But there are some situations, where the local pmxcfs (pve-cluster) restarts and loses that information. Basically everytime we restart the pmxcfs without restarting pvestatd too. For example, on a cluster join, or if the pmxcfs has been restarted manually. By additionally checking if the local kv-store of the pmxcfs has any version info for the node, we can decide if another broadcast is necessary. Therefore after the next run of pvestatd, we should have the full version info available again. Signed-off-by: Aaron Lauterer <a.laute...@proxmox.com> --- This patch is preparation to get reliable version infos as I am picking of the patch series of Folke to include more metrics into the RRD data and summary graphs. [0] This was a big blocker and now with the major version change coming up, we at least can assume the latest 8.x installed as part of the update to PVE 9. Therefore, we should get this in with PVE 8. Additional patches for PVE 8 will follow to make the transition smoother. But as mentioned, this here is one of the things that needs to work reliably, which is why I submit the patch already now.If we start relying more on this, we likely also want: https://lore.proxmox.com/pve-devel/20221006125414.58279-1-f.eb...@proxmox.com/
Hmm, honestly, I might prefer having the last known version info still present. That would make it easier to determine if all cluster nodes are on at least a required version ;).
But I think it would be better, with RRD data migration in mind, to make it mandatory that all cluster nodes are online before one can proceed instead of relying on stale version infos.
