I reply your message but the infos here should answer even the infos asked from Alwin... I send directly the output differences from the command pveversion with -v flag because all three nodes show the same "pve-manager/6.3-6/2184247e (running kernel: 5.4.106-1-pve)" version. So I have launched the following command in all three nodes: # pveversion -v > pveversion.$(hostname) obtaining 3 differents files and I've done the diff between the first two files (referring to pve01 and pve02) and as expected there is no difference: $ diff pveversion.pve0{1,2} Then I have done the diff between the first and the third node and this is the result: $ diff pveversion.pve0{1,3} 5d4 < pve-kernel-5.3: 6.1-6 8,9c7 < pve-kernel-5.3.18-3-pve: 5.3.18-3 < pve-kernel-5.3.10-1-pve: 5.3.10-1 --- > pve-kernel-5.4.34-1-pve: 5.4.34-2 there are some little differences yes but in kernel that are not in use any more (in all 3 nodes uname -r shows 5.4.106-1-pve)... Attached you can find all three files hoping the system doesn't cut them. Please can I ask you if you have a 6.3 node in your installations that was previously in 6.2 version (i.e. not installed directly in 6.3 version)? Can you tell me if the "Boot order" musk is the one with only combo boxes or the more evoluted drag and drop musk? Thank you very much Piviul
