[ovirt-users] Re: Booting VMs from RHEL ISOs fail

2021-06-04 Thread David White via Users 
More details here:

I just tested this (new) VM now on a CentOS 7 ISO.
That worked perfectly fine.

But as soon as I tried to attach the RHEL 8 Boot ISO, it did not work.
The specific error I'm seeing is:

Boot failed: Could not read from CDROM (code 0095).

See below screenshot:

[ovirt-users] Re: Booting VMs from RHEL ISOs fail

2021-06-04 Thread David White via Users 
I uploaded the RHEL ISOs the same way I uploaded the Ubuntu ISOs:
Navigate to Storage -> Disks and click Upload (so using the wizard).

Once the ISOs are in place, I've attached them to VMs the same way I've 
attached Ubuntu ISOs: Select the Virtual Machine, click Edit, go to Boot 
Options, click the checkbox beside "Attach CD" and change the First Device to 
CD-ROM.

The oVirt Manager is 4.4.6, but the cluster compatibility is stuck at 4.4.5 
right now.
This particular problem has been ongoing, though, since before I attempted to 
upgrade everything to 4.4.6.

[ovirt-users] Re: How to handle broken NFS storage?

2021-06-04 Thread David White via Users 
When I stopped the NFS service, I was connect to a VM over ssh.
I was also connected to one of the physical hosts over ssh, and was running top.

I observed that server load continued to increase over time on the physical 
host.
Several of the VMs (perhaps all?), including the one I was connected to, went 
down due to an underlying storage issue.
It appears to me that HA VMs were restarted automatically. For example, I see 
the following in the oVirt Manager Event Log (domain names changed / redacted):


Jun 4, 2021, 4:25:42 AM
Highly Available VM server2.example.com failed. It will be restarted 
automatically.

Jun 4, 2021, 4:25:42 AM
Highly Available VM mail.example.com failed. It will be restarted automatically.

Jun 4, 2021, 4:25:42 AM
Highly Available VM core1.mgt.example.com failed. It will be restarted 
automatically.

Jun 4, 2021, 4:25:42 AM
VM cha1-shared.example.com has been paused due to unknown storage error.

Jun 4, 2021, 4:25:42 AM
VM server.example.org has been paused due to storage I/O problem.

Jun 4, 2021, 4:25:42 AM
VM server.example.com has been paused.

Jun 4, 2021, 4:25:42 AM
VM server.example.org has been paused.

VM server.example.org has been paused due to unknown storage error.

Jun 4, 2021, 4:25:41 AM
VM HostedEngine has been paused due to storage I/O problem.


During this outage, I also noticed that customer websites were not working.
So I clearly took an outage.

I don't have a separate lab environment, but if I'm able to reproduce the issue 
off hours, I may try to do so.
What logs would be helpful?

If I'm understanding you correctly, it sounds like you're suggesting that I 
just connect 1 (or multiple) hosts to the NFS mount manually, and don't use the 
oVirt manager to build the backup domain. Then just run this script on a cron 
or something - is that correct?

If it is, then I think it's either a bug in the firewalld module or in

In https://github.com/gluster/gluster-ansible-infra there is an example with :

We need to identify the var value.
Can you add something like this before the problematic task:- name: DEBUG  
debug:    var: server_cpu_list
In cockpit, before running it, there is an option to edit the playbook.

Please explain in more detail "went belly up".

In general vms not using he nfs storage domain should not be affected, but
due to unfortunate design of vdsm, all storage domain share the same global lock
and when one storage domain has trouble, it can cause delays in
operations on other
domains. This may lead to timeouts and vms reported as non-responsive,
but the actual
vms, should not be affected.

If  you have a good way to reproduce the issue please file a bug with
all the logs, we try
to improve this situation.

You need to understand the actual effect on the vms before you reject NFS.

NFS is useful for this purpose. You don't need synchronous replication, and
you want the backups outside of your cluster so in case of disaster you can
restore the backups on another system.

Snapshots are always on the same storage so it will not help.

NFS storage domain will always affect other storage domains, but if you mount
your NFS storage outside of ovirt, the mount will not affect the system.

Then you can backup to this mount, for example using backup_vm.py:
https://github.com/oVirt/ovirt-engine-sdk/blob/master/sdk/examples/backup_vm.py

Or one of the backup solutions, all of them are not using a storage domain for
keeping the backups so the mount should not affect the system.

I've destroyed and re-uploaded the ISOs, and I've also destroyed and re-created

Every time I try to boot a VM to a RHEL 8 ISO, the console just tells me that

Can anyone think of any reason why other ISOs would work, when RHEL ISOs do not

Hi Guillaume,

Have you moved the host to the maintenance before the upgrade (making sure
that Gluster related options are unchecked)?

Or you started the upgrade directly?

[ovirt-users] Booting VMs from RHEL ISOs fail

2021-06-04 Thread David White via Users 
Ever since I deployed oVirt a couple months ago, I've been unable to boot any 
VMs from a RHEL ISO.
Ubuntu works fine, as does CentOS.

I've tried multiple RHEL 8 ISOs on multiple VMs. 
I've destroyed and re-uploaded the ISOs, and I've also destroyed and re-created 
the VMs.

Every time I try to boot a VM to a RHEL 8 ISO, the console just tells me that 
"No boot device" was found.

Can anyone think of any reason why other ISOs would work, when RHEL ISOs do not 
work? How can I troubleshoot this further?
I really need to get a server up and running with Podman.

[ovirt-users] This year conference community updates

2021-06-04 Thread Sandro Bonazzola 
Hi,
as announced we are going to have oVirt online conference coming in
September.
I would like to give usual community updates in and as part of that I'd
like to report about oVirt downstream products (such as Red Hat
Virtualization and Oracle Linux Virtualization Manager) and about companies
using oVirt.
I could just go googling and guessing by e-mail traffic on oVirt users list
but I want to try a different approach this year.
So, if you are shipping an oVirt downstream or if you're using oVirt and
you'd like to get the company nominated during the community reports please
let me know off-list.
Also I'd like to remind that oVirt site has a section dedicated to user
stories, if you want to share yours you can either push it to
https://github.com/oVirt/ovirt-site or get in touch with me off-list to get
help getting your story published.

Thanks,

[ovirt-users] How to handle broken NFS storage?

2021-06-04 Thread David White via Users 
I'm trying to figure out how to keep a "broken" NFS mount point from causing 
the entire HCI cluster to crash.

HCI is working beautifully.
Last night, I finished adding some NFS storage to the cluster - this is storage 
that I don't necessarily need to be HA, and I was hoping to store some backups 
and less-important VMs on, since my Gluster (sssd) storage availability is 
pretty limited.

But as a test, after I got everything setup, I stopped the nfs-server.
This caused the entire cluster to go down, and several VMs - that are not 
stored on the NFS storage - went belly up.

Once I started the NFS server process again, HCI did what it was supposed to 
do, and was able to automatically recover.
My concern is that NFS is a single point of failure, and if VMs that don't even 
rely on that storage are affected if the NFS storage goes away, then I don't 
want anything to do with it.
On the other hand, I'm still struggling to come up with a good way to run 
on-site backups and snapshots without using up more gluster space on my (more 
expensive) sssd storage.

Is there any way to setup NFS storage for a Backup Domain - as well as a Data 
domain (for lesser important VMs) - such that, if the NFS server crashed, all 
of my non-NFS stuff would be unaffected?

[ovirt-users] Re: Adding a Ubuntu Host's NFS share to oVirt

2021-06-04 Thread David White via Users 
Thank you!
I decided to go with a RHEL 8 host, which worked perfectly fine. But that 
brings me to a new question, for which I'll start a new thread.

Is there any possibility to deploy host engine without any internet access? 
i.e. Is offline deployment of hosted engine possible?

I have added the following line at the end of the file 
/usr/share/ovirt-hosted-engine-setup/ansible/trigger_role.yml
environment:
https_proxy: "http://:"
http_proxy: "http://:"

But it gives error in the process of “hosted-engine --deploy”. I am not sure if 
this a typical issue in my company’s network but, it would be great if there is 
any offline installation method (without accessing internet repository).

I have also tried to use “hosted-engine --deploy
