@MathieuRA Again thank you so much for you time trying to assist with this. The script OP has responded and updated the script to work correctly now. Again thank to all Vates staff for all the hard work you do that goes unnoticed.

@olivierlambert said in 2FA doesn't load graphics properly after XO6 went default (XO from source): Does it work OK without the proxy? Testing on my secondary lab, and the results are the same. Secondary lab runs privileged service, 443 without proxy.

@hitechhillbilly I'd say this is normal if you are low on RAM and you are doing a live VDI migration. XCP-ng requires some amount of free RAM on the host to be able to live migrate the VDI. The larger the VDI, the more RAM is needed but exact sizing is unknown to me. I've encountered this error numerous times so I consider it common. The way around this is to shutdown the VM and then migrate the VDI. RAM requirements in that case are much much lower.

@vaewyn There is an emergency transition to new master xe command. Also, make sure all your hosts are properly time syncronized to each other or there can be pool issues. Try first: xe pool-designate-new-master host-uuid=<new-master-uuid> If that fails, you will need to run on the slave server: xe pool-emergency-transition-to-master

@MajorP93 Thanks for your feedback. I'll look into it over the christmas hollidays

@benapetr Thanks, I will have to play with this when I have time.

@firereverie Sorry, these last few weeks was very-very busy. So I REALLY hope will do something on this before the december end and come back to you.

@Pilow I will take a look in deep later, but the key/delta and disk usage is set during backup, even if they are merged during LTR retention

@olivierlambert Thanks for the tip — it’s a very interesting mechanism. I’m going to read the docs now

In case anyone wonders how this played out. At the end of the day, I shutdown the host with the running workloads on it, kept it at BIOS boot so the 8.3 installer would upgrade it cleanly, and then booted it back up. For reasons related to my particular setup, the down time was more than 60 minutes. But that's not related to XCP-ng. The XCP-ng installer was maybe 10 of that. 20 of that was 3 reboots on a server that takes ages to boot. One thing that is a bit difficult is that the 8.3 installer doesn't notice ZFS volumes or help with ZFS. So after the upgrade, I have to follow a modified set of these instructions (modified because the package names have changed over time) to install ZFS and its components into the system. So the sequence is: Shutdown Install via ISO Reboot to single user mode Run yum update to pull in all the updates Run the ZFS commands to install ZFS on the host Reboot again Run normally Of course, I ended up rebooting more than just those 2 times, because I forgot that I would need to install ZFS (even though I did it on 2 different hosts already ) So now the pool is fully upgraded, everybody is happy. I'm now working on creating shared storage across the nodes. It's amateur hour over here. I appreciate all the help.

Another thing that I noticed: despite enabling remote syslog (to graylog) for all XCP-ng hosts in the pool /var/log gets filled up to 100%. Adding remote syslog seem to not change usage of /var/log at all. Official XCP-ng documentation states otherwise here: https://docs.xcp-ng.org/installation/install-xcp-ng/#installation-on-usb-drives The linked part of the documentation indicates that configuring remote syslog can be a possible solution for /var/log space constraints which seems to be not the case. I feel like logging could use some investigation by Vates in general.

Hi, I can't tell it's the cause, but you should first use an officially supported client to manage it.

@Greg_E said in XCP-ng Windows PV tools announcements: @john.c I'll have to update group policy and check that out, would be a time saver. Everything I use is an Enterprise level of some kind, using EDU in production right now, and Pro/Enterprise evaluation in the lab. I was looking at running a post imaging script to prevent some of the bloat, but a GPO might be easier. You can use Windows ADK to customise the installation media and build a custom ISO. That file can then be placed on your ISO SR. The GPO is especially effective when combined with a custom ISO built using Windows ADK. I have tried this myself and it’s very effective doing it this way, the Windows ADK tool is very powerful but will require time to learn. Will save time with all of the extra installations, if you use a custom ISO.

@denis.grilli really big news, I need to have XO STOR working Thanks for your problems and support correting them

The installer is built. We are testing it, then we will be able to provide it to you so you can test it in turn.
