XCP-ng 8.3 betas and RCs feedback ๐
-
Regarding the fact that the upgrade asks for the network configuration for hosts which are not the pool master: we checked, it's been the case in this installer code since more than ten years. At some point, the installer needs to contact the pool master during the upgrade.

@stormi Good to know, thx.

Weird incident here, my server froze for no reason at all (none that I can know yet), I don't even know for how long it has been frozen since the VM I use every day is working. I cannot ping Xcp-ng server, it is registered but cannot be connected via Xen Orchestra. I did not run the 2 latest batches of updates on my XCp-NG 8.3 server. The weird thing is that most of my Linux VM are still running and reachable!! The Windows VM, on the other hand are not reachable. Any recommendations for investigation before I reboot the host server? It is running on a Supermicro and I can see the frozen main screen via iKVM and it does not respond to keyboard inputs, not even from the virtual kvm keyboard.

I suppose you cannot have any physical access to check on a screen?
-
@olivierlambert There is no physical screen attached to it. I am currently investigating the SSD that was booting CXP-ng. I am guessing it just died on me. Will update if I can read any data from it.
- Any specific log I should look at if any available?
- If I restart from scratch with a new disk, will I retrieve my VMs that are actually stored on other disks?
-
- kern.log, dmesg, the usual suspects.
- if you have a metadata backup yes. Otherwise, you'll need to re introduce the SR, and just have to recreate your VMs and attach the existing disks to it (and without the metadata info, if your disks are all the same size, it could take same some time to find who's who)
-
@olivierlambert I could access the SSD, filesystem was corrupted. I don't think I have a backup at hand just in case I would not be able to boot at all. What files could I transfer to get all my VMs back to normal after a clean install on a new disk?
-
@olivierlambert System restarted, not sure how to backup XCP-NG server side properly though. I ran a backup of XO metadata and pool parameters.
-
XCP-ng pool metadata backup is exactly what you needed in that case
