@olivierlambert hi, will do. Not sure what happened, I used the source compiled versiom first, where it was missing. Think I had to register to get the updates and that version worked. Thank you!

@olivierlambert hi, I wasn't up to date I think. it works on the latest version, thanks!

Sorry that I cannot answer your question, but on the topic, I am wondering if the recipe source is available anywhere public?
I am interested because I would like to create a recipe for OKD, the upstream version of RedHat OpenShift.

That way I could probably help troubleshoot this kind of issue.
I also have not found any documentation and when trying to use static IP it is unclear to me with 3 nodes and 3 control planes what the VIP should be set too for example.

I will soon start with a manual install, but I am waiting for hardware at the moment because of the memory and CPU requirements for OKD.
When I pull it off manually I would love to use the recipe based automation of it.

I didn't find a solution, it looked like a change of the host that affected network. Rerunning from USB with latest beta kept showing an upgrade.
Network reset did not fix it and the machine was laggy, like when I tried to join from XO ( via settings ).

I just did a complete reinstall, disabled HA on the NFS SR, joined pool and it worked and re-enabled HA.

Seems ok now, thanks for the help.
By the way, is there a way to join a node to the main pool in XO ?
Thanks!

attached two more log files that were made around the time of upgrade.
It looks like the USB was mounted and that it disturbs the XAPI somehow?
I restarted that also and it shows ok. Gonnna keep looking :).2023-08-19T23_42_06.565Z - XO.log.txt 2023-08-19T23_41_59.940Z - XO.log.txt

@Danp sure, recommended. but this is not per se a result of a quorum issue? I basically wonder if the host can be brought back into the cluster - the issue and errors are unclear to me, I do not understand what the problem is and how to prevent it.
3rd host is underway, but I see no reason why it would not happen then. I thought to keep the issue to trace bugs. I was unable to join the host successfully from XO by the way - but I guess I should address that in another post? I am looking for operational troubleshooting knowledge I suppose.

Thank you, then let's see who else knows something.

[16:47 xcp-ng-2 ~]# xe task-list
The coordinator reports that it cannot talk back to the supporter on the supplied management IP address.
ip: 192.168.68.54

That is on the command line.

@Danp Thank you for the quick reply!
I upgraded the master first yes.

• with cluster I mean two machines with shared NFS storage (HA enabled) that are joint in the same pool
• in XO - the node shows offline. When trying to start it, it shows the host is offline, I will attach the XO log

I think the solution is probably just to reinstall the node, but I have seen this multiple times reported and wanted to understand it and learn how to fix it ideally.
It looks to me the XAPI is somehow not working and I do not understand the storage shown in XO - when I type mount on the host is does not show.[2023-08-20T14_41_50.142Z - XO.log](Invalid file type. Allowed types are: .png, .jpg, .bmp, .txt, .jpeg) 2023-08-20T14_41_50.142Z - XO.log.txt

I have a simple home lab of two machines. I have had several issues running a cluster, mostly because I could not join a node properly with XO.
So I joined it via the command line and it went fine.

Then I tested upgrading : latest beta via USB. For the non master it showed an upgrade which I can. In the end it shows offline.
When trying to join it I get :

 Host Failed to Join the Pool          

("'NoneType' object has no attribute 'xenapi'",)

In XO it shows offline, although I can connect to the console.
Strangely, the local storage for that node shows a full partition:
location: /dev/xapi/block ( local, unshared , 3,7 GB ).

What could have gone wrong here?
Thanks

@dj423 thank you, that is really helpful!
I also found : https://cloudinit.readthedocs.io/en/latest/reference/examples.html

Some things are mentioned here :
https://xcp-ng.org/forum/topic/7177/cloud-config-success
that you did not seem to need ? I will try it out.

I saw the Kubernetes recipe uses cloud config files and I am interested to use it for an OKD installation.
I really like XCP-ng so far, cheers!

@dj423 Thanks for sharing. Would you mind adding the config file you used ? thanks!
