[ovirt-users] Re: How to upgrade from ovirt 4.3.6 to 4.4.x ?

2021-06-06 Thread Strahil Nikolov via Users 
You will need to update to 4.3.10 first.Also 4.4 is using EL8, so you will need 
to reinstall one of the existing hosts or add a new temporarily.

2021-06-06 Thread nexpron 
I saw that daemon libvirt has stopped. Start result
/etc/init.d/libvirtd start
is
Starting libvirtd daemon: libvirtd: error: Unable to initialize network 
sockets. Check /var/log/messages or run without --daemon for more info.

I checked messages log, but I found nothing. So I edited 
/etc/libvirt/libvirtd.conf , uncommented line to get more verbose info
log_outputs="3:syslog:libvirtd"
and started libvirtd again. Result was the same as previous, but in messages 
log I found

I guess that libvirt is a problem, because vdsm work through that api own

The "non-offline-mode" is also for updating packages, not only for
appliance installation.

This is especially important because we not always release a new
appliance on new releases, so "non-offline-mode" makes sure you update
to the latest engine prior to engine-setup  - and this is especially
important on restore-from-file.

Indeed.

If you share vm xml for the ha vms and the regular vms it will be easier to
understand your system.

The best way is to use:

Do  you have a cdrom on an ISO storage domain, maybe on the same NFS server

Yes

Yes.

You can run the backup in many ways, for example you can run it via ssh
from another host, finding where vms are running, and connecting to
the host to perform a backup. This is outside of ovirt, since ovirt does not
have built-in a backup feature. We have backup API and example code using it
which can be used to build a backup solution.

If you have the engine volume content's intact, you can 'tune' 
ovirt-ha-broker/ovirt-ha-agent to start the HE in that specific Gluster 
TSP/volume.
Yet, It's far simpler and reliable to just restore from backup.

As far as I remember a feature was introduced that allows the end-user to 
verify the disk checksum after an upload.
Most probably it's not integrated in the WEB UI, but the API should have it.

[ovirt-users] Re: deployment fails - debug: var=server_cpu_dict

2021-06-06 Thread Strahil Nikolov via Users 
Thanks Didi,
it will be even better if we see the output of the debug with and without 
edk2-ovmf.

I reported a similar (identical?) failure at [1]. Please check that thread.

It seems like the recommended workaround is to remove (or not install)
edk2-ovmf.

[ovirt-users] Re: [oVirt 4.4.6] Offline deployment of hosted engine

2021-06-06 Thread Strahil Nikolov via Users 
Hi Didi,
can't we just make ansible check via ansible  package facts the status of the 
appliance and if it's available set to offline mode.I can take a look in the 
Ansible code for that purpose.Otherwise , the cockpit installer can have a tick 
for offline mode.
Best Regards,Strahil Nikolov

Please try with:

- appliance installed

- '--ansible-extra-vars=he_offline_deployment=true'

- latest released code (with your custom patch removed)

If it still fails, please open a bug and attach all relevant logs. Thanks!

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

2021-06-06 Thread Strahil Nikolov via Users 
That's correct.Ovirt knows and ensures that this NFS is available at all time 
and will take any actions to recover the situation.When you use autofs outside 
the oVirt, you still have that backup location and also it will umount when not 
in use.
