    @stormi I really appreciate the continued help. I'm not sure it works. On my single-host pool master—the one I want to join into my half-upgraded pool—I run the command: xe host-emergency-disable-tls-verification It returns with no errors. If I do xe host-param-list and look through the parameters for my host, I see: tls-verification-enabled ( RO): false This is the only thing I see documented that can turn off TLS verification. If some other command like pool-uninstall-ca-certificate would have the effect of disabling TLS verification, I can't see that documented anywhere. In fact, even though xe pool-uninstall-ca-certificate appears to be a valid command that my xe binary knows about, I can't find that particular command documented at all. Even after the emergency-disable-tls-verification, if I attempt to join that host to the half-upgraded pool (using xe pool-join...) I get: Error code: POOL_JOINING_HOST_TLS_VERIFICATION_MISMATCH It seems like even though the host has TLS verification off, the fact that its pool has verification enabled is blocking the action.

    Hi, Latest XOA, with fully patched XCP 8.3 here. I'm fiddling around again with NBD+CBT in backup jobs (was avoiding CBT for a time, to reliably control my backups and avoid unnecessary KEY points) in the context of THICK SRs to spare some space. I know that CBT is reset when migrating from one SR to another. But here is what I encounter : VM has no CBT enabled on its VDIs, it is on a SHARED SR in a pool of 3 hosts backup option changed for NBD+CBT, was only NBD before CBT is enabled on the next run by the backup job, I get a delta (was expecting a FULL ?) next run, delta, as expected i migrate this VM on another HOST, without changing its SR CBT is immediatly disabled ? why ?? next run of backup it tries a delta, but "fall back to a full" (normal as CBT has been disabled...), and do a KEY point on the remote next run is a delta as expected does this mean if I do a rolling pool update or host maintenance that will move the all VMs around, all CBT will be disabled and I should expect a FALL BACK TO FULL on all my NBD+CBT enabled backup jobs ??! why disabling CBT on a change of HOST and no move of SR ?

    It doesn't work like Citrix patches. Xen Orchestra will send a XAPI command to the host, that will in fact do a yum update command. The result is returned to XO and it will display available updates. We got a system using the best mirror for you: https://xcp-ng.org/docs/mirrors.html#original-mirror

    Hi, Please open a support ticket, that would be easier to assist (you can also open a support tunnel so we can remotely access your XOA to investigate faster, see https://help.vates.fr/kb/en-us/9-xen-orchestra-appliance-xoa/16-create-a-support-tunnel ) edit: don't forget to go in XOA/Support then doing an XOA check, see https://help.vates.fr/kb/en-us/9-xen-orchestra-appliance-xoa/17-xoa-check

    @station-already hehe glad you got it figured out Indeed, management interface changes are pretty "violent" in terms of how much they change and interrupt, so a reboot helps quite often - same for changing the virtual adapter/PIF assigned to a VM - alway a good idea to reboot the VM

    This means your NFS server doesn't support NFSv3.

    This is not exposed in XAPI, so it might require to write a XAPI plugin.

    @mrnaz look for the (first) error in your terminal where you execute the script to upgrade. Probably you need to upgrade the yarn or node version.

    @mauzilla I've done so that I have two separate backup jobs incremental every 4 hours, with exception on weekends. Retention usually 8 days weekly full backups, zstd compression, every Sunday night. This way we have a separate backup from the incremental chain. We also are able to do more maintenance jobs on the nfs server etc during the off hours on the weekend.

    @olivierlambert Thanks, We had been looking at Terraform so I guess we'll keep heading down that path for the time being.
