Dear DRBD users, This is version 0.5.3 of DRBD Reactor. It fixes a bug where under certain conditions information about peer disks and paths got lost on connection updates. As this affected the core in theory all plugins that use that information are affected as well. The bug was found by a customer in the UMH plugin for example that did not trigger on peer device changes. All users should update. While fixing this bug I also saw that some environment variables set by the UMH plugin did not match their documented names. This got fixed.
Some more details: Reactor uses the (drbdsetup) events2 stream and updates objects on DRBD event updates. Usually the information in events2 is 1:1 what Reactor saves in its internal structs. If we get an update (a "change event" in events2 speak), we just overwrite the existing struct with the new content. What was overlooked is that the connection struct not only holds its own information, but also the structs for peer devices and paths. So on connection changes peer devices and paths got overwritten with their default slices of structs which are empty. This is now fixed, existing peer devices and paths are copied to the update.
