    @Cygace Someone from the community may jump in and help troubleshoot this. The best approach would be to not modify the Dom0 installation by installing Zabbix via a community post, as you're customizing the installation. The vates team and XCP-ng specifically need to include these packages to ensure you're able to get support. Best of luck

    @Danp Thanks, yes of course. I got excited about fixing my problems and reported too early Well, the VM has been working fine since the export / import. I can see both drives. Although the VM running fine, since the last post I had to address two related VDIs that had been connected to the Control Domain. One being million_D and the other million_D (with a camera icon). These probably ended up here because of a aborted / faulty snapshot or backup. I disconnected them .. checked a few things ... and then forgot them. Everything is running fine now. For future googlers: During the problem solving, I found out some pretty helpful info using tail -f /var/log/SMlog. To me, this issue is solved. Thank you all for the feedback.

    @florent No, I did not see that in the logs. I did see this problem is bigger than I thought. It happens more often than just causing a VM backup failure. It happens during the merge or other checks which causes the backup process to destroy (remove) parts of other VM backups. Clean VM directory parent VHD is missing parent VHD is missing parent VHD is missing some VHDs linked to the backup are missing some VHDs linked to the backup are missing some VHDs linked to the backup are missing some VHDs linked to the backup are missing and Clean VM directory VHD check error some VHDs linked to the backup are missing

    If I felt that way and we never had issues in the past, it's maybe for a reason. I'm a very patient person (as you can read since years here). So you shouldn't be saddened but more trying to understand something you provoked (it's still not clear that you understand it). I think it's important to know when not to push too far, and you were clearly too far Next time you are frustrated on an open source software you use for free (likely in production otherwise you wouldn't have been that frustrated), remember that being kind will be more productive in the end. This will be better for everyone. Also I hope it's more clear for you that using things on master was never meant to be under our internal QA since it's not a controlled environment (but it's documented with big warnings. Maybe I'll make it even more clear in the doc, I don't know, I'm surprised you didn't get it since you are using it since a while. Maybe this misunderstanding explained part of your frustration).

    @jcdick1 I run opnsense on xcp-ng personally as well and use their packaged tools without issue, the only time I've gotten this behavior is when I hot-added interfaces and it changed the order of interfaces. If that's not it, I'm really not sure what would be causing this One last thing you can try in case it's a weird cash issue is (inside XOA) go to settings > servers, click the green connected button next to your xcp-ng server to disconnect it from xoa - then wait a couple seconds and click it again to reconnect it

    It is in the same place in XO. Network tab of the host. Change the Mode from None to Static (or DHCP). This should get you a pop up to enter the address, netmask, etc.

    You should probably be able to fix this issue by installing the ntfs-3g package. As you mentioned you're running it on a Synology, you can do that in DSM by opening Docker -> Container -> Select your container -> Details -> Terminal and enter the below in the console. apk update apk add ntfs-3g Let us know if it helped.
