    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.

    @florent this is where it's strange, all my 7 hosts were installed the same day, with the same patches... all 3 VMs were deployed the same day/way too why are 2 OK and not the third ? indeed CR is working, but DR is hiding something from me

    @olivierlambert said in Backup-NG Error "invalid header checksum" after VM-Disk-Resize and reaching retention Limit.: So the issue appeared just when the oldest extended delta had to be merged in the full I suppose. This is exact, but we need to have a proper process to reproduce it. This might be related to: increasing the size of the disk above a certain threshold increasing the content of the disk above a certain threshold

    After: mount 192.168.10.6:/mnt/raid/nfs /mnt/jan and i look with mount i get this: 192.168.10.6:/mnt/raid/nfs on /mnt/jan type nfs4 (rw,relatime,vers=4.1,rsize=131072,wsize=131072,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,clientaddr=10.211.55.19,local_lock=none,addr=192.168.10.6) So its working. After manual typing what XO tried: mount -t nfs 192.168.10.6:/mnt/raid/nfs/backup /mnt/jan -o vers=3 I get the same error: mount.nfs: access denied by server while mounting 192.168.10.6:/mnt/raid/nfs/backup So the “-o vers=3" option is the problem. Can i edit a file in XO to get rid of the “-o vers=3” option? SOLVED In XO i used the option -o vers=4 and this works.

    @olivierlambert said in Continuous Replication fails with VDI_IO_ERROR(Device I/O errors) on fresh XOA install after XenServer 7.2 -> XCP-ng 8.0 upgrade: To your config file, yes. Where this config file is depends on where do you installed Xen Orchestra (I suppose from the sources, so I can't guess where do you installed, could be anyware ) edit: I think it's fixed now and integrated by default in the config Great, this fix already is in the new version. I was having this problem (Error: VDI_IO_ERROR(Device I/O errors)) and was not be able to do CR of my VMs but now CR works. Thank you PS: BTW that was my config file

    @olivierlambert xcp-ng Center displays it properly, so yeah, it must be the way XO is pulling data. [image: 1565959684237-cpu.jpg] Oh well. Not a big deal. Just was curious. Thanks Olivier!

    When you click on the link of the error message it should send you to the official documentation, explaining what it means: https://xen-orchestra.com/docs/backup_troubleshooting.html#error-messages I'm not sure to understand the UI question, can you post a screenshot?

    cloud-init Network configuration

    Do you mean to say when you edit the network config box, and fill it out with your own network info (adhering to this standard: https://cloudinit.readthedocs.io/en/latest/topics/network-config-format-v1.html) that cloudinit in the vm gives a yaml error? This indicates the way you filled out the entry box is not properly formatted. Keep in mind to pass networking info, your cloudinit install in your template VM needs to be set to use nocloud data sources, and keep in mind the network configuration passed via cloud-init is added to the template VM, not replaced, so you need to properly configure your template VM to not already have adapters configured with IP addresses etc

    Yes, you are right infact the old instances are halted and are temporarily kept till I am not sure the imported ones are perfectly working on new node. Unfortunately in the meantime I need a way to manage boths and it means xencenter or cli. Thanks for having pointed my attention to the duplicated uiids problem.

    See me previous post here -- https://xen-orchestra.com/forum/post/5072 I'm guessing that you were missing the symlinks for the plugins, otherwise they should have been present in XO.

    I think the simplest way to just do this once is to go to Settings > Config, there you can export the backup. Once you create your new instance of XOCE, you can import the backup using the same page, then just logout of the default user, and you can login using your old credentials. Make sure to delete the admin@admin.net account after.

    So you can't create a backup with XOA Free. This edition is meant for all usual administrative tasks, like XCP-ng Center if you like. If you want backup features, 2 choices: going for XOA Starter, Enterprise or Premium depending on your backup needs. See each edition features here: https://xen-orchestra.com/#!/featuresmatrix (each edition comes with pro support, updater and remote SSH access if needed) install XO from the sources on a system you like, following our guide: https://xen-orchestra.com/docs/from_the_sources.html

    @axel I just ran the installation script on a Debian 10 VM and it worked as expected. Even when using the "official" way, sometimes the installation can fail due to things like -- issues with recent commit to github repo issues with upstream dependency etc This is why the pre-built XOA appliance exists. Feel free to open an issue over on the script's Github repo if you continue to encounter issues.

    This is a 3rd party container not validated nor endorsed by XO devs. We don't know what's inside, if you have questions on it, ask on the Github repo of the maintainer Backup reports will answer your initial question/requirement (reports can be sent by email, Slack etc.) There's also a Nagios plugin, or you can use XO API to make request to be support in any software of your infrastructure Monitoring a Docker container is outside scope of XO, I would suggest to ask Docker community. Regarding XO and how backup are done, any fresh XOA deployed (or from the sources) will be able to find all the previous backup done by an old XOA, because we store every info on the remote.
