    Tracked it down to it thinking there was a pool version mismatch... then when I tried to transition to a new master it would fail with Xmlrpc_client.Connection_reset ... digging deeper it was complaining that it couldn't restore from the wrong version. Lots of head banging later... I setup a backup for the pool metadata and forced the backup immediately. TADA... I can now change the master with no issues at all.

    There are any commands that allow me to verify the integrity of the backup files?

    @florent , I tried the option of running "vhd-cli raw alias.vhd /dev/null". I was reading that vhd-cli raw copies the entire VM disk from the backup to /dev/null, reading the incremental backup file and the parent backup. But something seems off here. The VM disk in the backup has 133GB of block files within /data. And when I ran the tool, it took 7 seconds. The backup is on a USB hard drive (HDD), so I suspect the read speeds aren't higher than 30-60MB/s. Just reading all the blocks should take at least 40 minutes. Did I misunderstand how vhd-cli raw works? Tank you for your attention.

    Actually Alma Linux does have a variant for v2 CPUs so they can run 10.0. Just look for x86_64 v2 on the downloads page.

    @rtjdamen hey there, did you ever modify in the POOL advanced tab at the bottom the BACKUP network & MIGRATION network ? fiddle with these, note what they are actually set, and change them if possible between each change, check your SR stats @florent could explain better how SR stats use the backup network to get the RRDs... I guess you have stalled RRD tasks too ? in tasks list ?

    Thank you! So in this case, if better option for me to join the hosts to existing pool and then shutdown VMs and start it on host with older CPUs. Thank you again!

    @Cyrille said in DevOps Megathread: what you need and how we can help!: @afk Nice! I haven't tried Pulumi yet. Does Talos have a provider for it? I'm working on improving the CCM to make it work with Talos. Especially the cloud-node-label-sync controller (as the cloud-controller is the Talos one) to get the XO topology in the node labels. Yes there is a provider for it: https://www.pulumi.com/registry/packages/talos/ I guess its the auto-generated provider from the terraform one because I had some type checking errors in some places, but using python I could ignore that... I don't know if it has been fixed since. I remember reading some terraform examples on blogs to write the pulumi config so converting one to the other should be straightforward. Unfortunately, I can't publish what I wrote because its quite messy but feel free to ask if you have some blockers. The CCM would be nice to have indeed ! Good luck on that.

    For documentation purposes, there's a more general step of "Any VM you can shut down, do". Live Migration is great for VMs which need to stay up, but it's not free, and not even cheep. You will get done quicker if you can shut down VMs you don't need, migrate fewer things, and then (re)boot everything at the end.

    Yes, there's a possible weird combo between XOSTOR and HA in some situations. Let me add @ronan-a or @dthenot in the loop. It's likely that XOA disconnection is just a visible symptom of something else. It's not ultra trivial to reproduce though.

    Hey @Andrew, thanks very much for looking that up and providing the suggestions! Re. option 2: it's possible to just hide the T600 from dom0 and remove the R9 270 from the machine? dom0 won't complain that it's missing a GPU, or take control of the only GPU in the system?

    Ah indeed, labels are honored even in the case of a warm migration. We used it ourselves when we migrated from Intel to AMD CPUs, it was really the best compromise betweeen live and cold (especially when you change the CPU vendor). Glad to see it's helping many people and companies now

    If I remember some previous discussions, EVE-ng uses some features that doesn't work in nested mode with Xen.
