XCP-ng 8.3 updates announcements and testing

robertblissitt

@abudef After the excitement from the last update cycle (see my post above from ~January 29), I kicked off a Rolling Pool Reboot this time before considering a Rolling Pool Update. During this RPR, the first host is currently hanging on its shut down right now after about 10 - 15 minutes as shown in the screenshot. I am running the previous most recent version of XCP-ng, again from January 29, 2026. I'll revisit installing these most recent updates once I get clean reboots.

@robertblissitt Press ESC and you'll see what's happening

Normal for the pool master to take a bit longer but never seen 15 minutes before.

As explained, I haven't observed such a delay on our end during our testing.

As Maniix suggests, you can see what's happening by pressing "Esc" to see which step is taking longer.

From what I've heard internally, a common reason for this lengthy step is when a shared server was running on a VM and that VM was shut down. The host then takes a very long time to shut down or restart.

In my homelab I've had the same problem for at least 18 month's
when shutting down the XO-VM it hangs for 2-3 minutes when it tries to umount the remotes

umount /run/xo-server/mounts/xxxxx (SMB and NFS)
umount /run/xo-server/mounts/yyyyy (SMB)

I did report this in an earlier thread

manilx

@ph7 This I can confirm, with XO VM.
But discussion was about the host....

gduperrey

For XO, I suggest you start a separate thread.

Regarding the host issue, without more details or information, it's difficult to say anything at the moment, especially since I haven't been able to reproduce it myself.

@gduperrey Absolutely understand. I didn't now about the Escape key as Manilx mentioned. Next time, I will press Esc to see if there is any useful information and report it here. This was just new behavior and wanted to report it informally.

In my case, I gave the command to shut down all hosts, and the master "made it" first. The other hosts then got "stuck" at this point for a very long time:

EDIT: Apparently waiting for umount:

gduperrey

@abudef In case of a shutdown, I turn off the secondary servers first. Once they are off, I shut down the primary server. This ensures that if the secondary servers have information to send to the primary, they can do so, whereas otherwise, they can wait to shut down.

In case of a pool reboot, I reboot the primary server first, and once it is accessible, I reboot the secondary servers.

@gduperrey Of course, the order matters. Now everything seems to be clear.
