Hi, Basically Ubuntu delivers back-ported kernels as part of the official point releases, so DRBD gets upgraded too. Usually all 8.4.x versions are compatible with 8.4.y tools, so I'm suprised you have connection errors. We did have a problem during the ubuntu 12.04 timeframe because Ubuntu skipped from DRBD 8.3 to 8.4 - - eventually they patched the tools to make them compatible with both. It took them and quite a bit of testing to fix that, so by all means please file a bug report against Ubuntu. Anyway, one option you have is to downgrade to one of the previous kernels (search for packages named "linux-.*-lts-.*"). Another option is to compile the tools on your own, it's quite easy on Ubuntu.
