow debian had issues with 
auto mount cifs. I fix it now with enabling 
systemd-networkd-wait-online, but after I had to override the nginx 
service to, to wait for network-online.target.

Use systemd automount or autofs to fix issues with FS.

No everything by hand.


Any chance there is another system (outside oVirt ?) with the same MAC ?

you can run arping and check if you get response from more than 1 system.


I have check that to, but no the mac is unique.

The problem with " ifup: failed to bring up enp1s0" I could also solve 
and I think it has nothing to do with the problem. I used a custom 
script in /etc/network/if-up.d/ for mounting my fstab correctly.

[ovirt-users] Mount Export Domain only temporary

2021-06-23 Thread jb 

Hello community,

We use a NFS export domain for full backups. Sometimes I have to restart 
the NFS file server, but when I just restart that server, without doing 
anything in oVirt (I guess normally I should put the domain in 
maintenance mode), it can happen that hosts and VMs a crashing.


I had one time even the issue, that after a crash one XFS file system on 
one host got damage and I had to fix that.


My though was now, because I make only one time a week a VM full backup, 
I only mount the export domain in this time.


Is there an easy way to do this, with the API? Or would you have a other 
hint, how to solve this issue?



Have a good day!

[ovirt-users] Creating Snapshots failed

2021-05-27 Thread jb 

Hello Community,

since I upgrade our cluster to ovirt 4.4.6.8-1.el8 I'm not able anymore 
to create snapshots on certain VMs. For example I have two debian 10 
VMs, from one I can make a snapshot, and from other one not.


Both are up to date and uses the same qemu-guest-agent versions.

I tried to create snapshots over API and on web gui, both gives the same 
result.


In the attachment you found a snipped from the engine.log.

Any help would be wonderful!

Hi.

I have installed Ovirt nodes via the ovirt-node iso (centos8 based) - on a
fresh install the standard CentOS repos are disabled (the ovirt 4-4  repo
is enabled)
  

As part of our company hardening we need to install a few packages from the
Centos repos.
  

Can I enable the CentOS-Linux-AppStream.repo + CentOS-Linux-BaseOS.repo
repos or will this cause issues when we update the node ?

AFAIK it shouldn't break anything. ovirt repos have newer versions, so
anything required by ovirt should be installed from ovirt repo during upgrade.
I made the experience that after installing a upgrade, everything which 
I installed from that repos disappear.

You can try it with: virsh -c

For the error message no capabibilities is missing, it said bad cpu

Hi Lionel,

could you please run the following command on the non responsive host?

virsh domcapabilities

Also, could you please go to the Webadmin UI and check the warning 
signs on the host list and host detail to see, what flags is the host 
missing? You can also check the CPU Type on the host's detail page + 
all available cpus in the info icon next to it.

not sure.
4.5 cluster level adds IceLake which is Gen10, that should work with 
CentOS 8.3 newly.

It could be that your particular model is something in between…

Either way, if you really do need every feature from the CPU and 
you’re willing to sacrifice migration compatibility you can always use 
CPU host passthrough. Then it ignores any compatibility and just uses 
everything it can(everything that KVM supports) from the underlying CPU


No I don't need every feature. My concern was mostly, if I will have any 
performance downsides in normal scenarios.

[ovirt-users] Re: difference between CPU server and client family

2020-12-09 Thread jb 
Thanks Michal for the explanation. I will dive in this article and see 
if I understand it :-).


I use here the latest 4.4.3.12 Version. So I can hope, that newer 
version will support my CPUs better :).


Best regards

Jonathan

It’s usually a compromise between what the hardware has and what has

[ovirt-users] difference between CPU server and client family

2020-12-08 Thread jb 

Hello,

is there a big difference between *Secure Intel Skylake Server Family* 
CPUs and *Secure Intel Skylake Client Family* CPUs.


I ask because I use a Intel Xeon E-2246G in our servers and when I 
install the cluster, the client cpu model was automatically selected. 
I'm not sure now if it makes a different, when I change the cluster cpu 
type to the server model and if this is possible with this cpu.



Best regards

Jonathan

If you want to use custom partitioning, you have to use LVM Thin,
not the normal LVM Layout.

[ovirt-users] easy way to migrate to new engine

2020-11-16 Thread jb 

Hello everybody!

At the moment I have here a standalone engine and two nodes. Storage 
type is NFS.


Now I want to setup a 3 node self hosted cluster with Glusterfs and 
import my VMs from the old engine.


I know, there is a guide for migration from standalone to self-hosted 
engine, but there is so many changes (new Subnet/DNS names, different 
type of storage, new CPU type) that I would like to skip this migration 
guide.


Is there a different way to migrate my VMs? Mounting my old storage and 
moving the disks to the Gluster would be nice, but I guess I can not 
just mount a storage with existing VM images.


Best regards

I plan a new cluster setup, and for that I bought ASUS Barebone with

architecture is not in the supported CPU list from oVirt.

Hi Jonathan,
What is the error you're getting when you're trying to
upgrade using the upgrade guide?
Can you also attach the engine log?
(/var/log/ovirt-engine/engine.log)
Thanks,
Dana

On the cluster page is also a Upgrade guide, but this

Thanks for helping!

[ovirt-users] Re: Upgrade Host Compatibility Version

2020-10-07 Thread jb 

Sorry, last time I didn't answer to the mailing list...

Here are the output: *CentOS Linux release 8.2.2004 (Core)*

I use the kernel-plus, because of an old raid controller. Can this be a 
problem?

Thanks Jonathan
Can you tell me what is the OS version of the host that you're using? 
(cat /etc/redhat-release)

Hello Dana,

I added a second host, and tried again, without success.

The error is unspecific, it just says: *Upgrade of cluster default
failed.*

Here the engine.log

[ovirt-users] Revert to 4.3

2020-07-13 Thread jb 

Hello everybody,

at to moment I run ovirt engine in a VM on a different server (no hosted 
engine) and I have two hosts. One is only a backup and is not running.


I would like to install a new ovirt engine 4.4 VM and use the backup 
host. And if this is running fine in some month I would migrate the 
second host to 4.4.


The Problem is only that I have to upgrade the data center compatibly 
mode to 4.4 and with that I'm a bit afraid.


Is it possible, to downgrade the compatibility mode, when something 
unsuspected is happen?


The original 4.3 engine VM I would like to have untouched, that I can go 
back if is necessary.



Regards

Jonathan
