Hi! Are there any errors shown for Ceph or when listing images manually for that rbd storage?

Hi! It's best to show your interest in a specific Bugzilla entry so that we can track the interest in certain features. There's for example [0] for the general interest of adding any SMBIOS type information and/or [1] for automatically generating these serials. There's already support to...

Hi! Is there any syslog entry on the host or in the Debian VM when rebooting from inside the VM?

Hi! With GET /cluster/ha/rules and GET /cluster/ha/rules/{ruleid} you receive a digest value (of the whole config). If you provide this digest as an argument to PUT /cluster/ha/rules/{ruleid}, then the API handler will refuse to make changes to the HA rules if the digest (i.e. the rules...

The former one is just an alias for the latter one [0] ;) [0] https://manpages.debian.org/trixie/apt/apt.8.en.html

This fix is already done upstream [0] and for our patched ifupdown2 packages as well before Proxmox VE 9 was released, so this can only happen if the ifupdown2 package is somehow held back (e.g. using apt upgrade instead of apt dist-upgrade, which have different semantics how to upgrade). Make...

Hi! Um welches Netzwerkinterface handelt es sich? Wenn der Intel e1000e-Treiber verwendet wird, hilft womöglich die Information in [0]? Wenn die Fehlermeldungen direkt auf den Terminal tty0 gehen, könntest du einen anderen Terminal verwenden. Normalerweise wird stdout nicht als stdin...

Das wird durch den Fencing-Mechanismus sichergestellt: Standardmäßig verwendet der HA Stack das softdog Kernel Modul, welches unter Normalbedingungen in regelmäßigen Abständen diesen Watchdog resettet. Das kann aber nur passieren, wenn das LRM der Node auch das Node-eigene LRM-Lock besitzt...

Hi! Wenn "im Netzwerk isoliere" bedeutet, dass die Node keine Verbindung mehr zu den anderen Nodes in dem Cluster hat, dann würde das bedeuten, dass dadurch die ganze Node gefenced wird auf der die HA-Container laufen. Das bedeutet dann wiederum, dass auch Nicht-HA Gäste durch das Fencing...

Hi! Proxmox distributes its own patched ifupdown2 packages, so it's best to check if these issues are because of changes done there first. Either way, it should be checked out properly by creating a Bugzilla entry for this. Also the ifupdown2 version is from May 2023, while the most current...

From the apt history it looks like there was an in-between upgrade to many packages from Proxmox VE 9: Start-Date: 2025-10-05 16:21:44 Commandline: apt upgrade Install: [...] proxmox-kernel-6.14:amd64 (6.14.11-3, automatic), libjs-bootstrap5:amd64 (5.2.3+dfsg-8, automatic)...

Hi! I haven't tried to reproduce it yet: When was the update performed? Has the watchdog been inactive before already (some recent entries in journalctl -u watchdog-mux)?

Yes, apt dist-upgrade/apt full-upgrade must be used instead of apt upgrade as described in [0], because among other things the latter will make packages stay on a lower versioned package instead of resolving the package dependencies correctly. On which versions were you on Proxmox VE 7, 8, and...

Hi! What network does corosync run on? Does it have a dedicated network interface or is it shared with some other network resources? These are quite high numbers, the network should have a very low latency. [0] This seems like that for some reason the HA was interrupted while reading/writing...

Hi! Could you post some syslog on these nodes? Is HA setup on these nodes?

Does the performance improve if you upgrade to a newer version of pve-manager? There were some performance-related improvements in pve-manager >= 9.0.8.

Hi! Which exact version of pve-manager have you upgraded to (e.g. pveversion)? Could you post a syslog from one of the nodes you are experiencing the problems on?

Hi! What is the config of such a VM that fails to migrate (output of qm config <vmid>)? What does the tasklog show if the VM is migrated through HA? What does it show if the VM is migrated manually (does it work that way?)?

Hi! Which web guide are you referring to? HA groups have been deprecated in favor of the (semantically) equivalent HA node rules in Proxmox VE 9. The reason was primarily to aggregate those relationships in a single view, allow further extensions and make the interactions between node affinity...

Hi! Have you upgraded the Proxmox VE host from version 8 to 9 or is it a new install? Either way, HA groups have been deprecated in favor of HA node affinity rules and these are feature-compatible, even though they are presented slightly different. This includes that the "nofailback" flag is...
