Well, it may happen seamless unless you reboot the machine before it has completed the resyncing with the other (still 8.3 running) machine. I happened to require yet some other kernel setting (unrelated to DRBD), installed the changed kernel, while one DRBD resource was still syncing (for the first time after upgrading to 8.4), and rebooted (clean shutdown/restart). After the reboot, DRBD complained about not finding valid meta data on the device, and I had to write new metadata and perform a full sync to rectify the situation. (Luckily, since the other machine was still running, so no data was lost in the process.) Regards, Lutz Vieweg
