XCP-ng 8.2 updates announcements and testing

HeMaN

Installation now went well, no issues noted after the reboot.
Will keep an eye on my system and report back if anything unusual is happening

Andrew

@stormi Are these updates going to staging and be part of 8.2.1 or is this a February 8.2.0 security update before 8.2.1 ?

stormi

@andrew There will be a security update before 8.2.1.

stormi

Security update published. Thanks for testing! https://xcp-ng.org/blog/2022/02/11/february-2022-security-update/

stormi

The update that we named XCP-ng 8.2.1 is now published!

@stormi Updating my homelab (3x R210II, 2x R720) to 8.2.1 worked without a problem (apart from the fact that XO produced some hiccups with the rolling update). Nice

olivierlambert

@gskger I think we might have the same. Do you have an error log?

gskger

@olivierlambert I haven't looked for error logs (yet), but if you tell me which logs are interesting or what to look for, I'll be happy to give it a try.

stormi

@gskger mainly xensource.log, possibly daemon.log.

olivierlambert

I thought about XO Logs (in Settings/Logs).

gskger

@olivierlambert @stormi I will send you what I have tomorrow if it is not that urgent, ok?

olivierlambert

No rush at all Thanks a lot already for giving us that valuable feedback.

@olivierlambert @stormi I started the rolling update from XO and left it running alone since it usually takes some time to complete. This xenopsd internal error is from the XO log.

2022-02-28T15_21_32.891Z - XO.log.txt

An hour later I realized that the updates had been applied, but the hosts did not reboot. I tried to reboot the master from XO first which might have resulted in this XO log.

2022-02-28T16_35_04.612Z - XO.log.txt

After that all VMs including XO became unresponsive and I continued to investigate with XCP-ng Center. In the end, I decided to reboot the hosts from CLI (master first and than all slaves). That resolved the issue and XO came up without any further problems.

I have copies of the logs @stormi suggested from the master and one slave if they are needed. XO is XO from source by 3rd party script. I did an XO update after resolving the issue, so if you need the XO version, I can restore from backup and check.

Hope that helps.

olivierlambert

@Andrew I believe this is a problem on XO, unrelated to the XCP-ng update itself.

@gskger so we had the same issue. However, I did something differently: after restarting the toolstack, I could migrate VMs around without any problem, then reboot manually each evacuated host.

gskger

@olivierlambert Yes, restarting the toolstack first would have been a better approach. Is this something that needs additional actions on the hosts?

olivierlambert

No, that should be enough

stormi

We added a warning on the blog post https://xcp-ng.org/blog/2022/02/28/xcp-ng-8-2-1-update/ and will work on a fix in XO.

@stormi
now realise I had the same behaviour after applying the latest 8.2.0 security updates a few weeks ago.
At that time thought it was because I patched the master manually already (test repo release) and updated the entire pool only after the official release 2 days later (roling pool update).

So it is not (only) related to the 8.2.1 release

stormi

@HeMaN I think it's more likely to happen with the 8.2.1 update because more components are updated. Else I agree.
