oVirt hyerconverged more than 12 node
by wodel youchi
Hi,
Could someone explain the 12 nodes limitation when installing oVirt
Hyperconverged?
Our client has 16 nodes, can we use them on a hyperconverged installation?
for example creating two clusters, one with 9 nodes and the second with 6
nodes.
Regards.

Can ovirt implement FT functions
by xilazz＠126.com
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.

SAN re-attachment error
by 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

Reinstalling the whole infrastructure
by Markus Schaufler
Hi,
I’m not sure if my thread before is correctly received by everyone when posted via the website...therefore again via email.
Sorry if now everyone received this twice...
---
We are running our ovirt 4.3 test infrastructure on 4 Centos hosts. Our self-hosted engine further manages several stand alone hosts as separate datacenters.
We'd like now to reinstall the whole thing in a best practice way with oVirt node and a fresh hosted engine. We have planned to:
- set up 2 of the 4 hosts with ovirt node
- shut down the old hosted engine
- set up the new hosted engine with the same name
- move the VM's from the old cluster to the export domain in a maintenance windows
- import the VMs to the new cluster
- attach the stand alone hosts to the new hosted engine in again separate datacenters
Is this way possible to go or are there other ways e.g. without the need of a maintenance window?
Thanks for your thoughts!

Re: iso files
by suporte＠logicworks.pt
Hi Morris,
Yes. But first I needed to install de CA certificate into the browser 'cause I get this error message:
Unable to upload image to disk 8c96e460-87a7-4fb3-9f43-36dd278098c0 due to a network error. Ensure that ovirt-imageio-proxy service is installed and configured and that ovirt-engine's CA certificate is registered as a trusted CA in the browser.
http://<FQDN of your oVirt Engine WebGUI>:/ovirt-engine/services/pki-resource?resource=ca-certificate&format=X509-PEM-CA
Then upload the iso image file in the Storage – Disks area of the WebGUI.
When installing a VM I can attach the iso as a cd.
Is this the best way?
Thanks
José

Jose,
Based on this text at the following link it doesn’t seem to be required anymore.
https://www.ovirt.org/documentation/install-guide/chap-Configuring_Storag...
“ISO domains have been deprecated. ISO images should be uploaded directly to data domains from the Administration Portal.”

Hi,
is possible to install a VM without an ISO domain? for version 4.3.4.3 ?

Am I missing something? I've searched and found similar errors in previous version deployments that were found to be related to bugs, but those were said to be corrected in version 4.3.3. I'm kind of stuck at this point. Any help at all would be appreciated.
