@olivierlambert Sure! By way of example, when a new XCP-ng host is setup, all interfaces are created with an MTU of 1500 (even 10G interfaces). If I create a bond interface on top of two of the 10G interfaces, the default MTU is set to 1500. If I then create a VLAN interface on top of the bond interface, and set the MTU to 9000, XO happily lets me do so, but jumbo packets over it don't work because the MTU on the underlying interfaces is still 1500 (e.g. ping -s 1700 via the new interface fails). If I destroy and re-create the underlying interface (bond0) with an MTU of 9000, then re-create the VLAN interface on top with an MTU of 9000, then things work much better (ping -s 1700 via the new interface succeeds). Does this help? Thanks

It is test not prod. Next week, I'll probably tear it down & re-install with 8.2

@Chr57 Good job, always nice to have everything sorted out before going live

Your issue was unrelated to tools but a Xen upgrade from 4.13 to 4.17 without rebooting it (ie the libs were on Xen 4.17 while the hypervisor still running in memory was 4.13). A reboot solved that.

No problem, and it's not your fault, it's far from being intuitive. It will be a lot easier in XO 6. Also, enjoy discovering the cool little things hidden in this view (like trying XO in Chinese )

Yes, it should work if the migration doesn't fail It's hard to know exactly why it failed in your case, but it's unrelated on being XO VM.

@john-c Wow. What a "welcome" to a first post here. Thank you for all the information and you taking the time to write them. I'll write a better answer when I get a bit more time. Just wanted to say thank you.

the nfs share was having network connection difficulties, this was the cause. thanks for your suggestions.

I think this would be awesome, if it's not too much work, would love to see it.

that log appear again, without any actions from my side. [image: 1713513115366-bab449b6-55cb-4e9f-b0af-ce8e9bb19d22-%D0%B8%D0%B7%D0%BE%D0%B1%D1%80%D0%B0%D0%B6%D0%B5%D0%BD%D0%B8%D0%B5.png]

@CJ It may be easier to ensure reliability and prevent other possible issues from happening. I'm not an expert when it comes to the underlying code, but I would take an orphaned VDI over say some form of corruption or something like that. I'm guessing a little if I'm being honest, but cancelling it mid transfer might break some things, could leave a partial VDI that is locked for example, etc...

@gb-123 AFAIK the host doesn't call XO, if you shut XO off, the private network would continue to work but its state wouldn't change. It means if you restart an host etc the connection to this host would be lost. The logs depends on how your installed XO or XOA etc so you might want to go through our doc! Cheers

@ptunstall Great!

Hi, Because it's not implemented I'm not even sure if we have this info in the XCP-ng's API already (I mean VDI stats), probably worth checking.

@bdacasc said in Raid: @Danp I am running 8.2.1. The only thing I want to know if something happens to may softraid. Looking in the advance tab I only have "system disk health" and that is empty. It's not available on XCP-ng 8.2.1, it's only available in the beta 8.3, and eventually in the future release. That is why the "system disk health" is empty.

@palova XO can be installed and used from anywhere, you could even have multiple XO instances running simultaneously on different systems all with access to the same singular host, just avoid having those instances run backup jobs etc. It would be much easier to have XO running somewhere so you could administer this host before and post migration - that isn't running on either system. Make sure you export a copy of the running configuration from XO you have now so you can import it into the final XO system once all migration work is completed.

The task always has a progress, but I agree it's weird. We could update the UI to make it more logical in our next new UI

@gskger No problem, I just didn't understand the relationship with truenas' tls. I'll wait to see if anyone else goes through this and in the meantime I'll continue my studies with nbd. Thanks

@olivierlambert I have not. I looked at it last year but haven't checked on it since. I just tried it now and I remember one of the reasons I haven't used it. The self signed certs give my browser fits and I have to open each host up in a new tab to accept them by IP. The console UI seems to work the same in XO lite as in XO. There doesn't seem to be any way to copy and paste.
