I have 2 server which will node for cluster (vrtx M640) . I performed cluster validation and all the time I received warnings that servers not running the same updates. It is strange because according to update history they have installed same software. Another thing is that one KB - 4462930 is missing on one of the server ( on other server was installed ). I tried download it and install manually but I reveiced message that this is not applicable on this computer. I checked and it seeams that on one server first was installed KB4462930 and than newest Adobe updates -KB4561600 and on this node all is ok, on second node first was installed KB4561600 (success) and then attempt to install KB4462930 (failure). I suspect that in this case newest KB contains 4561600 thats why I failed to install it (but I am not sure).
Anyway please help with this strange behavior during cluster validation, I need make cluster without any warning:)
Below I attached screnshot from server1, server2, cluster validation report:
