    I noticed that a single CR backup job creates two VMs in each pool. Also, I found an unavailable button in the backup task. [image: 1774524737179-31572c2f-d359-49ef-bc43-1995064a8521-image.jpeg] I don't understand when or what exactly was changed.

    We are trying to use the OIDC auth plugin to enable login to our Xen Orchestra without local accounts. We registered a client with our identity provider and got a client id, client secret and the auto-discovery url. That we used to configure the plugin. However, if we login we get redirected back from the identity provider to the XO callback url and receive then an "Internal Server Error" The callback URL is as follow: https://xoa.domain.com/signin/oidc/callback?state=STRING&scope=profile+openid&code=STRING&iss=https://identity-provider.url&client_id=XXXXX In the log file we see then the following 4 lines: mrt 25 12:29:25 vm-xoa xo-server[2618522]: Expected values to be strictly equal: mrt 25 12:29:25 vm-xoa xo-server[2618522]: + actual - expected mrt 25 12:29:25 vm-xoa xo-server[2618522]: + 'undefined' mrt 25 12:29:25 vm-xoa xo-server[2618522]: - 'string' If we change both the username field and the scope to email, we get the same Internal Server Error, but with a different single log line: mrt 25 13:18:04 vm-xoa xo-server[2618522]: Cannot read properties of undefined (reading '0') Because we are getting redirected back from our identity provider to Xen Orchestra we guess that the issue is not there. We also get in the browser a SAML response with the userdata. Running a wireshark on the server shows also traffic between Xen Orchestra and the identity provider, but unfortunately we cannot look in the contents of that traffic stream. Setting the log level to debug does unfortunately not produce more (error) output. We are running Xen Orchestra with commit c3dcb and the auth-oidc (v0.4.2) plugin Is there an other way to figure out what is going wrong?

    Setting up a solid backup strategy is always such a relief once it's actually dialed in. It's really helpful to see the different approaches laid out like this, especially for finding that balance between reliability and ease of use. This definitely gives some good food for thought for anyone looking to refine their setup.

    Version 1.4.0 is released: https://codeberg.org/NiXOA/system/releases/tag/v1.4.0 It includes significant changes and improvements, including: dedicated getting started section, migration to valkey, only needing to clone system, and helper scripts. the xen-orchestra-ce nixpkg now references the libvhdi nixpkg, and the core flake now references and pulls from the xen-orchestra-ce repo as an overlay. System (the user input flake) now uses the Core repo as an overlay, reducing the need to clone both locally AND allowing system to pull new updates and releases from core. XO, and libvhdi as needed. The next goal is: Make an xsconsole-like TUI Automate package updates for libvhdi and xen-orchestra-ce using CI/CD pipelines Submit libvhdi and xen-orchestra-ce as official nixpkgs

    Indeed, if your other hosts are somehow dead/unresponsive from XAPI perspective, ejecting them from the pool is an option to get your master booting those VMs

    Restore File - Long filenames not displayed correctly

    @pdonias I am puzzled. What do you see? To be clear there are two problems. The selected directory truncates the directory name at around 46 characters ("/var/lib/docker/containers" in my original screen shot isn't truncated because it isn't that long). "Long" file/directory names in the "Select a file" drop down do not display correctly. Once a file has been selected, the "Selected files/folders" does show it in a scrollable "widget" that can then be used to see the full file name. My screen shots are from Chrome on Fedora. I normally use Fedora/Firefox which has the same issues. I set up the following as a test. Filename lengths are 10-80 characters long. root@debian42:~/testdir# pwd /root/testdir root@debian42:~/testdir# ls -l total 0 -rw-r--r-- 1 root root 0 Oct 7 09:50 1234567890 -rw-r--r-- 1 root root 0 Oct 7 09:50 12345678901234567890 -rw-r--r-- 1 root root 0 Oct 7 09:50 123456789012345678901234567890 -rw-r--r-- 1 root root 0 Oct 7 09:50 1234567890123456789012345678901234567890 -rw-r--r-- 1 root root 0 Oct 7 09:50 12345678901234567890123456789012345678901234567890 -rw-r--r-- 1 root root 0 Oct 7 09:51 123456789012345678901234567890123456789012345678901234567890 -rw-r--r-- 1 root root 0 Oct 7 09:51 1234567890123456789012345678901234567890123456789012345678901234567890 -rw-r--r-- 1 root root 0 Oct 7 09:51 12345678901234567890123456789012345678901234567890123456789012345678901234567890 Filename lengths 10-50 display. Filename lengths 60-80 do not. [image: 1665091374720-screenshot-from-2022-10-07-10-22-26.png]

    @olivierlambert i did update xoa again but no dice, i was wanting to export a couple VM's and do a head to head iscsi I/O test between vmware and xcp on identical hardware but not having much luck trying to get my VM's out of xcp. Guess I'll have to wait for this to work possibly.

    @MichaelCropper said in XO Backup Failing - Possibly to due Local Disks and loopback issues?: Job canceled to protect the VDI chain This usually indicates that there are VDIs that haven't coalesced. Check the "unhealthy VDIs" section of Dashboard > Health.

    @daninmanchester Thanks so much - this is the exact same problem I had, which was further complicated by running XO in Docker running on the OMV host exporting the NFS shares. So basically you just built a small XO VM instead of running it in Docker? I had originally been thinking of making a small VM to run XO in a container there - just because Docker containers are super easy to keep updated and I could run some other orchestration-y stuff there too, like Rancher - but if you're saying that's a non-starter I'll just bite the bullet and build a tiny VM dedicated to XO and be very grateful to you for having saved me a lot of frustration.

    @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
