> In fact this seems to have killed cluster communication, because I saw that "DLM start" timed out. The other nodes were unable to use DLM during that time (while the node could not join).

During boot the problem node was able to join the cluster as before. In the meantime I had also updated the third node without a problem, so it looks like a rare race condition to me.
