    @olivierlambert I have rebuilt the servers, and configured Pool networking successfully keeping the MTU at 1500. However when I create a VIF on one link for usage in a VM I kept getting data timeouts in ssh sessions and server (VM) access to resources, and setting the VIF and the underlying PIF to MTU 9000 resolved the issue. I am assuming I will need to do the same to the rest of my links, including the management one, but I dont want to end up in the same situation as before and lose my cluster. Any suggestions?! Thanks. Brett.

    hello running xcp-ng version 8.2.1 build date 2025-05-07 restart of node has been done netdata-ui version 1.19 release 6.xcpng8.2 from xcp-ng-updates repo netdata version1.44.3 release 6.xcpng8.2 from xcp-ng-updates repo confirmed following also installed xen-dom0-libs-devel yajl-devel xen-devel i have removed and reinstalled netdata-ui as well this was working fine before but sometime in the last few months , maybe when netdata updated to the versions above and the interface all changed, VM's are no longer visible in netdata [image: 1747811341191-c0b11d3e-0a0f-41dc-b122-4f1e769a92fe-image.png] use to be a giant list of VMs here, this is happening on all my xcp-ng servers, not just the one. they are all at the above mentioned xcp-ng version and netdata version. anyone else experiencing this? have any suggestions on whats going on, why the VM's are not showing up in netdata anymore on any of my hosts?

  • 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

    @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!!

    Change the remote in your job config. If you want to keep the previous backup there, just move or copy everything to the new remote.
