    Did my 3 host production pool, only glitches were a few users that were logging in right as vms were migrating. Had a compressed day and had to just Yolo this morning instead of waiting until slower times. Getting paranoid about exploits, and it was Windows patch day too, so just jammed a bunch of stuff together this morning.

    @Greg_E said: @john.c Uggg... I just updated yesterday so I better check to see if I need to upgrade again today. Starting to hate AI, and I'm guessing the developers are the same. That said, not exposed to the internet. [edit] regarding moving the backup, it was nice to have a front page single click to see the checkmarks on the jobs. Now it's two clicks. I'll adjust my morning routine. @greg_e Itโ€™s just Vates and software in their stack, just imagine what itโ€™s like for developers and maintainers of Debian Linux! What with all the software in the distribution and all of it at times needed updating concurrently. To help them through these especially tough times may or would be a good idea to make a donation to Debian Linux, and/or other contributions.

    @tjkreidl said: @john.c Note that a two-host pool running HA can run into the split-brain issue if one of the hosts fails; it's highly recommended to have at least three hosts in an HA pool (or look into HA-Lizard if running a pool with two hosts and HA). Right but also considering the in development Twinstor for when it goes stable and in production!

    OK, marking this solved... It was the phantom reboots causing issues because the tools were not fully installed, only thing I can't understand is why only 2 out of 3 Windows servers would quit. Any way, got the Xen Tools updated and a couple reboots later, everything is working again. Also I can now report that a bug that was fixed maybe a year ago is confirmed to work in my system. The bug was backing up a Windows VM that had a lot of empty space in the drive (over 250GB free) and turning on compression. It would time out counting zeros because it thought the process wasn't doing work. Both of these VMs are now compressing with zstd, one of them is substantially smaller now, the other only shrunk about 20GB. Because of the way Windows uses the drive, these are all full backups. The differential never seemed to be small because Windows does a lot of changes on the drive (there is a post about this somewhere in here from Olivier).

    Thanks, that helps. Some VMs fail to the Synology but pass to S3, and some the other way round. So I think the backups on Ark are probably fine (they pass health checks, as you said at the start) and it has more to do with what each target already holds, but I could be wrong. I'd also flag the several delta jobs with different retentions all feeding Ark, I just don't know the mirror code well enough to say whether that matters. @Team-XO-Backend, posts 6 and 10 have the log and the pattern if someone gets to this one.

    For anyone else who steps through this, I've also installed the latest xen-guest-agent with the below process. Repeat for each host in the environment, 1 at a time from your Helper VM. ### ssh into your helper ### oc debug node/fedora-cmp-1/2/3 chroot /host cd /var/tmp curl -LO https://gitlab.com/xen-project/xen-guest-agent/-/jobs/6041686376/artifacts/raw/RPMS/x86_64/xen-guest-agent-0.4.0-0.fc37.x86_64.rpm sudo rpm-ostree install /var/tmp/xen-guest-agent-0.4.0-0.fc37.x86_64.rpm mkdir /var/tmp/xga && cd /var/tmp/xga rpm2cpio ../xen-guest-agent-0.4.0-0.fc37.x86_64.rpm | cpio -idmv ### From your helper... DRAIN YOUR WORKERS ### oc adm drain fedora-cmp-1/2/3 --ignore-daemonsets --delete-emptydir-data ### log back into fedora-cmp-1/2/3... ### sudo systemctl reboot ### from helper ### oc adm uncordon fedora-cmp-1/2/3 ### login to fedora-cmp-1/2/3 ### chroot /host sudo systemctl enable --now xen-guest-agent And then from XO this is what your VMs will look like.

    Veeam and XO backup CBT. How to avoid conflict?

    @zorro So with purge off, Veeam stayed clean for a few nights, which fits what I saw in the lab test. If I read the docs right, the cost is that XO's reference snapshot keeps its data on the SR again, which you'd notice more on thick-provisioned storage: https://docs.xen-orchestra.com/backups-and-dr/backup-types/incremental_backups#purge-snapshot-data-cbt. Storage hasn't said yet whether purge breaking another tool's chain is expected, so I'd still call this a workaround rather than the answer. If a CBT warning comes back when you add the other VMs, the Veeam task id and the time would probably help them. And keeping both makes sense to me, since Veeam doesn't do the cross-site replication you need XO for.

    @dthenot For anyone stuck, here is what I ended up doing: I've manually hardcoded the controller_uri in /opt/xensource/sm/linstorvolumemanager.py on the new host, restarted the toolstack using xe-toolstack-restart and ran the xe host-call-plugin host-uuid=NEW_HOST_UUID plugin=linstor-manager fn=addHost args:groupName=linstor_group/thin_device command. def _get_controller_uri() -> str: # TODO: Check that an IP address from the current pool is returned. #addresses = _get_controller_addresses() return "linstor://10.25.254.100" #return "linstor://" + addresses[0] if addresses else "" After that, you should see the addHost command return True. It should be safe to revert the change to the _get_controller_uri() function and restart to make sure everything starts properly.

If your VM couldn't boot after XenClean, XenBootFix executed from a recovery environment should get your VM working again.

    @acebmxer I haven't run your script, so I can't vouch for the log lines, but the systemctl status check looks like the safer of the two to me. It shows the binary the service is really running. Whichever node comes first in your shell can be a different one if more than one Node is installed. For XOA I'd go with what @Danp said above.
