Patching XCP-ng via XOA

[gthvn1]

You can also check if there are some logs in /var/log/updater-plugin.log

@rvreugde said in Patching XCP-ng via XOA:

xe host-call-plugin host-uuid=20cacce5-ffac-4ace-ac7c-e48f4e6dfc8e plugin=updater.py fn=check_update

Can you try to run the command directly on xcp-080 ?

I think, it has something to do with proxy settings.
XOA has its proxy set:

But, locally, via CLI, I got the following when I set the proxy

export {http,https}_proxy=http://192.168.91.151:8080

Check updates result (tried on several hosts):

xe host-call-plugin host-uuid=20cacce5-ffac-4ace-ac7c-e48f4e6dfc8e plugin=updater.py fn=check_update
Error code: -1

The /var/log/updater-plugin.log is empty.

I ran the command from xcp-080 (Pool Master) for another pool member (xcp-082).

[12:24 xcp-080 ~]# xe host-list name-label=xcp-082
uuid ( RO)                : fae5e2cb-a474-4541-8c30-8a5bc87ef945
          name-label ( RW): xcp-082
    name-description ( RW): Default install

This is the result:

[11:57 xcp-080 ~]# xe host-call-plugin host-uuid=fae5e2cb-a474-4541-8c30-8a5bc87ef945 plugin=updater.py fn=check_update

And if you run the command from pool master for pool master you still have an empty list?

xe host-call-plugin host-uuid=20cacce5-ffac-4ace-ac7c-e48f4e6dfc8e plugin=updater.py fn=check_update

Maybe this command must be run from pool master (I'll be surprised...)?

Deleting the lockfile works (had to do it twice). Could it be possible that XOA attempts are also responsible for creating this file?

rm -f /var/lib/xcp-ng-xapi-plugins/updater.py.lock

But after the command, the file is not deleted automatically.

In fact on my testing host (xcp-ng 8.3) the file is also there. So it looks like it is normal to not delete it. Can you run the command several times? Because on my host even if the file is not deleted I can run the command several times. So I guess that sometimes a process still holds the file and we need to delete it but most of the time the file is just closed and it works.
EDIT: Oh but in fact it looks like by default the update is run by XO so you will see the file that is updated (time is modified each minute on my host). But I'm discovering this plugin and I'm not sure how it is used...

Following process is keeping the file opne (not the manual command). Is it XOA?

@rvreugde it is really strange... I only have one host on my setup that I'm using for testing and I don't see this behavior... But I see almost every minutes a message in my /var/log/xensource.log saying:
Feb 10 14:55:58 xcp-gthvn1 xapi: [debug||518 HTTPS 10.1.0.100->:::80|host.call_plugin R:dd18d954e8e1|audit] Host.call_plugin host = 'd7f4a210-369a-410e-9c73-4acb59fe5e7c (xcp-gthvn1)'; plugin = 'updater.py' ; fn = 'check_update' args = [ 'hidden' ]
I don't know who is calling this. But for me the file is always released properly. No process that locks the file... Not sure about what to test next. Is there someone on the forum with the same issue?

It seems to be working on another pool, but, how can we get this working in XOA?
