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.

@exetico I have updated my script. Please use your previous install file (if you have it saved) to remove your previous version (remember to save your config before running uninstall), before you proceed to install the new version.

@stormi Great Idea! Post updated ! Update: I also added 'Automatic Backup' which backs up your original file in case something goes wrong.

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.

@ronan-a said in XOSTOR hyperconvergence preview: @peter_webbird We've already had feedback on CBT and LINSTOR/DRBD, we don't necessarily recommend enabling it. We have a blocking dev card regarding a bug with LVM lvchange command that may fail on CBT volumes used by a XOSTOR SR. We also have other issues related to migration with CBT. Is the problem still occurring on latest XCP-ng / XOSTOR version ? Not being able to use CBT on XOSTOR is a big issue for backup/replication.

Not until we can have our own piece of code doing it. Right now, it's a binary that's not Open Source made by Citrix, we cannot legally re-distribute it.

@olivierlambert Thank you. I thought maybe I was losing my mind/eye sight, especially after reading that google search indicating there was a start button in 6.

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

@McHenry Turning off the Manage via Windows update first + tools uninstall + reinstall should take care of it.

@dinhngtu I believe it was changing the guest TSC Mode that seems to have done the trick.
