    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.

    @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

    Your CR issue might be related to a XO bug on master, not too a XCP-ng issue

    Continuous Replication -> SR Disk space

    Hi, There is different things one must consider during CR: SR type: block based or file based? First one will be thick provisioned, so plan a lot of space (eg: local LVM, LVM over iSCSI etc.). Local ext/XFS, NFS or XOSAN aren't affected by this problem Snapshot left: to do a delta, we must have a way to compare to something. The snapshot which left on the SR is the one that will be used for the next backup. It will be compared to the current disk state and only the delta will be sent. So that's perfectly normal "Job canceled to protect the VDI chain": this is a protection to avoid doing another backup while the previous removed snapshot isn't coalesced. You have a link in the message, please refer to the documentation for details

    Continuous Replication -> Exchange Log

    @mts said in Continuous Replication -> Exchange Log: If you use the native windows-backup or a third-party application it will delete the transaction-log after backup. How can I achieve the same with xen-orchestra? I'm running low on disk-space right now... I think that you confusing physical (layer) backup with logical backup. XOA can backup/replicate/snapshot phisical medium which is a hard disk presented to your VM. It has nothing to do with the data in the VM (logical layer).

    Hmm I think it might be possible using xe CLI and creating the drives manually (creating VBDs I suppose). I never spotted such a use case before, but again, might be doable It is using VNC (via noVNC in XO). You can copy a template, but a template is just a set of "configuration" for your VM (eg PV or HVM mode, some virtual BIOS settings).

    Hi, If you are using XOA, please create a support ticket. This way our teams could take a look remotely to find the best solution.

    Thanks for the tip. I was using node v8.11.4 and had issues compiling during the upgrade then upgraded to the latest stable node version which wasn't v8.x. I upgraded to v8.16.2 now and it runs fine. Thanks.

    Indeed, 6.2 uses a very old configuration for keyboard mapping and therefore doesn't work correctly with XO.

    I switched due to SSD replacement and XCP-ng new installation. I didn't think about that switching from ext3 to lvm does also have an effect from thin to thick provisioning Anyway I found the explaination, here -> "a snapshot on a LVM based SR will double the whole VM disk size!" But I will think about to switch to ext4 -> topic solved, thank you!!
